Standard Voltage Sensor for Arduino Robot-OKY3509-1

This voltage sensor module is designed for measuring DC voltage with Arduino and other compatible microcontrollers. Based on a resistive voltage divider principle, it safely scales down the input voltage by a factor of five, allowing for direct measurement by a microcontroller's analog pin.

Key Features
- Voltage Range: Measures up to 25V DC with a 5V system or up to 16.5V DC with a 3.3V system.
- Measurement Principle: Utilizes a resistive voltage divider to reduce the input voltage by a 1:5 ratio.
- Resolution: Provides a theoretical resolution of 0.00489V when used with a standard 10-bit ADC (like those on AVR microcontrollers) and a 5V reference.
- Detection Range: The minimum detectable input voltage is 0.02445V.
- Connectivity: Features a simple 3-pin header for easy integration into your projects.

Applications
This module is ideal for projects requiring voltage monitoring. Common uses include checking battery charge levels, monitoring power supply outputs, and building simple DIY voltmeters for various electronic systems.
