25V Voltage Sensor Module

25V Voltage Sensor Module - Main image
$0.3 $0.41 In stock

Category: Sensors

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...

Richard ★★★★★

The voltage divider made it incredibly easy to read my 18V solar panel with an Arduino—no extra components needed. Accuracy seems spot on after testing against my multimeter, which is exactly what I was hoping for.

Ruby C. ★★★★★

Hooked it up to a 12V battery and the 5:1 divider read spot-on through my Arduino's analog pin. Took ten seconds to wire and it's been stable all week.

Julian K. ★★★★★

Finally got around to testing this with my Arduino and the 5:1 voltage division made reading a 12V battery super straightforward. No magic smoke, just clean readings right out of the box — exactly what I needed for a simple battery monitor project.
