Voltage Detection Sensor Module 25V

Product Description

The Voltage Detection Sensor operates on the basic principle of a resistive voltage divider. It consists of a 30KΩ and a 7.5KΩ resistor in series. When a voltage is applied to the input terminals, the output pin provides a reduced voltage that is exactly one-fifth ($1/5$) of the input. This allows a 5V Arduino Analog pin to safely "see" and calculate a 25V input. The module is compact, requires no external power to function, and features high-quality screw terminals for secure wire connections.

Key Features

• Plug-and-Play Compatibility: Works seamlessly with Arduino, AVR, PIC, and Raspberry Pi (with ADC).

• Wide Range: Measures any DC source from near zero up to 25V.

• No External Power Required: The module is passive and draws its reference directly from the source being measured.

• High Precision Resistors: Built with 1% tolerance resistors for reliable data.

• Compact PCB: Small footprint makes it ideal for integrated battery management systems (BMS).

Technical Details

• Input Terminals (VCC/GND): Connect the positive and negative of the DC source you want to measure.

• Output Pins (S/+/–): * S (Signal): Connect to Arduino Analog Pin (e.g., A0).

  • + (NC): Not connected.

  • – (GND): Connect to Arduino GND.
