Hall effect magnetic field sensor will detect the presence of nearby magnets.

Its electric signal is amplified by an IC which can provides a digital and an analog

output for further processing.

Board connections:

Vcc: 3.3V to 5V  

GND: Negative terminal of battery
DO： Digital output, max. current 16ma. ( goes low when magnetic field is detected) 

AO： Analog output (varies with the intensity of magnetic field) 

Dimensions:  32 x 14mm

Mounting holes:  3mm

Power indicator:  LED
