Voltage sensor Module

Voltage Sensor Module 25V is 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 a wire.

This module is based on the principle of resistive voltage divider design, it 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).

It has the limit of Arduino analog input 5V DC only. One way is to use a voltage divider. It is fundamentally a 5:1 voltage divider using a 30K and a 7.5K Ohm resistor.

Note: Keep in mind, you are restricted to voltages that are less than 25 volts. More than that and you will exceed the voltage limit of your Arduino input.

Features:

Output Interface: “+ ” connected 5/3.3V, “-” connected GND, “s” connected Arduino AD pins DC input interface: red terminal positive with VCC, negative with GND You can also use the IICLCD1602 LCD to display voltage. By 3P connector, connect this module with the expansion of board Arduino, not only makes it easier for you to detect voltage battery.
