1. Quick Guide
Reading time: 10 minutes
Finish this part so you can understand and put the sensor in operation with the default configuration from the factory.
1.1 What is the Sigfox-Ready AC Current Sensor and its principle of operation?
WSSFC-AC is a Sigfox-Ready sensor with an integrated AC current measuring transducer that can measure the AC current from a current transformer with max 5A AC current. It is compatible with any brand of current transformer (CT) on the market which gives an output max of 5A AC. The CT ratio will be selected based on the load current.
It is battery-operated and able to connect to any Sigfox network in the World. It supports all frequency zones such as RC1, RC2, RC3c, RC4, RC5, RC6, and RC7.
For the principle operation of the AC current sensor, please refer to this link.
1.1.1 What are the typical applications of this sensor?
Please refer to this link for typical applications.
1.1.2 When does the device send uplink messages?
The device will send uplink messages in the following cases:
- Case 1: After power-up in the 60s, the device will send the first message called START_UP. The payload will tell the user the HW version, FW version, and current configuration of the device;
- Case 2: Then, in every interval time (pre-configured), for example, 10 minutes, it will send the message called CYCLIC_DATA. The payload will tell the user the following data like measured value (AC current value), battery level, alarm status...
To change the cycle of data sending, you can change the value of the parameter: CYCLIC_DATA_PERIOD (default is 600 seconds).
- Case 3: In case the Alarm function was enabled (in the configuration of the sensor), if the measured value passed the threshold, it will send the uplink message immediately. This message is called ALARM. The payload also tells the user the data like measured value (AC current value), battery level, alarm status...
The alarm thresholds can be changed via downlink or offline tools.
- Case 4: The HEART_BEAT uplink message will be sent once a day (the default setting, can be changed in configuration) to allow the Sigfox back-end system can send the downlink message for changing the configuration of the sensor. Please refer to the downlink section for more details. The uplink payload will tell the user the HW version, FW version, and current configuration of the device;
- Case 5: During commissioning, testing, or calibration sensor, the user can force the device to send the uplink message so that they can get the data immediately. This message is called FORCE_DATA. The payload will provide data like raw measured value, scaled measured value, battery level, alarm status... It can be forced by applying the magnet key on the reed switch in 1s;
- Case 6: In case users want to change the configuration immediately, they don't need to wait up to 1 day for the HEART_BEAT message, instead they can force the device to send a special uplink message so that the device can get the new downlink message. This uplink message is named PARAMETERS_UPDATE. It can be forced by applying the magnet key in more than 5s.

3. Advanced Guide
3.1 Operating principle of the Sigfox-Ready AC current sensor
3.1.1 Operating principle of the complete device
The Daviteq Sigfox-Ready AC current sensor comprises 02 parts connected together as shown below picture.
- The Daviteq Sigfox-Ready wireless transmitter;
- The Daviteq AC 5A current Transducer;
The AC current transducer is to measure the actual AC current of the secondary winding of the CT.
The Sigfox-Ready is to read the AC current value from the transducer and perform the scaling (A and B values, during calibration). The scaled current will be multiplied by the CT ratio to deliver the final value which is the actual load current that the user wants to measure.
Scaled_CT_Current = A x CT_Current + B
Actual_Load_Current = Scaled_CT_Current x CT
Where:
A : Constant A
B : Constant B
CT_current: the measured current from the transducer (Secondary winding current of the CT)
For example: the CT_current = 1.5A, the CT ratio = 20 (the CT is 100/5), A=1, B=0 ==> then the Actual_Load_Current = 1.5 x 20 = 30A
Note: the Low cut value of Actual_Load_Current is 0.5A. That meant the device can not measure the current load less than 0.5A
3.1.2 Operating principle of AC current transducer
To understand how the AC current transducer can measure AC current, please refer to this link for a complete understanding of this measuring technique.
3.1.3 Some important configuration parameters
Below are some important configuration parameters which affect the operation of the device like battery life, measurement accuracy, and alert threshold.
For Battery life estimation, please refer to this link.
- measure_period | Default = 600s
This is the time period for the wireless transmitter to wake up and take the measurement from the transducer. The default value is 600s. Users can reduce this value, but smaller value, shorter battery life! - cyclic_data_period | Default = 600s
Interval time to send an uplink message regardless of any conditions - sensor_boot_time | Default = 1000mS
This value will affect the measurement accuracy. DO NOT change this value!
Those configuration parameters can be changed by downlink or offline tools. For more other configuration parameters, please refer to the next section.
3.2 Sensor Configuration

