Tutorial on using ratiometric Hall sensors. The module is powered by 5V and has 2 outputs, one is Analog and its DC offset can be set using the trimmer potentiometer, and there’s a Digital output that can be either HIGH or LOW depending on the magnetic field strength and the threshold you’ve set using the trimmer potentiometer. In the hall sensor mode (mode MSEL6x = 1000B), the dead-time counter DTC0 is used (if bit DBYP is 0) as a hardware noise filter to suppress spikes on the Hall inputs. We are going to use a hall effect switch to turn the Arduino UNO's built-in led on and off with a magnet. As the magnet comes closer to the sensor, the output voltage rises. Arduino UNO Tutorial 11 - Hall Effect Switch. A Hall effect sensor is a sensor that responds to a magnetic field. Which is the hall effect sensor it self and the other part is magnet. The hall sensor works on the principle of Hall Effect, which states the whenever a magnetic field is applied in perpendicular direction to the flow of the current, then a potential difference is induced. A hall effect sensor is much smaller, but can handle less current than a reed switch. A ratiometric Hall effect sensor outputs an analog voltage proportional to the magnetic field intensity. Sensors like this can also be used to measure speed (for example, to count how fast a wheel or car engine cam or crankshaft is rotating). The analog hall sensor module contains a hall sensor.
