KY-024 Linear Magnetic Hall Effect Sensor is a small, versatile, linear unipolar hall-effect sensor board that can act as a magnetic switch or simply measuring the strength of the magnetic field present. This hall effect sensor module works on hall effect principle so, it is more sensitive to magnetic flux and suitable for harsh environment because of semiconductor type casing and no glass encapsulation. This can work as both analog and digital unipolar hall effect sensor, it changes its state if one pole of magnet comes near it which can be easily read by any Digital GPIO pin on the Microcontroller board like Arduino, Raspberry Pi, Beagle bone Black, if is working in Digital Mode or you can connect the Analog output to any ADC and see the strength of the magnetic field present. This is ideal for commercial, consumer and industrial applications like measuring the RPM of the wheel, position sensor for machining tools, positional feedback for control systems, detecting the poles of magnets in BLDC Motors, magnetic alarm doors etc. There is a 49E Linear Hall-Effect Sensor, a LM393 Dual Differential Comparator, a potentiometer, two LED's, and six resistors in KY-024 module. With the help of potentiometer, you can change the sensitivity of the module to provide digital output.
- Operating Voltage Range: 2.7V to 6.5V
- Sensitivity 1.0mV per Gmin
- Board Dimension 1.5cm×3.6cm
- Responds to Either Positive or Negative Gauss
- Linear Output for circuit design flexibility
You can read this change in Digital Output to make it work as a switch in your application. You can use digital Read with delay or can use attachinterrupt function in Arduino which read if there is any change in state at the digital pin the attachinterrupt is enabled. In Analog mode you need to connect with any of the onboard Analog pins and then read the value to detect the strength of the magnetic field.
