| 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 GND VCC 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 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 |
