This is a ZigBee+RF433 transmission gas alarm. When the alarm detects that the gas in the surrounding environment reaches a 30% LEL alarm concentration value, the alarm will trigger the following reactions based on the model: emitting an alarm sound, sending an alarm code wirelessly, closing the solenoid valve, and remotely pushing alarm information through the APP; When the gas concentration in the surrounding environment returns to 0%, the LEL alarm will stop and automatically return to normal monitoring status.
