- Interfacing Knock / Tap / Vibration Sensor with Arduino:
-----------------------------------------------------------------
COMPONENTS REQUIRED:
Arduino UNO
Knock Sensor Module
1KΩ Resistor
LED
-----------------------------------------------------------------
CONNECTIONS:
The design of the circuit for Arduino Knock Sensor interface is very simple. Connect the Supply and GND pins of the Knock Sensor to +5V and GND pins of Arduino.
Then connect the OUT (S) pin of the sensor to Digital I/O pin 8 of Arduino UNO. Finally, an LED is connected to Pin 7 of Arduino UNO through a 1KΩ current limiting resistor.
-----------------------------------------------------------------
WORKING:
Make the connections as per the circuit diagram and upload the code to Arduino. Fix the knock sensor to a door and knock on the door.
If the vibrations are sufficient enough for the sensor to detect, the OUT of the sensor becomes low for that moment. This is detected by Arduino and it turns ON the LED for a second.
-----------------------------------------------------------------
APPLICATIONS
The main purpose of the Knock Sensor is to detect vibrations or shocks. Hence, the main application of such sensor can be in Door Knock System, where when a door is knocked, a notifications (like a light or a buzzer) can be activated.
