Easy to use with Arduino
Module Description:
This module is based on a resistive divider design principles, it will reduce the voltage of the input terminal connection by five times, Arduino analog input voltage up to 5V ony, thefore the input voltage of the voltage detection module cannot be greater than 5V × 5 = 25V ( If 3.3V system used, the input voltage does not exceed 3.3Vx5 = 16.5V). Arduino AVR chips use 10bit AD, so the simulation resolution of this module is 0.00489V (5V / 1023), so the voltage detection module detects minimum input voltage is 0.00489V × 5 = 0.02445V.
Input voltage range: DC0-25V
Voltage detection range: DC0.02445V-25V
Voltage analog resolutions: 0.00489V
DC Input (to measurement): positive terminal connect to VCC, negative terminal to GND
Output interface (to Arduino / AVR board): "+" to 5 / 3.3V, "-" to GND, "s" to Arduino Analog input pin
