Voltage Detection Module Sensor Electronic Bricks

🔌 Voltage Detection Module Sensor | Electronic Bricks for Arduino, ESP32, Raspberry Pi

📦 Product Overview

The Voltage Detection Module Sensor is a compact and efficient tool designed to measure input voltages up to 25V DC using the analog input pins of microcontrollers like Arduino, ESP32, or Raspberry Pi (via ADC). Based on a resistive voltage divider circuit, this module is a must-have for electronics hobbyists, students, and prototyping engineers.

✅ Key Features

• Wide Voltage Detection Range
  Accurately detects DC voltages from 0.024V to 25V (ideal for 5V logic systems).
• High Compatibility
  Compatible with Arduino, ESP32, STM32, and other development boards with analog input.
• Easy to Use
  Clear 3-pin interface: VCC (+), GND (-), and Signal (S) pin connects directly to your analog pin.
• Precise Measurement
  Achieves a resolution of 0.00489V (5V / 1023) × 5 = 0.02445V using 10-bit ADC in Arduino.
• Safe Voltage Scaling
  Internally scales down input voltage by a factor of 5, protecting your controller’s analog inputs.
