In order to check the practical behavior of any electrical or electronic equipment, it is very necessary to install the device which communicate between this electrical or electronic equipment and your real time system. How to Test Hall Effect Sensors by Dan Swords . On a thin strip of a conductor, electrons flow in a straight line when electricity is applied. With the sensor plugged in insert a T-pin in the signal wire cavity of the sensor plug. Pin 2 is the ground, so it receives the ground or negative terminal of the DC power digitalWrite(ledPin, state); However, the reference voltage is usually 5 volts but that varies on some models to 8 volts or to as high as 12 volts (or battery voltage). The working of this circuit is very simple. Well there are a lot of applications which practically use Hall Effect sensor and we might have never noticed them. that it "knows" a magnet is in its vicinity. A Hall effect switch will turn on in the presence of south magnetic field on its face or north magnetic field on the opposite side. pinMode(ledPin, OUTPUT); As per the breakout application note hall effect current sensor connected with target load and output signal is connected with well known Arduino’s A0 (Analog input pin 0).
