4.2 The principle of operation of the LoRaWAN sensor

When starting the power supply, the LoRaWAN sensor has 60 seconds to allow configuration to operate via the Configuration Cable with the Modbus RTU protocol. After 60 seconds, the first packet will be sent, then the LoRaWAN sensor will send the next packets in the following cases:

    • Case 1:
      • When it reaches the frequency of taking data, the LoRaWAN sensor will wake up to measure and calculate. Then:
        • If the measured value exceeds the High or Low setting thresholds, the packet will be sent to the Gateway and then asleep;
        • If NOT then sleep without sending data.

          NOTE:

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

    • Case 2: When the sending time interval is reached, the LoRaWAN sensor wakes up to measure and calculate and send data to Gateway immediately, regardless of value.
    • Case 3: By using the magnet key, the LoRaWAN sensor can be triggered to send data to Gateway immediately.

    NOTE:

    The time between sending data for Class A is at least 3 seconds

    WSSFCEX-PPS-H9.png

    WSLRW-AG-H12.png WSLRW-AG-H13.png

    4.3 Principle of operation LoRaWAN Network

    WSLRW-PPS-H6.png

    The LoRaWAN Gateway function is Packet Forwarder so:

    • Between Gateway and End Device: Gateway receives data packets from End Device via RF connection, so it is recommended to configure Radio parameters (Note: the packet that Gateway receives is encrypted)
    • Between Gateway and Network Server: Gateway forwards data packets to the Network server via an IP connection, so it is recommended to configure Network parameters such as Server Address, Server Uplink Port, Server Downlink Port, ..

    LoRaWAN Network is secured as follows:

    • Network section key (NwkSKey) to ensure the security of communications on the Network
    • Application session key (AppSKey) to ensure data security between End Device and Application Server
    • Special keys of the device such as DevEUI, AppEUI, Gateway EUI, Device Address. Therefore, the data packet that the Gateway receives is encrypted and decrypted on the Application server.

    To End Device connect to the Network server, you need to register in the following two ways:

    • Activation with OTAA (Over-the-Air activation): is the process of joining the Network automatically. Previously, both End Device and Application Server installed the same DevEUI code, AppEUI and AppKey. During activation, AppKey will generate 2 security keys for End Device and Network, which are:
      • Network session key (NwkSKey): is the key to secure communication commands on MAC layer between End Device and Network server.
      • Application session key (AppSKey): is the key to secure data packets between End Device and Application server.

    ATTENTIONS:

    * OTAA mode must be successfully activated in order for the End Device to send data packets to the Network through the Gateway;

    * OTAA mode only need to activate once, if the device is reset or battery replacement, it will activate OTAA again;

    * When the End Device is connected to the Network server, whether the Gateway is reset or the power is restarted, it will not need to activate OTAA.

      • Activation by ABP (Activation by Personalization): is the process of joining Network manually. Device Address, Network session key (NwkSKey) and Application session key (AppSKey) codes must be stored inside the End Device and Application server, so when the End Device sends data packets to the Network server, it will also send the security codes to activated.

      4.4 Configure the LoRaWAN Network

      4.4.1 Configure End Device operation according to OTAA

      Configuration parameters for the End Device to be activated by OTAA as the table below:

      Key Number for generating 2 NwkSKey and AppSKey security keys created by the user (factory-created by default)
      => Used to install for both the Device and Application Server End

      ATTENTIONS:

      * The AppEUI number from Application Server => then installed for the End Device. AppEUI is randomly generated by the Application server or by the user;

      * The number of AppKeys during OTAA activation will generate two security keys, Lora NwkSKey and AppSKey, which are used for both End Device and Network.

      4.5 LED meaning

      • RED LED: 

        • Fixed ON: due to noise caused peripheral components (i2c, spi, uart, timer, rtc, wdt, ...) do not initialize.
        • Flashing 10ms ON / 10s OFF: Activation by OTAA on the Network server failed.
        • Flashing 10ms ON / 2s OFF:  Sending data packet to Gateway failed.
      • GREEN LED: Flashing 100ms ON / OFF when sending data packet to Gateway.
      • BLUE LED:
        • Flashing 1s ON / 1s OFF for the first 60 seconds when booting (insert batteries or connected external sources), after 60 seconds OFF.
        • ON during the LoRaWAN sensor receives data packets from the Network server and OFF when received.

