Voltage Sensor Module

Key Specifications & Features

• Voltage Input Range: 0V to 25V DC (when used with a 5V microcontroller) / 0V to 16.5V DC (with a 3.3V microcontroller).

• Voltage Detection Range: Measures DC voltage up to 5 times the reference voltage input.

• Divider Ratio: 5:1 (Internal resistor network of 30KΩ and 7.5KΩ).

• Analog Resolution: High-precision analog output proportional to the measured DC voltage.

• Interface:

  • Input Side (Terminal Block): VCC (Positive DC supply to measure) and GND (Negative ground reference).

  • Output Side (Header Pins): S (Signal/Analog Out to microcontroller A/D pin), + (Unused/NC), - (Common ground connected to microcontroller GND).

Applications

• Battery voltage monitoring and level detection for IoT or robotics projects.

• Power supply status tracking in automated control systems.

• Solar panel voltage monitoring.
