Product Details

Description

The Voltage Detection Sensor Module 25V is a simple yet highly effective solution for extending the voltage sensing capabilities of microcontrollers such as Arduino. Using a resistive voltage divider, it safely scales down input voltages up to 25V (16.5V for 3.3V systems) into a measurable range compatible with standard ADC pins. With a resolution of 0.00489V, it ensures precise monitoring for power supplies, batteries, and other electronic circuits. Featuring screw terminal inputs for secure wiring and a convenient 3P connector for Arduino expansion boards, this module is easy to integrate into your projects. It can also be paired with IICLCD1602 LCDs for live voltage display, making it a versatile tool for prototyping and real-world applications. Featured By RoboticsBD.
