Tilt Sensor
Tilt sensors allow you to detect orientation or inclination. They are small, inexpensive, low-power and easy-to-use. If used properly, they will not wear out. Their simplicity makes them popular for toys, gadgets and appliances.
This sensors is a solution for where you need detect when something has shifted from it’s desired orientation. It’s a simple ball-in-a-sleeve that when rolled to one end closes a contact. Actually, it’s a pair of balls, the second ball reinforces the bridging of the contacts by the first ball.
In it’s simplest application, it could be hung straight down and would close only if it were swung over 90° in any orientation. Team up 2 or 3, adjust the angles, and you could have it report when orientation shifts past any one of their angles. Sort of a really poor-man’s gyro/g-force sensor.
Note: The orientation of the pins will affect the responsiveness of the sensor. Laid horizontally, the balls will bridge the sensor pins much more easily than if the pins are laid vertically.

Applications:
- To detect the position of hand-held game systems and in game controllers
- To indicate the roll of boats, vehicles and aircraft
- To measure the angle at which a satellite antenna 'looks' toward a satellite
- To estimate the height of a tree or building
- To measure the steepness of a ski slope
- To provide a warning system for the surface tilt angle of cryogenic liquids during transportation
- To monitor laser levels and seismic activity
