App alarm reminder: intelligent detection of various types of gas leaks (such as petroleum gas, natural gas, methane), when there is a gas leak, it will send a message to the mobile phone to remind you to reduce accidents. High temperature alarm: When the temperature around the detector rises to the preset value, the red alarm indicator flashes, the value ring is displayed on the screen, and a prompt tone of "high temperature alarm. Check immediately" is issued, and the mobile phone will receive the same SMS notification. When a gas leak is detected, the liquid level ring is displayed and a sound of "there is a gas leak, check immediately" is issued. When the gas leakage level continues to rise and reaches the preset value, the detector will sound an alarm and the red alarm indicator will flash. The detector can be connected to external devices such as solenoid valves and exhaust fans. After the alarm occurs, the device will be automatically controlled to reduce potential dangers. Application scenarios: The device has high sensitivity and quick response, and can accurately measure low-concentration smoke. It is suitable for homes, office buildings, factories, schools, hotels, warehouses, entertainment venues, trains and other places.
