Introduction

The DFRobot Tilt Sensor is a digital mercury-based tilt switch that is either closed, disconnected or open. The module is based on the number of mercury switches. The mercury flows to the low-lying and could therefore be used as a simple tilt sensor. The dedicated sensor expansion boards with the Arduino, in combination, can achieve very interesting and an interactive work.

Sample Code


int ledPin = 13;                // Connect LED to pin 13
int switcher = 3;                 // Connect Tilt sensor to Pin3

void setup()
{
  pinMode(ledPin, OUTPUT);      // Set digital pin 13 to output mode
  pinMode(switcher, INPUT);       // Set digital pin 3 to input mode
}
void loop()
{

   if(digitalRead(switcher)==HIGH) //Read sensor value
     {
        digitalWrite(ledPin, HIGH);   // Turn on LED when the sensor is tilted
     }
   else
     {
        digitalWrite(ledPin, LOW);    // Turn off LED when the sensor is not triggered
     }
}
