The Voltage Sensor Module (0-25V) uses a precision resistive voltage divider to scale a DC voltage down by a factor of 5, so your Arduino can safely read up to 25V on a single analog pin. It is the easiest way to monitor battery packs and power supplies.
Key Features
- Measures DC voltage from 0V up to 25V
- 5x resistive divider (30kΩ / 7.5kΩ) keeps the pin within safe range
- No external components — screw terminal in, analog out
- Works with Arduino, ESP32, ESP8266 and Raspberry Pi
- Compact board with mounting hole
