NETVOX Wireless Sensor R718X is a LoRaWAN Class A device and it is compatible with LoRaWAN protocol.

R718X has a built-in ultrasonic ranging sensor that can detect the distance from the sensor to the detected object (for example: detect the height of garbage in the waste bin).

R718X also has the temperature detection function, it can detect the temperature of the waste bin. R718X would send out the detected data through wireless network.


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

  • Waste bin fill-level detection 
  • Others
