HS-S40-L霍尔磁性传感器

1. Introduction

Hall magnetic sensors are a type of magnetic field sensor made based on the Hall effect.The full-potential Hall effect is a type of magneto-electric effect.When the magnet approaches its sprinting surface, the switch outputs a low level; when the magnet is removed, the switch outputs a high level.

2. Schematic

Module Parameters

• Power Supply Voltage: 3.3V / 5V

• Connection method: PH2.0 3P terminal

• Installation Method: Double Screw Fixed

5 of Arduino IDE example program

Arduino UNO Example (for Mixly IDE, Arduino IDE):

volatile int value;

void setup(){
  Serial.begin(9600);
  value = 0;
  pinMode(5, INPUT);
  pinMode(6, OUTPUT);
}

void loop(){
  value = digitalRead(5);
  Serial.print("串口值：");
  Serial.println(value);
  delay(1000);
  if (digitalRead(5) == 0) {
    digitalWrite(6,HIGH);

  } else {
    digitalWrite(6,LOW);

  }

}

ESP32 Python Example (for Mixly IDE / Micskit)
(Choose the Python ESP32 [ESP32 Generic(4MB)] to switch to code mode upload):

import machine


pin2 = machine.Pin(2, machine.Pin.IN)
pin4 = machine.Pin(4, machine.Pin.OUT)
value = 0
while True:
value = pin2.value()
print(value)
if pin2.value() == 0:
pin4.value(1)
else:
pin4.value(0)
