WSSFC-G4F-NH3 is a Sigfox-ready sensor with a built-in advanced gas sensor to measure the concentration of Ammonia NH3 and H2S to help assess odors in the Toilet. With a special design that increases the sensitivity of the sensor, even though it is mounted on the ceiling at a distance of up to 2.6m. The sensor has an ultra-low-power design and smart firmware that allows the sensor to run on 2 x 1.5VDC AA batteries for 2-5 years with 15 minutes of updating. The sensor supports Sigfox network regions of the world, RC1, RC2, and RC4.
Typical application: Odor monitoring in private or public restrooms, toilets, and WC, helps to manage optimal cleaning staff.
