The A3144 Hall Effect Sensor Magnet Detector Switch for Arduino is a switch that will turn on/off in a magnetic field. If no magnetic field is present, the signal line of the sensor is HIGH (3.5 V). If a magnetic field is presented to the sensor, the signal line goes LOW, at the same time the LED on the sensor lights up. An onboard LED will also indicate the presence of a magnetic field. The A3144 Hall Effect Sensor Module is a versatile electronic component widely used in various applications. Utilizing the Hall Effect principle, this sensor can detect the presence of magnetic fields. Its compact design and compatibility with different microcontrollers make it suitable for integration into projects such as magnetic switches, proximity sensing, and motor control systems.
