VOLTAGE SENSOR MODULE 25V

The Voltage Sensor Module 25V is an electronic device designed to measure DC voltage levels up to 25 volts. It operates as a precision voltage divider, scaling higher input voltages down to a safe level that can be accurately read by microcontrollers. The module provides an analog output voltage proportional to the input, enabling precise voltage monitoring through an ADC (Analog-to-Digital Converter). It is widely used in power monitoring, battery management systems, solar energy applications, embedded electronics, and educational projects.

WORKING PRINCIPLE

The module utilizes a precision resistor voltage divider network to reduce the input voltage from 0–25V DC to a lower level, typically 0–5V, suitable for microcontroller analog inputs. The microcontroller reads this scaled voltage and calculates the actual input voltage using a predefined scaling factor. This allows safe, accurate, and real-time voltage monitoring in a variety of applications, from batteries to power supplies and solar panels.

TECHNICAL SPECIFICATIONS

The Voltage Sensor Module 25V measures DC voltage from 0 to 25 volts and is compatible with 3.3 V and 5 V logic systems. It outputs an analog voltage and typically uses a scaling ratio of 5:1. The module features VCC, GND, and Analog Output pins for easy integration with microcontrollers. Measurement accuracy depends on the ADC resolution and proper calibration. It is compatible with Arduino, ESP32, ESP8266, Raspberry Pi (with ADC), and PLC systems, making it versatile for embedded and IoT applications.

APPLICATIONS

This module is ideal for DC voltage monitoring, battery voltage measurement, solar panel monitoring, power supply testing, embedded and IoT projects, as well as educational and laboratory use. Its compact design, reliable performance, and ease of integration make it a valuable tool for both practical and experimental electronics projects.
