3144 Hall switch integrated circuit based on Hall effect principle, the use of manufacturing semiconductor integrated technology of magnetic sensing circuit, it is by voltage adjusting device, Hall voltage generator, differential amplifier, Schmitt trigger, temperature compensation circuit, and an open collector output stage is composed of a magnetic sensing detection circuit. The input for the magnetic induction intensity, the output is a digital voltage signal.

Specifications:

• working voltage: 3.3--5V
• using 3144E switch type Holzer sensor.
• when the sensor sensor to the magnetic field, the digital output low, the signal light is bright; if no induction to the magnetic field, then the digital output high level, the signal light is not bright.
• with power indicator and signal indicator.
• output mode: digital switching output (0 and 1) AO port is not valid
• LM393 comparator output, model clean, good waveform, strong driving ability, more than 15mA.
• Fixed bolt hole is provided, which is convenient for mounting and fixing.
• can be used for motor speed, position detection, etc..
• Sensor function introduction:
