NETVOX Wireless Sensor R718PB13 is a ClassA type device based on the LoRaWAN protocol.

The R718PB13 is connected to the EC-5 soil sensor, and the soil moisture collected by the sensor is reported to the corresponding gateway

Principle of Operation

NETVOX Wireless Temperature Sensor outputs the ambient temperature in degrees Celsius. It is programmed to sleep for a user-given time interval (heartbeat) and then wakeup. To stay within the abilities of the processor, the temperature is computed off a data table provided by the manufacturer.

Example Applications

Soil moisture content detection
