The sensor has 3 main components on its circuit board. First, the sensor unit at the front of the module which measures the area physically and sends an analog signal to the second unit, the amplifier. The amplifier amplifies the signal, according to the resistant value of the potentiometer, and sends the signal to the analog output of the module.
The third component is a comparator which switches the digital out and the LED if the signal falls under a specific value.
You can control the sensitivity by adjusting the potentiometer
Operating voltage: ۵ V

Weight:3g
Digital Output:
int Led=13;//define LED interface
int buttonpin=3 //Define D0 Sensor Interface
int val;//define numeric variables val
Analog Output:
int sensorPin = A5; // select the input pin for the potentiometer
int ledPin = ۱۳; // select the pin for the LED
int sensorValue = ۰; // variable to store the value coming from the sensor
