Product Description

The Milesight GS101 is a LoRaWAN® residential gas detector designed to detect natural gas leaks and send alarms. This device is crucial for home safety, as it can identify gas leaks and take immediate action to prevent potential accidents. When the gas concentration reaches a preset threshold, the GS101 triggers both LED light and buzzer sound alarms. It also supports controlling outputs to close the gas valve and open vent fans, enhancing safety measures in residential spaces.

Apart from local alarms, the GS101 can report the normal status of the device and alarm messages remotely via LoRaWAN® technology. This feature allows integration with Milesight LoRaWAN® gateways and the Milesight IoT Cloud solution, enabling users to monitor sensor data and control the device remotely and visually.
