Description

The Voltage Sensor Module is a compact and reliable electronic component designed to measure and monitor DC voltage accurately. Built for seamless compatibility with Arduino and other microcontrollers, this module allows users to safely detect voltage levels by stepping them down using a precision voltage divider. It is an essential tool for Arduino users, students, engineers, and DIY enthusiasts working on embedded systems and automation projects.

This module can measure voltages up to 25V DC, ensuring safe and accurate readings without damaging sensitive analog input pins. It is widely used in battery monitoring, solar energy systems, robotics, and power supply testing. Its compact size, ease of use, and dependable performance make it suitable for both beginners and professionals.

Connecting the module with Arduino is simple. Connect the VCC pin to the positive terminal of the voltage source, GND to the ground, and the Signal (S) pin to an analog input such as A0. With basic programming, Arduino converts the analog signal into real-time voltage readings, making it ideal for educational and practical applications.

Students frequently use this module in minor and major academic projects such as digital voltmeters, smart energy meters, and battery health monitoring systems.
