Generic 2C21 KY-003 Hall Magneticfield-Sensor module

Product description

Description: The KY-003 Hall Magnetic Sensor module is a switch that reacts to the presence of a magnetic field, turning itself on or off.

Compatible with popular microcontrolers like Arduino, Raspberry Pi and ESP32. This module offers a digital output, it looks similar to the KY-035 analog hall magnetic sensor, and it is functionally similar to the KY-024, a digital/analog magnetic sensor.

Specifications This module consists of a 3144EUA-S Hall-effect switch, a 680Ω resistor, an LED and 3 male header pins.

Operating Voltage 4.5V to 24V Operating Temperature Range 40°C to 85°C [-40°F to 185°F] Board Dimensions 18.5mm x 15mm [0.728in x 0.591in] Connection Diagram Connect the board power line (middle) and ground (-) to +5 and GND on the Arduino respectively.

Connect signal (S) to pin 3 on the Arduino.

KY-003 Arduino S Pin 3 middle +5V – GND Arduino Code The following Arduino sketch will turn on the LED on pin 13 when you put a magnet near the module.

int led = 13

//LED pin int sensor = 3

//sensor pin int val

//numeric variable void setup() { pinMode(led, OUTPUT)

//set LED pin as output pinMode(sensor, INPUT)

//set sensor pin as input } void loop() { val = digitalRead(sensor)

//Read the sensor if(val == LOW) //when magnetic field is detected, turn led on { digitalWrite(led, HIGH)

} else { digitalWrite(led, LOW)
