Tilt sensors are essential components in security ... through the DC IN /USB socket of the Arduino board. Keep the tilt switch position in upright position as indicated in the figure shown below.

The RB-4G0124 and RB-231 series of rolling-ball tilt switches feature a funnel-shaped design for high accuracy and 360° detection. Targeting use in safety-control applications, such as irons, portable ...

The DSA01 combination tilt/sensor switch, which is triggered when tilted beyond ±10° of the horizontal axis, is said to be extremely sensitive to small angle changes.

This project uses a Raspberry Pi 2 or 3, an Arduino Uno, some servos, and a USB webcam. The end result is a camera mounted to the servo that’s controlled by the Arduino.
