HS-S27A Four-Way Tilt Sensor Module - Digital Output, 3.3V/5V Compatible
The HS-S27A is a digital four-way tilt sensor module featuring a steel ball switch mechanism, providing a simple HIGH/LOW output signal upon tilt detection. Operating from 3.3V to 5V DC, it is directly compatible with Arduino, ESP32, and other microcontroller platforms via its standard 3-pin interface for straightforward integration into motion-sensing projects.
Features
- Four-way digital tilt detection via internal steel ball switch mechanism.
- Outputs a clean digital HIGH/LOW signal (low on tilt, high at rest).
- Wide operating voltage range of 3.3V to 5.5V for flexible system integration.
- Standard 2.54mm 3-pin interface (VCC, GND, Signal) for plug-and-play connectivity.
- Compact PCB design (36mm x 21mm) with dual mounting holes for secure installation.

The HS-S27A tilt sensor module operates on a fundamental electromechanical principle. A conductive steel ball inside the sealed switch makes or breaks contact with internal metal terminals based on its orientation. When the module is tilted beyond its activation threshold, the ball rolls to close the circuit, pulling the digital output pin to a logic low state. In its resting, level position, the circuit remains open, and the output pin is held high by an internal pull-up resistor.
This digital output provides a simple, real-time indication of tilt or vibration, making it ideal for state detection rather than precise angle measurement. The module includes signal conditioning circuitry for a clean, bounce-free digital signal compatible with 3.3V and 5V logic microcontrollers. Its robust construction and straightforward interface facilitate rapid prototyping and integration into security systems, robotics, and orientation-sensitive devices.
