Description
This reed sensor module is a magnetic switch designed for detecting the presence of a magnetic field.
Normally open by default, the sensor closes the circuit when exposed to a magnetic field triggering a digital output signal.
Equipped with an LM393 comparator and an adjustable onboard potentiometer, this module allows you to fine tune the sensitivity to suit a variety of applications.
Perfect for Arduino, AVR, and Raspberry Pi projects where magnetic proximity detection is needed.
