This review is for the "30PCS A3144 Hall Effect Sensor Hall Sensor A3144E A3144EUA OH3144E Magnetic Detector."A simple 10k pullup resistor on the data out pin, and supply voltage to the sensor and this will detect the presence of a magnetic field. Simple and effective.This sensor is not analog, and is not sensitive enough to detect earth's poles. For that, you will need a different sensor.This one just works great as a digital magnetic sensor switch. It's small, takes up little space and is easy to incorporate into any microprocessor application, or even to drive an LED.Good price for 30pc. Worthy of recommendation.
