The LoRaWAN wireless transmitter is to read the measurement values from the AG sensor and performs the calculation
to deliver the desired output values, then it sends data to the gateway in the following cases:
-
Case 1: when the time of the Data sending cycle is reached.
-
Case 2: when the device is forced to send data by a Magnet key.
3.1.2 Operating principle of AG Tilt sensor
To understand how the AG Tilt sensor work, please refer to
technique.
3.1.3 Some important configuration parameters
Below are some important configuration parameters which affect the operation of the device.
measure_period | Default = 600s
This is the time period for the wireless transmitter to wake up and take the measurement from the sensor. 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
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
3.2.1 How to configure the LoRaWAN sensor?
Sensor configuration can be configured in 02 methods:
Method 1: Configuring via Downlink message. Please find the instructions in
the FW version of the Document.
Method 2: Configuring via
Note: THE SENSOR IS ONLY ACTIVE FOR OFFLINE CONFIGURATION IN THE FIRST 60 SINCE POWER UP
BY BATTERY OR PLUGGING THE CONFIGURATION CABLE.
3.2.2 What parameters of the device are configured?
Some parameters are read-only, and some are read and writeable.
To read the parameters, use the off-line cable as above instruction.
To write the parameters, use the off-line cable or downlink as above instructions.
Below tables are the lists of the parameters of the device.
