Linear Hall Magnetic Sensor KY-035

Description of KY-035

KY-035 is a hall magnetic sensor module that houses an AH49E linear hall effect device that is operated with the help of a magnetic source. The module varies the output voltage, which is generally set by the input supply voltage and varies in proportion to the strength of the magnetic field around the sensor.

Pin Configuration of KY-035

Below is the pin configuration of the KY-035 magnetic sensor. This pin configuration can be used when connecting the module to any microcontroller.

Features of KY-035

Here are some basic features and specifications of the magnetic sensor.

1. Supply Voltage(Vcc) – 5 V
2. Output Current (IO) – 10 mA
3. Operating Temperature – 40 to 100 Degrees Celcius
4. Can detect both the magnetic poles

Working of the KY-035

The hall effect sensor used in the KY-035 module was used in the AH49E. AH49E can detect the magnetic pole and the strength of a magnetic field. In KY-035, the module generates an analog output whenever the module comes near to a magnetic field and produces an output that can be read by a microcontroller.
If there is no magnetic field around, the analog output is generated in exactly half of the VCC.

The AH49E comes in two packages: TO-92S and SOT23-3

Connections of KY-035 with Microcontroller

The connections from the KY-035 magnetic sensor to the Arduino microcontroller are pretty simple. The module has 3 output points; Power, Ground, and Signal.

The power (5V) which is the pin in the middle, is connected to the 5V terminal of the Arduino, whereas the ground is connected to the ground terminal. The output generated is analog in nature, so it can be read through an analog pin (A0) in the Arduino.

Applications of KY-035

Here are some of the application where KY-035 magnetic sensor come into use:

1. Motor control
2. Metal detector
3. Position sensing
4. Magnetic Code Reading
5. Current sensing
