Description:

Analogue output Hall Effect (magnetic field) sensor module using a SS49E Linear Hall Effect Sensor

KY-035 is an analog magnetic field sensor module. The strength of the field is given by an analog voltage at the signal pin of the module KY-035. The sensor is connected to gnd and 5V of the Arduino board. The output voltage is measured by analog pin A5 on the Arduino board.

The example program measures the output voltage of the sensor en presents the measured value in the serial monitor of the Arduino.

The led on the board flashes in a speed depending on the strength of the magnetic field. With a small magnet this can be demonstrated.

Supply: 4 - 6.5V DC 

Connecting to the Arduino

  • Pin - = GND, connect to GND of the Arduino
  • Pin (middle pin) +5 V, connect to Arduino +5 V
  • Pin S signal, connect to Arduino pin A5
  • Power consumption sensor, 8 mA

Example Code

 
int sensorPin = A5;    // set the sensor signal pin
int ledPin = 13;       // set the LED pin
int sensorValue = 0;   // variable to store the value from the sensor
 
void setup () {
  pinMode (ledPin, OUTPUT);
  Serial.begin (9600);
}
 
void loop () {
  sensorValue = analogRead (sensorPin);
  digitalWrite (ledPin, HIGH);
  delay (sensorValue);
  digitalWrite (ledPin, LOW);
  delay (sensorValue);
  Serial.println (sensorValue, DEC);
}

Remove sensor from PCB to get full Voltage output swing.

I can only get from 3.5V to 4.5V signal output from the hall sensors.
I removed the sensor from the PCB and connected it like in this datasheet: https://pdf1.alldatasheet.com/datasheet-pdf/view/473135/SECELECTRONICS/SS49E.html Now get close to the full 5V swing from the sensor. .... If any of you have the same issue..... I did not bother to look for the issue on the PCB's....
