The Tilt sensor is a digital mercury-based tilt sensor which allows you to detect orientation and inclination. It acts like a switch. When the tilt sensor is in horizontal position, it’s open. When tilt, the switch closed and pass current.

==Note==
Mercury is toxic substance, Please be careful to avoid breaking the case.

==Features==
They are small, inexpensive, low-power and easy to use. Their simplicity make them popular for toy , gadget and appliances and many other application.

==Usage==

VCC - 5V<br>
GND - GND<br>
S   - Digital pin3<br>

==Example 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 
     } 
}
