It is perfect for temperature control (KY-028), the proximity switch (KY-025, KY-036), detecting alarms (KY-037, KY-038) or rotary encoder(KY-026.)
Hall effect magnetic standard linear module for Arduino and other microcontroller projects
- This module uses a hall effect sensor to detect magnetic fields.
- It also has a comparator to give a digital output and an analog output.
- A potentiometer can adjust the level for the digital output.
