GS301 LoRaWAN Bathroom Odor Detector

GS301 is a 4-in-1 LoRaWAN bathroom odor detector to detect ammonia (NH3) and hydrogen sulfide (H2S) gas according to electrochemical principle. GS301 is also able to detect temperature and humidity to fully aware of the environment of bathrooms. When the NH3or H2S gas concentration reaches the preset threshold, the detector will trigger both LED light alarm and buzzer to notify people timely to ventilate, which is an important part in smart bathroom solution. Apart from local alarms, GS301 can also report the sensor data and alarm messages remotely by the use of LoRaWAN technology. Integrating with Milesight LoRaWAN gateway and Milesight IoT Cloud solution, users can monitor all the sensor data and control the device remotely and flexibly. Moreover, GS301 supports Milesight D2D to enable ultra-low latency control without gateways.

Minimalist &
Practical Design

GS301 LoRaWAN Bathroom Odor Detector is compact in size and easy to install and maintain. With damp proof coating, the detector can work on various conditions of bathrooms.

Stay Informed of Foul Air

When ammonia or hydrogen sulfide concentration reaches thresholds, the alarm will be activated, including traffic lights indicator, built-in buzzer and uplink data packets. *Thresholds can be customized

Assistant to Ventilator
for Clearer Air

HVAC system is empowered to automatically adjust based on the detected concentrations of ammonia and hydrogen sulfide produced from the urinal and sewer pipe.

Milesight D2D
Featuring LoRa®

Support Milesight D2D protocol to enable ultra-low latency and direct ventilation control without gateways.

Lower Latency
