A3144 Hall Effect Sensor Module

The A3144 Hall Effect Sensor Magnet Detector Switch for Arduino functions as a switch that activates or deactivates in the presence of a magnetic field. When there is no magnetic field, the sensor's signal line remains HIGH (3.5 V). However, when a magnetic field is detected, the signal line drops to LOW, and the onboard LED lights up to indicate this change. Additionally, another LED on the sensor also shows the presence of the magnetic field.

Pin Connection:-

Connect the Powerline (middle) to +5V and ground (-) to GND. Connectsignal (s) to any digital pin on the Arduino.
