    Hall sensor SKU:SEN0185   Contents      1 Introduction 2 Specification 3 Pinout 4 Connection Diagram 5 Sample Code Introduction What's the best way to detect the magnet? Use anther magnet. But it's not sensitive enough. You have to feel it by youself.Right.This Hall sensor knows whether there is a magnetic object nearby or not. And it correctly tells you through ditigal output.See below picture for a quick demo! Note:It's a omnipolar magnet dectector so that it can not tell two polarities apart. Specification     Supply Voltage: 3.3V to 5V Indicator LED on board Interface: Digital Size:22x30mm Pinout 1. GND 2. VCC 3. Signal Connection Diagram Digital Hall sensor Diagram Sample Code int ledPin = 13; // choose the pin for the LED int inputPin = 2; // choose the input pin int val = 0; // variable for reading the pin status void setup() { pinMode(ledPin, OUTPUT); // declare LED as output pinMode(inputPin, INPUT); // declare pushbutton as input } void loop(){ val = digitalRead(inputPin); // read input value if (val == HIGH) { // check if the input is HIGH digitalWrite(ledPin, LOW); // turn LED OFF } else { digitalWrite(ledPin, HIGH); // turn LED ON } }                      Powered By DFRobot © 2008-2017
