Milesight GS301-915M GS301 LoRaWAN IoT Bathroom Odour Detector

The Milesight GS301 is a 4-in-1 LoRaWAN US915/AU915/AS923 IoT bathroom odour detector, used to detect ammonia (NH3) and hydrogen sulfide (H2S) gas according to their electrochemical principles. The Milesight GS301 is also able to detect temperature and humidity to allow users to be fully aware of the environment of bathrooms. When the NH3 or H2S gas concentration reaches the preset threshold, the detector will trigger both LED light alarm and buzzer to notify people to ventilate the area, which is an important part of smart bathroom solutions. Apart from local alarms, GS301 can also report the sensor data and alarm messages remotely by the use of LoRaWAN® technology. Integrating with Milesight LoRaWAN® gateways and Milesight IoT's Cloud solution, users can monitor all sensor data and control the device remotely and easily. Moreover, the GS301 supports Milesight D2D (Device 2 Device) to enable ultra-low latency control without gateways. This sensor is also compatible with Scopious IoT.

- Built-in high accuracy electrochemical gas detection sensor with more than a 3-year life expectancy
- Supports LoRaWAN IoT US915/AU915/AS923-1&2&3&4
- Built-in multiple sensors including NH3, H2S, temperature and humidity
- Built-in batteries to achieve wireless power supply and decrease the installation cost
- Equipped with buzzer and LED indicator to indicate threshold alarms
- Damp proof coating inside the device to ensure device will work well in various conditions
- Supports Milesight's D2D protocol to enable ultra-low latency and direct ventilation control without gateways
- Built-in NFC for easy configuration
- Compatible with standard LoRaWAN® gateways and network servers
