Milesight GS301 Bathroom Odor Detector
GS301 is a 4-in-1 LoRaWAN® bathroom odor detector that detects ammonia (NH3) and hydrogen sulfide (H2S) gas based on the electrochemical principle. The GS301 can also detect temperature and humidity to fully understand the bathroom environment. When the NH3 or H2S gas concentration reaches the preset threshold, the detector will trigger both the LED light alarm and a buzzer to notify people to ventilate in time, which is an important part of the smart bathroom solution. Besides local alarms, GS301 can also report the sensor data and alarm messages remotely using LoRaWAN ® technology. Integration with Milesight LoRaWAN
Gateway and Milesight IoT Cloud solution, users can monitor all sensor data and control the device remotely and flexibly. In addition, the GS301 supports Milesight D2D to enable ultra-low latency control without gateways.
