R718DA2 – Wireless LoRaWAN 2-Gang Vibration Sensor Rolling Ball Type
R718DA2 is equipped with two external rolling ball-type vibration sensors. When either of the vibration sensors moves or vibrates, R718DA2 can detect vibration or moving signals and send an alert to the data center through LoRaWAN™.
R718DA2 – Wireless 2-Gang Vibration Sensor Rolling Ball Type is fully compatible with LoRaWAN™ protocol (Class A).
Features
*1. Actual range may vary depending on environment.
*2. Battery life is determined by sensor reporting frequency and other variables
