KY-003 Hall Magnetic Sensor Module For Arduino AVR Smart Cars DIY Starter Kits for Arduino
Features:
Hall-Effect Sensor: Utilizes the A3144 Hall-effect switch, which is highly sensitive to magnetic fields.
Integrated Circuit: The sensor includes a reverse polarity protection diode, a square Hall voltage generator, a temperature compensation circuit, a small signal amplifier, a Schmitt trigger, and an open collector output.
Operating Voltage: Works at 5V, making it compatible with most microcontrollers1.
Digital Output: Provides a digital signal output that can be easily read by microcontrollers like Arduino.
Simple Connection: The module has three pins: GND (ground), VCC (power supply, 5V), and Signal (digital output).
These features make the KY-003 module ideal for applications requiring the detection and measurement of magnetic fields with high reliability and precision.
