his is a simple but very useful module which uses a potential divider to reduce an input voltage by a factor of 5. The Voltage Detection Sensor Module 25V allows you to use the analog input of a microcontroller to monitor voltages much higher than it capable of sensing.
For example with a 0-5V analog 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 a wire.
This module is based on the 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).
