Introduction
The DFRobot Tilt Sensor is a digital mercury-based tilt switch that is either closed, disconnected or open. The module is based on a series of mercury switches. The mercury flows to the low-lying pressure and could therefore be used as a simple tilt sensor. in combination with our dedicated Arduino sensor expansion boards , this sensor can be used in any interactive project with easy plug and play features!
NOTE: Mercury is a toxic substance, please be careful to avoid breaking the glass case.

Connection Diagram
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
}
}
