AJMRTC KY-003 Hall Magnetic Sensor Module adopts A3144 Hall effect switch chip to detect nearby magnetic fields and convert magnetic signals into digital output signals. It comes with a built-in indicator LED that illuminates once the sensor picks up magnetic force, helping users confirm working status intuitively. With 3 simple pins for power, ground and signal output, this module can be directly connected to Arduino, AVR, Raspberry Pi and other mainstream microcontrollers without extra conversion circuits. Featuring non-contact triggering, stable performance and low power draw, it is widely used for motor speed counting, magnet position detection, automatic switches, car modification projects and electronic learning experiments. This sensor is a must-have component for maker DIY projects, university lab teaching and embedded system development.
