KY-017 MERCURY TILT SWITCH MODULE
Short description :
The KY-017 Mercury Tilt Switch module is a switch that responds to movement. It uses a small mercury ball that completes the circuit when the module is tilted.
Working with (Compatible)
Arduino, ESP32, Nodemcu, ESP8266, Raspberry Pi, and ......
ARDUINO IDE CODE
Example description :
The following sketch will light up the led when the module is tilted.
int led_pin = 13; // Define the LED interface
int switch_pin = 3; // Definition of mercury tilt switch sensor interface
int val; // Defines a numeric variable
void setup()
{
pinMode(led_pin, OUTPUT);
pinMode(switch_pin, INPUT);
}
void loop()
{
val = digitalRead(switch_pin); // check mercury switch state
if(val == HIGH)
{
digitalWrite(led_pin, HIGH);
}
else
{
digitalWrite(led_pin, LOW);
}
}
