Description
This Arduino compatible knock sensor module can detect knocks and impacts. It can work as a switch. It can be used to build a simple LED circuit that lights up when an impact is detected. It has potential applications wherever you might want your project to respond to sudden impacts for safety purposes or simply as a unique input method.
This knock module consists of a 10 kΩ resistor and a spring-based sensor that sends a high signal when a vibration is detected.
Note: If your project requires a more sensitive module, see the ARD2-2202.
Test Code
int Led = 13; // define LED Interface
int Shock = 3; // define the percussion Sensor Interface
int val; // define numeric variables val
void setup () {
pinMode(Led, OUTPUT); // define LED as output interface
pinMode(Shock, INPUT); // define knock sensor output interface
}
void loop () {
val = digitalRead(Shock); // read digital interface is assigned a value of 3 val
// When the percussion when the sensor detects a signal, LED flashes
if (val == HIGH) {
digitalWrite(Led, LOW);
}
else {
digitalWrite (Led, HIGH);
}
}
Features
- Make an external LED light up when the sensor detects a knock/impact
- Add a unique input to your project or respond to sudden impacts as a safety feature
