Robotdyn® Hall Effect Magnetic Sensor with Analog & Digital Output Module

Feature The Hall Effect Magnetic Sensor can be used for detect the presence or absence of nearby objects such as magnets If no magnetic field is present the signal line of the sensor is HIGH on digital out If a magnetic field is presented to the sensor the signal line goes LOW on digital out at the same time the LED blue on the sensor lights up The distance detection to a magnetic object can be adjusted via the potentiometer on board It also has the Analog output to determine the large of a magnetic field or the distance to an object The polarity of the magnetic field is of influence to the switching action The front side of the sensor needs the opposite polarity as the back of the sensor to switch on Connection GND to GNDVCC to 5VDO to any Digital P OAO to any Analog InDocuments Dimensional drawing Click here to openPinout Click here to openSchematic Click here to open Package includes 1 x Hall Effect Magnetic SensorSketch Arduino define SENSOR 3 define the Hall magnetic sensor Digital I O define LED 13 LED D13void setup pinMode LED OUTPUT LED on D13 pinMode SENSOR INPUT Hall magnetic sensor on D3 void loop if digitalRead SENSOR LOW read seonsor and when the Hall sensor detects a magnetic field Arduino LED lights up digitalWrite Led HIGH digitalWrite Led LOW
