## Long description

The Milesight GS301-868M Bathroom Odor Detector is a LoRaWAN-enabled sensor designed to monitor restroom air quality by measuring ammonia (NH3) and hydrogen sulfide (H2S) concentrations. Intended for continuous operation, the device provides regular readings suitable for integration with IoT platforms and building management systems. With wireless connectivity and compact design, the GS301-868M supports automated ventilation control, cleaning triggers, and historical analysis of odor events to help maintain hygienic restroom environments.
Advantages
The GS301-868M offers remote, real-time monitoring of NH3 and H2S without the need for wired connections, reducing installation complexity in restroom facilities. Its LoRaWAN communication enables long-range, low-power data transmission to gateways and cloud platforms. Continuous measurements enable timely activation of ventilation systems or cleaning workflows and provide data for trend analysis and reporting. The sensor's compact footprint and weather-resistant enclosure simplify placement in stalls, corridors, or service rooms while minimizing visual impact.
Suitable for
Public restrooms in malls, airports, and train stations
Office building and workplace restroom monitoring
Hospitality facilities such as hotels and restaurants
Industrial welfare areas and staff bathrooms
Facilities management systems requiring odor or gas level alerts
Key specifications
Sensing gases: ammonia (NH3) and hydrogen sulfide (H2S)
Connectivity: LoRaWAN (868 MHz band)
Power: low-power design suitable for battery operation or mains with appropriate adapter
Operation mode: continuous periodic measurements with configurable reporting intervals
Enclosure: compact, wall-mountable housing suitable for indoor restroom environments
Data integration: designed for seamless data forwarding to LoRaWAN networks and IoT platforms for alerts and historical analysis
How to use
Install the GS301-868M on a wall or partition at breathing height in the area to be monitored, avoiding direct airflow from vents or open windows that could skew readings. Commission the device by connecting it to a LoRaWAN gateway and registering it in your network server or IoT platform. Configure measurement frequency and threshold values for NH3 and H2S according to facility requirements; default settings provide periodic updates while conserving power. Validate sensor operation by observing initial readings in the platform and adjust placement or reporting intervals as needed for reliable coverage.
Usage recommendations
For consistent measurements, place the detector away from direct air vents and cleaning chemical storage. Establish threshold-based alerts that trigger ventilation or cleaning tasks, and schedule periodic calibration or verification according to facility maintenance procedures to maintain sensor accuracy over time.
