Natural gas, used e.g. in gas stoves, is a colorless gas, barely noticeable. It is lighter than air, so it accumulates in the upper parts of rooms. When combined with oxygen, it creates a highly explosive mixture. Propane-butane gas (LPG) is heavier than air, just like natural gas, it forms an explosive mixture with oxygen. Installing gas sensors in rooms where gas installation leaks may occur is a way to early detect the risk of gas explosion.
The SN051 gas sensor is used to continuously monitor the presence of explosive gases (natural and propane-butane) in the air. If an increased gas concentration is detected (approx. 10% LEL*), the device activates an audible and optical alarm, enabling the user to react early enough to prevent an explosion or poisoning. The device is equipped with an advanced semiconductor sensor and an electronic self-diagnostic system that indicates sensor damage.
433MHz RF function
Works with alarm systems, wireless sirens in EV1527 433.92 MHz coding. Popular Alarm Systems
Set your alarm device to pairing mode, then press the TEST button on the device. The gas sensor will send a unique RF433 MHz code. Your alarm device should receive and save the detector’s radio code.
The device is compatible with Sonoff, Sonoff Bridge, PG and Digoo Alarm Systems from our offer.
