RA0701-Wireless CO Sensor

   

RA0701 is a wireless communication device that detects the carbon monoxide content in ambient air. RA0701 can detect the concentration of CO in the air. The body and the sensor are connected through the RS485 interface, and the detected data is transmitted to data center through the wireless network for display. It adopts the wireless communication method conforming to the LoRaTM protocol standard.