1. Quick Guide
Reading time: 10 minutes
Finish this part so you can understand and put the sensor in operation with the default configuration from the factory.
1.1 What is the Sigfox-Ready V1A Single-Axis Vibration Sensor and its principle of operation?
WSSFC-V1A is a cost-effective, single-axis vibration sensor designed for condition monitoring and preventive maintenance applications. The piezo-electric accelerometer is available in ranges ±25g or 50g and features a flat frequency response up to >10kHz. Its accelerometer feature a stable piezo-ceramic crystal in shear mode with low-power electronics, sealed in a fully hermetic package. The Piezo Electric technology incorporated in the WSSCF-V1A accelerometer has a proven track record for offering the reliable and long-term stable output required for condition monitoring applications. The accelerometer is designed and qualified for machine health monitoring and has superior Resolution, Dynamic Range, and Bandwidth to MEMS devices. Besides that, it can also measure the temperature at the mounting point.
It is battery-operated and able to connect to any Sigfox network in the World. It supports all frequency zones such as RC1, RC2, RC3c, RC4, RC5, RC6, and RC7.
For the principle operation of the V1A single-axis vibration sensor, please refer to this link.
1.1.1 What are the typical applications of this sensor?
Please refer to this link for typical applications.
1.1.2 When does the device send uplink messages?
The device will send uplink messages in the following cases:
- Case 1: After power-up in the 60s, the device will send the first message called START_UP. The payload will tell the user the HW version, FW version, and current configuration of the device;
- Case 2: Then, in every interval time (pre-configured), for example, 10 minutes, it will send the message called CYCLIC_DATA. The payload will tell the user the following data like measured values, battery level, alarm status...
To change the cycle of data sending, you can change the value of the parameter: CYCLIC_DATA_PERIOD (default is 600 seconds).
- Case 3: If the Alarm function was enabled (in the configuration of the sensor), if the measured value passed the threshold, it will send the uplink message immediately. This message is called ALARM. The payload also tells the user the data like measured values, battery level, alarm status...
The alarm thresholds can be changed via downlink or offline tools.
- Case 4: The HEART_BEAT uplink message will be sent once a day (the default setting can be changed in configuration) to allow the Sigfox back-end system can send the downlink message for changing the configuration of the sensor. Please refer to the downlink section for more details. The uplink payload will tell the user the HW version, FW version, and current configuration of the device;
- Case 5: During commissioning, testing, or calibration sensor, the user can force the device to send the uplink message to get the data immediately. This message is called FORCE_DATA. The payload will provide data like raw measured value, scaled measured value, battery level, alarm status... It can be forced by applying the magnet key on the reed switch in 1s;
- Case 6: If users want to change the configuration immediately, they don't need to wait up to 1 day for the HEART_BEAT message, instead they can force the device to send a special uplink message so that the device can get the new downlink message. This uplink message is named PARAMETERS_UPDATE. It can be forced by applying the magnet key in more than 5s.

3. Advanced Guide
3.1 Operating principle of the Sigfox-Ready AC current sensor
3.1.1 Operating principle of the complete device
The Daviteq Sigfox-Ready AC current sensor comprises 02 parts connected together as shown below picture.
- The Daviteq Sigfox-Ready wireless transmitter;
- The Daviteq AC 5A current Transducer;
The AC current transducer is to measure the actual AC current of the secondary winding of the CT.
The Sigfox-Ready is to read the AC current value from the transducer and perform the scaling (A and B values, during calibration). The scaled current will be multiplied by the CT ratio to deliver the final value which is the actual load current that the user wants to measure.
Scaled_CT_Current = A x CT_Current + B
Actual_Load_Current = Scaled_CT_Current x CT
Where:
A : Constant A
B : Constant B
CT_current: the measured current from the transducer (Secondary winding current of the CT)
For example: the CT_current = 1.5A, the CT ratio = 20 (the CT is 100/5), A=1, B=0 ==> then the Actual_Load_Current = 1.5 x 20 = 30A
Note: the Low cut value of Actual_Load_Current is 0.5A. That meant the device can not measure the current load less than 0.5A
3.1.2 Operating principle of AC current transducer
To understand how the AC current transducer can measure AC current, please refer to this link for a complete understanding of this measuring technique.
3.1.3 Some important configuration parameters
Below are some important configuration parameters which affect the operation of the device like battery life, measurement accuracy, and alert threshold.

