KY-020 Standard Tilt Switch Module with digital output interface. Detects tilt or inclination and outputs a digital signal — ideal for Arduino projects requiring orientation sensing or tilt-activated alerts.

 

The KY-020 Standard Tilt Switch Module (MPN: KY-020) is a simple, reliable tilt-sensing module that outputs a digital signal when the sensor detects a change in orientation. It connects directly to a digital pin on your microcontroller and is ready to use in any project that requires tilt detection, inclination sensing, or motion-triggered responses.

Key Features

  • Digital Output Interface: Outputs a clean HIGH/LOW signal → easy to read directly with any digital pin, no ADC required
  • Built-in LED Indicator (pin 13 compatible): Use the onboard LED on pin 13 of your Arduino as a visual tilt warning indicator → instant visual feedback without extra components
  • Simple Wiring: Minimal connections needed → perfect for beginners and quick prototyping
  • Compact Module Design: Self-contained PCB with sensor and interface header → easy to mount and integrate into any project enclosure

Pinout & Wiring

PINSymbolDescription
1GNDGround
2VCCPower supply
3SDigital signal output — connect to digital pin (e.g. pin 3 on Arduino)

Wiring Note: Connect S to digital pin 3 on your Arduino, VCC to 5V, and GND to GND. The onboard LED on Arduino pin 13 will light up when a tilt event is detected.

Compatibility

  • Arduino UNO / Nano / Mega: Fully compatible — digital interface works directly at 5V logic levels
  • Other 5V microcontrollers: Compatible with any platform that reads digital HIGH/LOW signals at 5V

Typical Applications

  • Tilt warning indicator: Build a simple alarm or LED indicator that activates when an object is tilted beyond a threshold
  • Anti-theft device: Detect when a protected object is moved or tilted and trigger an alert
  • Orientation sensing in robotics: Use as a basic balance or fall detector in small robot projects
  • Learning & education: Ideal first sensor module for Arduino beginners learning digital input/output
  • Interactive installations: Trigger sounds, lights, or actions based on physical orientation changes

Frequently Asked Questions

Q: What happens when the tilt switch is triggered?
A: When the KY-020 detects a tilt, the sensor closes its circuit and the digital output goes HIGH, turning on the LED connected to pin 13 and signaling your Arduino sketch.

Q: Do I need external resistors to use this module?
A: No — the KY-020 is a self-contained module with the necessary components on the PCB, so you can connect it directly to your Arduino's digital pin without additional components.
