3pin KY-020 3.3-5V Standard Tilt Switch Sensor Module for Arduino

Description

KY-020 Tilt Switch Sensor Module for Arduino

The KY-020 Tilt Switch Sensor Module is a simple and effective device for detecting tilt, vibration, and orientation changes. With a 3-pin interface and operating voltage of 3.3V to 5V, it is fully compatible with Arduino, Raspberry Pi, and most microcontroller platforms.

This module contains a small ball inside the switch that makes or breaks contact when the sensor is tilted, producing a digital signal output. It is widely used in robotics, security systems, and DIY electronics.

How to Use the KY-020 Tilt Switch Sensor Module

1. Wiring:

   • VCC → 3.3V or 5V

   • GND → Ground

   • DO → Digital input pin (e.g., D2 on Arduino)

2. Arduino Code Example:

   int tiltPin = 2;
   int tiltState = 0;

   void setup() {
   pinMode(tiltPin, INPUT);
   Serial.begin(9600);
   }

   void loop() {
tiltState = digitalRead(tiltPin);
if (tiltState == HIGH) {
Serial.println("Tilt detected!");
} else {
Serial.println("No tilt");
}
delay(200);
}


   • When tilted, the sensor outputs a HIGH signal.

   • When stable, it outputs LOW.