1. Quick Guide
Reading time: 10 minutes
Finish this part so you can understand and put the sensor in operation with the default configuration from the factory.
1.1 What is the Sigfox-Ready V1A Single-Axis Vibration Sensor and its principle of operation?
WSSFC-V1A is a cost-effective, single-axis vibration sensor designed for condition monitoring and preventive maintenance applications. The piezo-electric accelerometer is available in ranges ±25g or 50g and features a flat frequency response up to >10kHz. Its accelerometer feature a stable piezo-ceramic crystal in shear mode with low-power electronics, sealed in a fully hermetic package. The Piezo Electric technology incorporated in the WSSCF-V1A accelerometer has a proven track record for offering the reliable and long-term stable output required for condition monitoring applications. The accelerometer is designed and qualified for machine health monitoring and has superior Resolution, Dynamic Range, and Bandwidth to MEMS devices. Besides that, it can also measure the temperature at the mounting point.
It is battery-operated and able to connect to any Sigfox network in the World. It supports all frequency zones such as RC1, RC2, RC3c, RC4, RC5, RC6, and RC7.
For the principle operation of the V1A single-axis vibration sensor, please refer to this link.
1.1.1 What are the typical applications of this sensor?
Please refer to this link for typical applications.
1.1.2 When does the device send uplink messages?
The device will send uplink messages in the following cases:
- Case 1: After power-up in the 60s, the device will send the first message called START_UP. The payload will tell the user the HW version, FW version, and current configuration of the device;
- Case 2: Then, in every interval time (pre-configured), for example, 10 minutes, it will send the message called CYCLIC_DATA. The payload will tell the user the following data like measured values, battery level, alarm status...
To change the cycle of data sending, you can change the value of the parameter: CYCLIC_DATA_PERIOD (default is 600 seconds).
- Case 3: If the Alarm function was enabled (in the configuration of the sensor), if the measured value passed the threshold, it will send the uplink message immediately. This message is called ALARM. The payload also tells the user the data like measured values, battery level, alarm status...
The alarm thresholds can be changed via downlink or offline tools.
- Case 4: The HEART_BEAT uplink message will be sent once a day (the default setting can be changed in configuration) to allow the Sigfox back-end system can send the downlink message for changing the configuration of the sensor. Please refer to the downlink section for more details. The uplink payload will tell the user the HW version, FW version, and current configuration of the device;
- Case 5: During commissioning, testing, or calibration sensor, the user can force the device to send the uplink message to get the data immediately. This message is called FORCE_DATA. The payload will provide data like raw measured value, scaled measured value, battery level, alarm status... It can be forced by applying the magnet key on the reed switch in 1s;
- Case 6: If users want to change the configuration immediately, they don't need to wait up to 1 day for the HEART_BEAT message, instead they can force the device to send a special uplink message so that the device can get the new downlink message. This uplink message is named PARAMETERS_UPDATE. It can be forced by applying the magnet key in more than 5s.
1.1.3 The important configuration parameters
The sensor was pre-configured at the factory with default values for configuration parameters that meet most use cases. However, depending on the specific use case, the customer can adjust those parameters. Please refer to section 3.2 for more details.
1.1.4 What kind of battery is used for this sensor?
The sensor is powered by 2 x AA 1.5V batteries for many years of operation. We do recommend using Energizer L91 battery which is very popular and high performance. This battery has a capacity of up to 3500mAh with a working temperature range from -40 to +60 oC. The instruction for installing the batteries is in this link.

Step 1: Prepare the values of communication settings:
|
Device ID |
Get Devive ID on the device nameplate |
|
Device PAC |
Get Devive PAC on the device nameplate |
Note: All Sigfox sensors are pre-configured with the correct RC before delivery. The settings of Device ID, Device PAC, and RC could also be read from the device memory map. Please reference section 3.2 Sensor configuration for details.
Step 2: Add the device to Sigfox Backend
Please refer to this link for details
Step 3: Install the batteries to the device
Please refer to this link for instructions on battery installation.
After installing the battery in 60 seconds, the first data packet will be sent to the Sigfox network. After receiving the first data packet, the time of another packet depends on the value of the parameter: CYCLIC_DATA_PERIOD. Additionally, you can use a Magnet Key to force the device to send data instantly.
Step 4: Decode the payload of receiving package
Please refer to section 1.4 Uplink Payload and Data Decoding for details of decoding the receiving packet to get the measured values.
