The Voltage Sensor Module DC 0-25V is used to measure the voltage levels of DC circuits within a range of 0 to 25 volts. It is often used in microcontroller projects to monitor battery levels, power supplies, or other DC voltages. Below are the detailed specifications and features:
Specifications
Input Voltage Range: 0V to 25V DC
Output Voltage Range: 0V to 5V DC (proportional to the input voltage)
Voltage Measurement Accuracy: ±1% (dependent on the ADC accuracy of the microcontroller)
Conversion Ratio: The module uses a voltage divider circuit, typically with a ratio of 5:1. This means the input voltage is divided by 5, making a 25V input correspond to a 5V output.
Interface: Analog output
Dimensions: Typically around 30mm x 12mm x 10mm (may vary by manufacturer)
Weight: Lightweight, generally a few grams
Pin Configuration
VCC: Positive voltage input (0-25V)
GND: Ground
OUT: Analog output voltage (0-5V, proportional to the input voltage)
Features
Wide Voltage Range: Can measure DC voltages from 0V to 25V.
Analog Output: Provides an analog output that can be read by an analog-to-digital converter (ADC) on a microcontroller.
Easy Integration: A simple 3-pin interface makes it easy to integrate with various microcontroller platforms such as Arduino, Raspberry Pi, etc.
Voltage Divider Circuit: A built-in voltage divider reduces the input voltage to a safe level for the ADC.
Compact Size: Small and lightweight, easy to fit into various project enclosures.
