The circuit is a true transistor based design. Home made Tilt sensor for this circuit is an ordinary little glass/plastic bottle with two metal needles inserted through its cap, and a small quantity ...

He had the idea to create a simple tilt sensor based circuit that would light whatever LED was at the bottom. ... motion. Two of these would make a great non micro tilt sensor.

An inclination or tilt sensor provides angular-tilt information relative to gravitational force. This information can then be used to change the characteristics of the device ...

Yet, the sensor responsible for measuring such critical information requires complex external circuits and its internal mechanisms can drift over time, resulting in an accumulation of errors.
