The DC Voltage Sensor Module is a simple yet powerful tool for measuring DC voltages in electronic projects. It uses a resistive voltage divider to reduce the input voltage to a safe level for microcontroller ADC (Analog-to-Digital Converter) pins, making it ideal for monitoring battery levels, solar panel outputs, or other DC circuits.

It’s compatible with Arduino, ESP8266, ESP32, Raspberry Pi (via ADC), and other development boards. Simply connect the module’s output to your controller’s analog input, and you can read real-time voltage values in your program.
