Description

The Milesight GS301 Bathroom Odour Detector is a four-in-one odour detector, integrated to sense ammonia (NH3), hydrogen sulphide (H2S), temperature and humidity to expand IoT technology into traditional restrooms. With its compact size, this odour detector is easy to install and maintain. The GS301 bathroom odour detector is commonly used to monitor public and office restrooms as well as sensing urinal and sewer pipes.

Alarm triggering from the GS301 includes LED lights and a buzzer to indicate changes in thresholds. This notifies anyone nearby that the concentration levels of NH3 or H2S gas are beyond acceptable levels. These alarms are a key component to creating a smart bathroom solution. The GS301 can send sensor data and alarms remotely using LoRaWAN. Users can view and monitor the sensor data through IoT Cloud software or through Milesight LoRaWAN gateways.

Built-in replaceable batteries decrease installation costs with a 3 year battery life. Power on/off and configure the bathroom detector via NFC technology from a mobile phone or PC. The Milesight D2D (Device to Device) protocol using LoRaWAN enables communication with standard gateways at a 2km communication range.
