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
* It is highly recommended that sensors operate below 35°C.
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
- Less than 1 Second Response Time
- Secure Transmission
- Reduce Investment Cost
*When Milesight D2D is enabled, LoRaWAN® protocol can operate as usual.
Multi-Year Battery
Operation
Built-in 4 x 4000 mAh ER18505 Li-SOCL2 batteries ensure up to 3 years' service life.
