In the smart home market, household gas sensors have become a necessity in the design of smart homes. The penetration rate in foreign countries has reached more than 85%, and China is also popularizing it. The gas sensor is generally installed in the kitchen, and its sensor (commonly known as “electronic nose”) will change with the gas concentration, and then generate an electrical signal, and emit an audible and visual alarm signal.
With the development and maturity of wireless transmission technology, wireless sensors Module products began to gradually penetrate into all aspects of the smart home field with their own unique advantages, becoming an emerging hot spot in the market. Shengrun Technology Home Gas Detection Module (Bluetooth Edition) uses a catalytic combustion sensor with the basic functions of a domestic gas leak alarm. In addition to the traditional sound and light alarm through LED and buzzer, it can also support APP, gateway, background, linkage, and remote alarm.

Module working status description
1, Preheating status: The main board indicator flashes three times and the buzzer sounds three times. The small board indicator flashes slowly. After 3 minutes, the warm-up status indicator is always on;
2, Alarm status: When the ambient gas concentration reaches the alarm setting of the module After the value, the main board indicator flashes three times, and the buzzer sounds three times. If the alarm status continues, the loop will be activated, and the small board indicator will flash quickly;
3, Normal Working status: The main board indicator is off, the buzzer stops sounding, and the small board indicator is always on;
4, Fault status: When the sensor is faulty, The main board indicator is off and the small board indicator is off.
In recent years, with the rapid development of the Internet and the Internet of Things, the application of sensors in smart homes has advanced by leaps and bounds, greatly expanding the application space, and the demand has also changed by orders of magnitude. Perhaps in the near future, smart homes will enter every household, smart homes will have built-in sensors, combined with gateway operation, so that home devices can better cooperate, so that home products are all intelligent.
