Description

A simple but very useful module which uses a potential divider to reduce any input voltage by a factor of 5.

This allows you to use the analogue input of a microcontroller to monitor voltages much higher than it capable of sensing.

For example with a 0-5V analogue input range you are able to measure a voltage up to 25V.

The module also includes convenient screw terminals for easy and secure connection of wires.

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 5 v, 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.
