Description

KY-035 is an analog magnetic field sensor module. 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.

KY-035 Class Bihor Analog Magnetic Sensor Connection

• 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
