| Digital magnetic sensor SKU DFR0033 Contents • 1 Introduction • 2 Specification • 3 Connection Diagram • 4 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 magnetic 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! Specification • Supply Voltage 3.3V to 5V • Indicator LED on board • Interface Digital • Size:22x30mm Connection 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 |
