Tilt sensor(SW-520D)

This sensor outputs a HIGH value when tilted.

It is modularized, allowing for direct connection to an Arduino.

The sensitivity of the tilt detection can be adjusted by manipulating the variable resistor on the product.

Specifications

Operating Voltage: 3.3V ~ 5V

Required Hardware

Tilt sensor
Arduino UNO
UNO Cable
M-F Cable (3 pieces)

Connection

Can be connected to a digital pin other than D7.


SW-520D	Arduino Uno
D0	D7
GND	GND
VCC	5V

Example Code

Check the execution results on the Serial Monitor. Execution video

// Define the tilt sensor pin number
#define tilt 7

void setup()
{
  // Set pin 7 as INPUT
  pinMode(tilt, INPUT);
  // Start serial communication
  Serial.begin(9600);
  Serial.println("Serial start");
}

void loop()
{
  if(digitalRead(tilt) == 0) // When the tilt sensor output is 0 (balanced state)
  {
    Serial.println("Balanced");
    delay(1000);
  }
  else if(digitalRead(tilt) == 1) // When the tilt sensor output is 1 (tilted state)
  {
    Serial.println("Tilted");
    delay(1000);
  }
}
