Frequently Asked Questions
Q: Is this Hall sensor module compatible with both 3.3V and 5V microcontrollers?
A: The Hall sensor module operates at a working voltage of 3.3V, making it directly compatible with STM32 and Raspberry Pi boards. For 5V Arduino boards, a logic level shifter or voltage divider is recommended to ensure safe operation and reliable signal integrity.
Q: What programming routines are included with this Hall sensor?
A: This Hall sensor module comes with ready-to-use code routines for three popular platforms: STM32, Arduino, and Raspberry Pi. These routines allow you to read the digital magnetic sensor output and measure rotating object positions with minimal setup time.
Q: What type of magnet is needed to use this sensor module?
A: The 49E Linear Hall sensor responds to changes in a magnetic field. A standard neodymium or ferrite magnet attached to a rotating shaft or moving object is sufficient to trigger accurate position readings. Magnet size and placement will affect sensitivity and range.
