Arduino DC Voltage Sensor Module (0-25V) for DIY

DC 0-25V Voltage Detection Sensor for Arduino & Raspberry Pi Easily and accurately measure DC voltages in your electronics projects with our Voltage Sensor Module. This compact and beginner-friendly module is an essential "electronic building block" for any DIY hobbyist, student, or electronics enthusiast. Based on a simple but reliable 5:1 resistive divider principle, it safely scales down a higher input voltage (from 0V to 25V) into a range that microcontrollers like Arduino, Raspberry Pi, or ESP32 can safely read through their analog pins. It’s the perfect tool for creating projects like a battery level indicator for your 18650 or LiPo battery packs, monitoring a power supply's stability, or building a custom digital voltmeter. Forget complex circuit design; just connect three pins (Signal, VCC, GND) and start measuring! Specifications Input Voltage Range: DC 0V - 25V Voltage Detection Principle: 5:1 Resistive Divider MCU Compatibility: Works with 5V and 3.3V systems Note for 3.3V Systems: Maximum input voltage is 16.5V (3.3V x 5) Output Signal: Analog Voltage Board Size: 28mm x 14mm Pinout: 'S' for Signal (to ADC pin), '+' for VCC (3.3V-5V), '-' for GND
