WSSFC-NH3 is a Sigfox-ready 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 complete Wireless and Sensor package run on 1 x AA battery 3.6V for 2-5 years with 15 minutes updates. It can support all regions of the Sigfox network over the World, RC1, RC2, & RC4.
Typical Applications: Monitor leakage of Ammonia gas for Refrigerator, Chiller...
