Reed switch is a kind of passive electronic switching component with contacts with a simple structure, small size and easy to control. 
A Reed Switch Module is a magnetic sensor that is normally open and gets closed when exposed to a magnetic field. The reed switch must work together with the magnet, when it detects magnetism, then the circuit connects and the module outputs a low level; when there is no magnetic force it is disconnected and the module outputs a high level.
