Arduino Mercury Switch Breakout Module

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.

Pin definition

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 
    } 
}
