KY-020 Tilt Switch Module – Digital Orientation Sensor (Arduino Compatible)
The KY-020 Tilt Switch Module is a simple and effective way to detect movement and orientation in electronics projects. It uses an internal ball-type tilt sensor that responds when the module is angled or moved.
When positioned level, the module outputs a LOW signal. When tilted, the internal ball closes the circuit, producing a HIGH signal. This clear digital output makes it easy for students to understand and use in basic input-based projects.
Designed for compatibility with Arduino, Raspberry Pi, and similar microcontrollers, the KY-020 is ideal for introducing motion sensing and orientation concepts. It supports hands-on learning and helps students explore how physical movement can control electronic systems.
