Product Description

       The Linear Magnetic Hall sensor module and a digital interface, built-in 13 LED build a simple circuit to produce a magnetic field warning lamp comes with digital interfaces of the LED, the linear Hall sensor magnetometer access number 3 interface, when linear Hall magnetometer Sensor senses a key signal, LED lights, otherwise off.

         Hall switch integrated circuit using hall effect principle, Uses the semiconductor integrated technology manufacturing magnetic susceptibility of the circuit, it is by the voltage regulator, hall voltage generator, differential amplifier, Schmitt triggers, temperature compensation, and the open collector output stage circuit composed of magnetic sensitive sensor circuit, its input for the magnetic induction intensity, the output is a digital voltage signal.
