introduction
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
GND - GND
S - Digital pin3
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
}
}
