When the tilt sensor is in its upright position, the ball inside the tilt sensor bridges the two contacts, completing the circuit. When the board is tilted, the ball moves, and the circuit opens. When ...

Expanding on the ‘ball in a tube’ construction of simple tilt sensors, he designed a laser cut 3D tilt sensor that does all the work of of a $30 IMU.

Researchers at Yokohama National University have created a liquid-based tilt sensor that only needs simple interface electronics – some 10MΩ resistors and a Microchip ATmega microcontroller in the ...
