After that, Sigfox node will send the first message to 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;
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.
5. Operation Principle
Upon power on, the Sigfox node has 60 seconds to wait for off-line configuration (via cable with ModbusRTU
protocol).
NOTE:
Once sending the data to base station by this alarm event, the timer of sending time interval will be reset;
