5. Operation Principle

Upon power on, the Sigfox node has 60 seconds to wait for off-line configuration (via cable with ModbusRTU protocol)

After 1 minute 30 seconds later the device will send the first data packet and at the same time wait for the downlink packet from the Base Station.

Then during the operation, there are 03 cases of sending data to base station:

1. When the sensor sampling time interval is reached, the Sigfox node will read the data from Input or sensor and performing the calculation. After that it will check calculated value with alarm thresholds. If the calculated was out off the threshold values (Lo or Hi), called alarm, and the number of times of alarm did not pass the limit of number of alarms, then it will send data to Base station immediately;

NOTE: 

Once sending the data to base station by this alarm event, the timer of sending time interval will be reset;

2. When the sending time interval is reached, it will send data to Base station immediately, regardless of value;

3. By using the magnet key, the Sigfox node can be triggered to send data to base station immediately. There will be a beep sound from the buzzer meaning the data has been sent. (Buzzer will be updated in the latest version)

5.2 Button Function

5.2.1 Menu configuration

There are 3 configuration menus: tx_repeat, downlink_flag, radio configuration.

We use the button to enter the menus as follows:

5.2.1.1 tx_repeat

Press and hold the button 2s  ->  When the Red LED is on, it means entering the tx_repeat configuration menu. Then release to configure it.

Press to configure. After pressing if the Red LED flashes once, tx_repeat = 0 (send 1 time). After pressing if the Red LED blinks twice, it is tx_repeat = 1 (send 3 times).

Press and hold the button 5s  ->  When the Green LED is on, it means entering the downlink_flag configuration menu. Then release to configure it.

Press to configure. After pressing if the Green LED flashes once, it is downlink_flag = 0 (downlink is not allowed). After pressing if the Red LED blinks twice, it is downlink_flag = 1 (downlink is allowed).

5.2.1.3 radio configuration

Press and hold the button 10s  ->  Blue LED is on, it means entering the Radio Configuration menu. Then release to configure it.

Press to configure. After pressing if the Blue LED blinks once, it is Radio Configuration = 1. After pressing if the Blue LED flashes twice, it is Radio Configuration = 2. After pressing if the Blue LED flashes 4 times, it is Radio Configuration = 4.

5.2.2 Exit the menu:

There are 3 ways to exit the menu:

  • Press and hold for 3s, the LED turns off to exit the menu;
  • Wait 30 seconds, then exit the menu;
  • Take out the battery, it all starts over (outside the menu)).

5.3 RC technical details

The RF transmit power will be automatically set as the max value as allowed by the Zone.

Sigfox Radio Configuration (RC) defines the radio parameters in which the device shall operate: Sigfox operating frequencies, output power, spectrum access mechanism, throughput, coexistence with other radio technologies, etc.

Each radio configuration includes 4 uplink classes: 0u, 1u, 2u, and 3u.

The Sigfox network globally works within the ranges from 862 to 928 MHz. But not all RCs require such a wide range of operation.

  RC1 RC2 RC4
Uplink center frequency (MHz) 868.130 902.200 920.800
Downlink center frequency (MHz) 869.525 905.200 922.300
Uplink data rate (bit/s) 100 600 600
Downlink data rate (bit/s) 600 600 600
Sigfox recommended EIRP (dBm) 16 24 24
Specifics Duty cycle 1% * Frequency hopping ** Frequency hopping **
* Duty cycle is 1% of the time per hour (36 seconds). For an 8 to 12 bytes payload, this means 6 messages per hour, 140 per day.

** Frequency hopping: The device broadcasts each message 3 times on 3 different frequencies. Maximum On time 400 ms per channel. No new emission before 20 s.

*** Listen Before Talk: Devices must verify that the Sigfox-operated 200 kHz channel is free of any signal stronger than −80 dBm before transmitting. 

Sigfox’s high limit EIRP recommendation is included in each column although regulations sometimes allow for more radiated power than the Sigfox recommendation.

Sigfox’s recommendation is set to comply with the Sigfox technological approach of:

  • Low current consumption
  • Balanced link budget between uplink and downlink communication

5.5 Process of measurement

When the sensor sampling time interval is reached, for example 2 minutes, the Sigfox node will wake up and switch ON the power supply to supply the energy to external sensor to start the measurement. Depends on the type and characteristic of external sensor, the sensor will take a certain time to finish the measurement.

Once reading the value, it can be scaled to any engineering value by the following formula:

Y = aX + b

Where:

      • X: the raw value from sensor
      • Y: the calculated value will be sent to Sigfox base station in the payload data.
      • a: constant (default value is 1)
      • b: constant (default value is 0)

So, if there is no user setting for a and b ==> Y = X

The Y value will be compared with Lo and Hi threshold. Please refer below the graph of alarm processing.

7. Installation

7.1 Locate the good place for Radio signal

To maximize the distance of transmission, the ideal condition is Line-of-sight (LOS) between the Sigfox sensor and Base station. In real life, there may be no LOS condition. However, the Sigfox sensor still communicate with Base station, but the distance will be reduced significantly.

ATTENTION:

DO NOT
install the Sigfox sensor or its antenna inside a completed metallic box or housing, because RF signal can not pass through metallic wall. The housing is made from Non-metallic materials like plastic, glass, wood, leather, concrete, cement…is acceptable.

WSSFC-PPS-H3.png

7.2 Process mounting

WARNINGS:

1. Please make sure the fluid is suitable with the wetted materials of the sensor. Please refer sensor specification;
2. Please make sure the operating temperature and pressure is suitable with the sensor. Please refer sensor specification;
3. Prepare the professional tools for installation. The inappropriate tools may cause damage to the sensor.

DANGER:

1. The installer need to be equipped with full Safety gears during installation, such as safety glasses, safety shoes, safety cloths, safety mask...Please follow the safety instructions of the installation site;
2. The installer must be qualified for this installation job;
3. The installer must be permitted by Site's owner for performing the installation;

  • Consider to use the isolation valve 1/2" or 1/4" to isolate the media and the sensor during maintenance;
  • Fully closing the isolation valve during installation and maintenance the sensor;
  • Fully open the isolation valve during normal operation;

There are two ways of process mounting as below.

7.2.1 Mounting direct on Pipe

  • The total weight of the sensor MUST be within the permitted load of the pipe to be installed;
  • Consider to build the support for the pipe if the sensor weight is larger than the permit;
  • Below picture shown without the isolation valve, but we highly recommend to use isolation valve.

WSSFC-PPS-H2.png

7.2.2 Remote mounting on wall or pole

  • Make sure the wall or place of pole for mounting is not covered or affected by the surrounding metallic objects;
  • Using the metal tubing and fittings for interconnection between process pipe and sensor process connector;
  • The metal tubing and fitting materials, and size must be sizing properly to suit the process conditions;
  • It is better to install the isolation valve next to sensor process connector.

7.3 Battery installation
