Analog Hall-effect Description


Returns an analog signal based on the intensity of a magnetic field. Module outputs the analog sensor signal, as well as (for some modules) a digital signal that is switched high when the sensor level crosses a preset threshold. The threshold is set via the potentiometer.

Also called: linear hall, magnetic hall, KY035, KY024.

Found in kits: 20 sensors, 37 sensors, 45 sensors (analog only, small board).

Found in kits: 37 sensors, 45 sensors (analog and threshold/digital, longer board).


Analog Hall-effect Specification/Notes:


• Voltage: 3.3V to 5.0V
• LED: Power (longer board)
• LED: Threshold (longer board)
• Size: 15mm X 20mm, 15mm X 35mm
• Main component: SS49E/CYL49E linear hall CYL49E

Sensor board has a potentiometer for sensitivity adjustment. Can be used for current sensing with appropriate circuitry. Use with a magnet for positioning.

There are a number of different sources for these modules. Not every module that looks similar to the ones here behaves exactly the same. Check the specific module that you have for differences in function, voltage levels, pinout, and inactive/active states. Some modules have been found to have incorrectly labeled pins and even poorly soldered components.
