This project is based on the module, laser module, a buzzer, and a push button, the idea is very simple, the laser is constantly projecting light to the module sensor, when a person or something ...

[over9k] used his Arduino to set up a laser trip wire.The laser is mounted along side the Arduino, reflects off of a mirror, and shines on a photoresistor that interfaces via a voltage divider.

Interfacing PM2005 and Arduino is easy, though no Arduino Shield is available. The PM2005 needs 4 wires (GND, 5V, RX, TX). A good 5V supply of between 4.9V and 5.1V is necessary. With an only ...
