🔋 [DC 0-25V High-Precision Voltage Sensor Module]

This voltage detection module is designed based on the resistive divider principle, which safely scales down an input voltage of up to 25V by a factor of 5. This allows the high voltage to be safely read by the analog input pin of microcontrollers like the Arduino. It is an ideal component for battery level monitoring, power projects, and general electronic experimentation.

✨ Key Features

  • Divider Design: Utilizes a resistive voltage divider circuit to reduce the input voltage by a 5:1 ratio.
  • Wide Voltage Range: Supports a DC voltage input range from 0V to 25V.
  • High Resolution: Analog resolution of 0.00489V (based on a 5V system).
  • MCU Compatible: Works with both 5V and 3.3V microcontroller systems (check maximum input voltage limits accordingly).
