Milesight VO-GS101 Gas Detector

Milesight VO-GS101, the LoRaWAN Gas Detector for Methane CH4, Semiconductor Sensor, Lower Explosive Limit 8 Vol%, Acoustic Alarm 85 dB, Alarm Output, Event Memory 800, NFC 

The Milesight VO-GS101 is the LoRaWAN gas detector for methane CH4. It reliably detects dangerous gas leaks and warns residents in time. The sensor measures methane using a semiconductor gas sensor and triggers an alarm when the lower explosive limit of only 8 Vol% is reached. The Milesight VO-GS101 is ideally suited for houses, apartments, hotels, and other buildings.

The Milesight VO-GS101 provides triple notification in case of gas leak. It emits an acoustic alarm of 85 dB, sends notifications via LoRaWAN, and displays the status through four LED indicators. In addition, it features an alarm output for connecting external devices such as gas valves or ventilation fans. The integrated buffer memory for 800 events ensures loss-free data transmission even during temporary connection interruptions.

The Milesight VO-GS101 operates with a power supply and is weatherproof with IP67 protection rating. Setup is conveniently done via an app using NFC. It comes with a power supply and mounting materials. The strong building penetration of the LoRaWAN protocol also enables reception in basements. With Milesight Cloud, you can view all events online and set up notifications if needed.

The Milesight VO-GS101 is the ideal solution for smart gas monitoring in residential and commercial spaces. It combines precise methane detection with an acoustic alarm, LoRaWAN transmission, and relay output in a compact, weatherproof housing. The battery life and simple NFC configuration ensure minimal maintenance effort.
