Description

The Milesight GS301 is a specialized 4-in-1 LoRaWAN Odor Detector engineered for smart bathroom solutions in commercial buildings, hotels, and public facilities. Utilizing high-accuracy electrochemical sensors, it monitors concentrations of Ammonia (NH3) and Hydrogen Sulfide (H2S), the primary markers of restroom odors. When thresholds are breached, the device triggers an integrated LED and buzzer to notify staff, while simultaneously transmitting data over LoRaWAN. Crucially, the GS301 supports the Milesight D2D protocol, enabling it to act as a controller that can directly trigger ventilation fans or air purifiers in under a second without relying on a gateway or cloud network.

Advanced Air Quality Intelligence

Milesight D2D Control Achieve ultra-low latency automation by linking the GS301 directly to D2D agents like smart switches or valves for immediate odor mitigation.
Long-Life Sensor Design Features electrochemical sensing technology with over 3 years of life expectancy and internal damp-proof coating for high-humidity environments.

Smart Facility Scenarios

• Commercial Restrooms: Maintain high hygiene standards by automating ventilation and cleaning schedules based on gas levels.
• Hotel Hospitality: Ensure guest comfort with 24/7 odor monitoring and instant alerts for maintenance personnel.
• Public Infrastructure: Monitor public toilets in parks or stations to optimize janitorial services and operational costs.
