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.
4-in-1 Sensors with High-Sensitivity
Integrated with ammonia (NH3), hydrogen sulfide (H2S), temperature and humidity sensors.
Detect ammonia (NH3) and hydrogen sulfide (H2S) gas according to electrochemical principle.
- NH3: ±5% Accuracy
- H2S: ±5% Accuracy
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.
