This module is based on principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller. Arduino analog input voltages up to 5V, the voltage detection module input voltage not greater than 5Vx5=25V (if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V).
Arduino AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023), so the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V
DESCRIPTIONS Based on the precise, low-offset, linear Hall circuit, this module provides economical and precise solutions for AC or DC current sensing in industrial, commercial, and communications systems.
With this module your DIY car or robot can walk only along one line way. When the detector move from white to black, it could output TTL signal, So if you draw one black line between in the two wheels of your car, it will walk along your expecting road.
