Description

Voltage Detection Sensor Module 25V

This 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. This voltage sensor 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).

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.

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.

Useful little boards

These little modules work just fine for measuring voltage. Although anyone could easily make their own, these are so cheap, why bother making your own

Very happy

Each and every one of the lot works perfectly.

Divide by 5 Voltage divider modules.

These are actually Divide By 5 Voltage Dividers consisting of 30K and 7.5K resistors. Accuracy is fair, about 1% and good enough for most applications. I am using them to scale down 50 watt solar panel voltages to within the 0-5 volt range of the Arduino Pro Mini's A/D inputs and they work good. Connections to the modules are a little strange but not a problem. For future projects though I will use individual 0.1% 30k and 7.5k resistors which I found recently at very good prices.

Raspberry pi voltage reading

Works good. Slight varience in readings. Using with mcp3008 for reading voltage on raspberry pi. If you use this with raspberry pi make sure to use 3.3v to not burn out your gpio. And to stabalize readings pull multiple times and average reading. Adafruit mcp3008 tutorial works perfect.
