operating voltage: 4.5 V-24 V

Series 3144, hall switch integrated circuit with hall effect principle USES the semiconductor integrated technology manufacturing magnetic sensitivity of the circuit, it is through the voltage regulator, hall voltage generator, differential amplifier, schmidt triggers, temperature compensation and the open collector output stage circuit consists of magnetic Sensitive sensor circuit, its input for the magnetic induction intensity, the output is a digital voltage signal.

Hall magnetic sensor module and a digital 13 interface with LED build a simple circuit, produce a magnetic flasher. Use digital 13 interface with the LED, the Hall magnetic sensor connected to the power plate number 3 for ARDUINO interface. When the Hal magnetic sensor has a magnetic field signal, LED lights on, versa lights off.
