Specifications

Key Features

• Wide Measurement Range: Reads DC voltages from 0V to 25V with high accuracy using a precision resistor divider network.
• Microcontroller-Safe Output: Scales down input voltage to a 0-5V analog signal, safe for 5V ADC pins on Arduino and similar boards.
• Simple 3-Pin Interface: Connect directly to any analog input - Signal (S), VCC (+), and GND (-) for instant voltage readings.
• Screw Terminal Input: Secure screw terminal block for easy and reliable connection to the voltage source being measured.
• Ultra-Low Power Draw: High-impedance resistor divider draws negligible current, ensuring minimal impact on the circuit under test.
• Compact & Lightweight: Tiny form factor fits easily on breadboards, inside enclosures, or mounted on project PCBs.
• Universal Compatibility: Works seamlessly with Arduino Uno, Mega, Nano, ESP32, ESP8266, STM32, Raspberry Pi (with external ADC), and more.
• No External Components Needed: Ready to use out of the box - simply wire, upload a short sketch, and start measuring.

How It Works

The Voltage Sensor Module 25V uses a simple resistive voltage divider consisting of a 30kOhm and a 7.5kOhm resistor in series. When a DC voltage (up to 25V) is applied across the screw terminal input, the divider scales it down by a factor of 5, producing an output between 0V and 5V. This scaled output is fed to the analog pin of your microcontroller, which reads it via its built-in ADC. By multiplying the ADC reading by the divider ratio in your code, you can accurately reconstruct the original input voltage.
