Description

Module with Hall sensor with analog and digital output. It works with voltage from 2.3 V to 5.3 V. It provides the detection of a magnetic field. The output voltage of the sensor is proportional to the value of the induction of the magnetic field.

The product is compatible with Arduino

The manufacturer has prepared a user guide along witha sample program for Arduino and STM32.

Question: I want to build a circuit that responds to only one pole of the magnet. From what I understand, the AH49E sensor itself can detect which pole we are approaching the magnet with (for S it is the range of 0.5-1.0 supply voltage, and for N it is 0.0-0.5). However, I am not sure how the DOUT pin works. When we apply the S pole, do we get 5 V, and when there is no magnet or we apply the N pole we get 0 V?
Answer: In the absence of field detection, the sensor on the DOUT pin indicates 5 V, and when detected, about 0 V (~0.13 V).

Question: Can this sensor be used with Raspberry pi 4? I read that this model is dedicated to Arduino.
Answer: The module uses an analog signal for communication; unfortunately, the Raspberry Pi does not have a digital-to-analog converter.
