Description

The GS301-868M from Milesight is a LoRaWAN ammonia detection sensor with which you can measure both Ammonia (NH3) and Hydrogen sulfide (H2S).

The sensor is equipped with ammonia (NH3), hydrogen sulfide (H2S), temperature and humidity sensors. The ammonia and hydrogen sulfide values are detected using an electrochemical principle with an accuracy of 5%.

When the ammonia or hydrogen sulfide concentration reaches the threshold, the sensor gives an LED indication and an uplink is sent.

The threshold values are adjustable. It is also possible to directly switch an HVAC system based on the detected concentrations of ammonia and hydrogen sulfide produced from the urinal and the sewer pipe.

The odour detector is compact in size and easy to install and maintain. With its moisture-resistant coating, the detector can operate under various conditions in bathrooms

As standard, the GS301 is supplied with batteries, mounting kit and 2-year warranty.
