Multi-Network Alarm System PCBA & PCB Circuit Board

Product Details

Multi-network alarm terminal is a kind of intelligent device that can realize remote alarm through various ways, which can effectively avoid the failure of wireless alarm signal when a certain network path is sniped. It has the following structure and functions:
Sensor module: contains different types of sensors such as temperature, humidity, smoke, gas, etc., which can detect environmental parameters.
Control processing module: composed of a microcontroller and a communication module, it can collect sensor data periodically and determine whether to trigger alarm conditions.
Communication module: The use of WiFi, GPRS, shortwave, telephone, mail, Beidou and other ways to achieve the connection with the Internet, the alarm information sent to the cloud service or control center.
Alarm output module: contains buzzer, trigger, etc., when detecting alarm conditions, sound, light and other alarm prompts.
Power module: Supplies power for each component.
The working principle is:
The sensor monitors the environment in real time or the artificial alarm is triggered, such as the detection of gas concentration, temperature, etc. exceeds the threshold, the control processing module determines the trigger alarm conditions, and sends alarm information through the communication module. At the same time, activate the alarm output for sound and light alarm. The control center that receives the alarm information can carry out further response and processing.
The device can be widely used in homes, factories, storage rooms and other places to achieve remote environmental monitoring and safety early warning.
