DIYables SW520D Tilt Angle Sensor Module Ball Switch LM393 for Arduino ESP32 ESP8266 Raspberry Pi, Adjustable Sensitivity, 5 Pack
Click to zoom
Quick Overview
The DIYables SW520D Tilt Angle Sensor Module uses the SW520D ball switch to detect tilt and angle changes, outputting a clean digital signal through an LM393 comparator. When the module tilts beyond the trigger threshold, the ball switch closes and the LM393 outputs a logic-level signal readable by Arduino, ESP32, ESP8266, Raspberry Pi, or any 3.3V–5V digital input.
An onboard potentiometer lets you adjust the trigger sensitivity to suit different tilt angles and applications without modifying your code. The module includes a power LED and a separate output indicator LED so you can visually confirm both power status and trigger events during setup and testing. Mounting holes are provided for permanent installation.
Ideal for tilt detection, anti-theft alarms, orientation sensing, safety cutoffs, and motion-triggered projects on Arduino, ESP32, ESP8266, and Raspberry Pi.
