Product details

Features:

  • Measurement range: 0–25 V DC
  • Accuracy: ±0.5%

Applications:

  • Measuring battery voltage
  • Measuring solar-panel voltage
  • Measuring power-supply voltage
  • Measuring voltage in other electronic devices

How to use:

Using the module is straightforward. Connect it to an Arduino Uno or another compatible microcontroller. Connect the positive terminal of the voltage source you want to measure to V+ on the module. Connect the negative terminal of the source to the GND terminal. Power the Arduino. Once programmed, the module measures the source voltage and displays readings in the Serial Monitor or on an LCD display.
