Description

Wired proximity sensor activated magnetically. The device is used to determine the position of doors and windows. The principle of operation is similar as in a traditional relay. The circuit is open by default, when approaching the magnet, circuit is being closed, which means that through the wires, the current begins to flow.

Connection

The sensor can be easily connected to any cip with a microcontroller, e.g.an Arduino. By attaching a pulling up resistor or by running an internal pull-up, the read can be implemented in digital form.

 

Communication with Arduino

To verify that the functionality of the sensor, use the attached to theArduinoprogram - DigitalInputPullup, which is in the menu:File -> Examples -> Digital. It is sufficient to connect one sensor's wire to ground GND, the other to the pin No. 2 ofArduino, and when bringing together both parts of the sensor, the built-in L led connected to pin 13, will light up.
