Deviteq / Wireless Sensors and Actuators / IOT Solution - LORAWAN AMMONIA NH3 GAS SENSOR

Deviteq / Wireless Sensors and Actuators / IOT Solution – LORAWAN AMMONIA NH3 GAS SENSOR

WSLRW-NH3 is a LoRaWAN electrochemical-type gas sensor that has a high sensitivity to low concentrations of ammonia gas, high selectivity, and a stable baseline. With Ultra-low Power design and smart firmware allow the sensor can last up to 10 years with a 02 x AA-type battery (depends on configuration). The sensor will transmit data in a kilo-meters distance to the LoRaWAN gateway, any brand on the market.

Typical Applications: Monitor leakage of Ammonia gas for Refrigerator, Chiller…

LoRaWAN communication

  • LoRaWAN communication standard to allow sensor connect to any LoRaWAN Gateway on the market

Ultra-low power with 5 years battery

  • Ultra-low power sensing technology from Daviteq with Ultra-low power wireless technology allow the sensor can last up to 5 years with 02 x AA batteries

High Accuracy & Stable

  • Advanced electrochemical-type gas sensor technology processing to deliver high accuracy and stable measurement
