LoRaWAN Frequency

The Milesight GS301 is a 4-in-1 LoRaWAN US915/AU915/AS923 bathroom odour detector, used to detect ammonia (NH3) and hydrogen sulfide (H2S) gas according to their electrochemical principles. The Milesight GS301 is also able to detect temperature and humidity to allow users to be fully aware of the environment of bathrooms. When the NH3 or H2S gas concentration reaches the preset threshold, the detector will trigger both LED light alarm and buzzer to notify people to ventilate the area, which is an important part of smart bathroom solutions. Apart from local alarms, GS301 can also report the sensor data and alarm messages remotely by the use of LoRaWAN® technology. Users can monitor all sensor data and control the device remotely and easily.
