Mini tilt sensor for Arduino and microcontroller boards [sensor]

This is the first proto pcb finished. It's simple. This device detects movement. It only has two components, the tilt sensor, very very sensitive, almost detects when you blow and two connector pins. This prototype pcb has a hole in order to fix it in any surface.

This mini tilt sensor can be connected easily using wires. You can put the sensor close or far from the electronic system. You can connect this to any Arduino or microcontroller board or any other computer system to detect the slightest movement. At rest, the pins are closed (connected). When some movement is detected, the pins are changing opening and closing while movement still active. It can be mounted in any position (omnidirectional). 

Dimensions: 23,2mm (including pins) x 1,2mm. Hole diameter 0,3mm. Cost: 9€.
