Tilt Sensor

Z2M Part: EMS-00021-A

Detect tilt or orientation with tilt sensor.

Circuit Diagram

Wire Connections & Pin Configuration

Wire Color Connections:

Yellow → Digital Pin 2 to Tilt sensor (one leg)
Black → GND to Tilt sensor (other leg)

Pin Configuration:

Arduino Digital Pin 2 → Tilt sensor (one leg)
Arduino GND → Tilt sensor (other leg)

Arduino Code

Edit

const int LED = 13;  // LED connected to pin 13
const int Tilt = 2;  // Tilt sensor connected to pin 2
int val = 0;         // Variable to store sensor value

void setup() {
  pinMode(LED, OUTPUT);  // Set LED pin as output
  pinMode(Tilt, INPUT);  // Set tilt sensor pin as input
  Serial.begin(9600);    // Initialize Serial Monitor
}

void loop() {
  val = digitalRead(Tilt);  // Read digital value from tilt sensor
  Serial.println(val);      // Print sensor value to Serial Monitor

  if (val == HIGH) {        // If tilt is detected
    digitalWrite(LED, HIGH); // Turn ON LED
  } else {
    digitalWrite(LED, LOW);  // Turn OFF LED
  }
}

Instruction Details

Wiring: Connect tilt sensor one leg to Digital Pin 2, other leg to GND. Internal pull-up enabled in code.
Library: Not required (built-in).
Upload Code: Tools → Board → Arduino Uno. Tools → Port → select your COM port. Click Upload button.
View Output: LED (Pin 13) turns ON when sensor tilted. Open Serial Monitor at 9600 baud to see 0/1 values. Tilt sensor to test.