      4.6 Process of measurement

      When the LoRa sensor wakes up, it will supply power to the external sensor module so that the module can start measuring. After measuring it will turn off the power to the module.

      The measured value is the raw value of the sensor module, which can be ambient temperature, ambient humidity, etc.

      The measurement value can be scaled according to the following formula:

      Y = aX + b

              • X: the raw value from module 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)

      4.7 Payload Data

      The folllowing is the format of payload data will be sent to Sigfox server. Length is 6 bytes, it is future-proof for expansion to 12 bytes.

      5. Configuration

      Using the configuration cable to connect to the sensor as below picture.

      WSSFC-ULC-H15.png

      Serial port configuration on the computer:

      * COMPort, Baudrate: 9600, Parity: None, Stop bit: 1, Data bit: 8

      * Modbus RTU: Reading data by Function 3 / Writing data by Function 16.

      5.1 Step to configure

      NOTE:

      The Modbus configuration can only be performed in the first 60s after power up the LoRaWAN sensor. After 60s, if user can not finish the configuration process, user need to reset the power of LoRaWAN sensor again, by removing battery in at least 15s.

      Step 1: Install the Modbus Configurator Software in the link below

      https://filerun.daviteq.com/wl/?id=qK0PGNbY1g1fuxTqbFW9SXtEvCw7bpc6

      6. Installation

      6.1 Installation location

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

      ATTENTION:

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

        WSLRW-PT100-H5.png

        6.2 Sensor connection

        Connect the sensor to the Pt100 thermal probe

        WSLRW-PT100-H2.png WSLRW-PT100-H4.png

        Step 1: Using L hex key to unscrew M4 screws at the side of housing and carefully pull out the top plastic housing in the vertical direction

        Step 2: Put the signal wires through the PG9 port to connect the sensor

        Step 3: Connect the wires that correspond to the label on the sensor

        WSLRW-PT100-H11.png

        Step 4: Insert the top plastic housing and locking by L hex key

         

        6.3 Battery installation

        WSLRW-ATH-H7.png

        Steps for battery installation:

        Step 1: Using L hex key to unscrew M4 screws at the side of housing and carefully pull out the top plastic housing in the vertical direction

        WSLRW-PT100-H9.png

        Step 2: Insert 02 x AA 1.5VDC battery, please take note the poles of battery

        ATTENTION:

        REVERSED POLARITY OF BATTERIES IN 10 SECONDS CAN DAMAGE THE SENSOR CIRCUIT!!!

        WSLRW-PT100-H12.png

        Step 3: Insert the top plastic housing and locking by L hex key

        ATTENTION:

        When reinstalling the cover, pay attention to put the PCB edge into the middle slot of the box inside as shown below)

        WSLRW-PPS-H26.png

        7. Troubleshooting

        No. Phenomena Reason Solutions
        1 The BLUE LED does not blink when the battery is installed

        Insert the battery in the opposite direction

        Insert the battery in the correct way

        2 The RED LED is always on Due to noise, the peripheral components (i2c, spi, uart, ..) of RF module cannot be initialized After 30s the node will automatically reset. If the noise causes the Watchdog not to initialize, remove the battery and wait for more than 10 seconds, then insert the battery again
        3 The RED LED blinks continuously (10ms ON / 2s OFF) and the Node does not send RF. After more than 10 sending cycles, the Node will automatically reset
        • Operating frequency in that country is prohibited
        • Operating frequency in that country is limited to Data rate, Tx Power
        • Reconfigure the allowed frequency of operation
        • Reconfigure Data rate = DR5 / SF07, Tx Power
        4 RED LED blinks continuously (10ms ON / 2s OFF) and Node sends RF continuously 3s / time but no data. After more than 10 sending cycles, the Node will automatically reset

        Node runs dummy sending mode

        => sent by Gateway to send Downlink packets when users clear Uplink and Downlink counter values on Network Server (build in Gateway) when activated by ABP

        Configuration enabled by OTAA
        5 The RED LED flashes 10ms ON / 10s OFF and the Node does not send RF Node activation by OTAA on Network server has not been successful

        Using Margnet-Key to force Node to send RF continuously for 3 seconds / time

        => when activating by OTAA successfully, the GREEN LED will blink after sending RF
