LORAWAN NH3 AND H2S SENSOR FOR TOILET ODOR
SKU: WSLRW-G4F-NH3
WSLRW-G4F-NH3 is a LoRaWAN sensor with a built-in advanced gas sensor to measure the concentration of Ammonia NH3 and H2S to help assess odors in the Toilet. A special design increases the sensor's sensitivity, 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 all LoRaWAN frequency bands on over the World.
Typical application: Odor monitoring in private or public restrooms, toilets, and WC, helps to manage optimal cleaning staff.
High Sensitivity
- Special design to get high sensitivity even the sensor is mounted on ceiling up to 2.6m
Anti-tampering
- Allow mounting the sensor on ceiling or high wall to prevent tampering
LoRaWAN compliance
- LoRaWAN Class A, V1.0.3, all frequency bands
Ultra-low-power Design
- Allow the sensor to run in 2-5 years with 2 x AA batteries
