WSLRW-G4 is a LoRaWAN electrochemical-type gas sensor with a high sensitivity to low concentrations of detected gas, high selectivity, and a stable baseline. The device supports different types of gas such as CO, NO, NO2, H2S, NH3, O2, O3, SO2, Cl2, HCHO...Ultra-low Power design and smart firmware allow the sensor to last up to 5 years with a 02 x AA-type battery (depends on configuration). The sensor will transmit data at a kilo-meters distance to the LoRaWAN gateway, any brand on the market.
Typical Applications: Gas, toxic gas detecting, air quality monitoring for facility, building, pump station, HVAC...
