Voltage Sensor Detection Module (DC 0–25V)

This module is a compact and highly practical tool that utilizes a high-precision resistive voltage divider circuit to step down input voltages by a factor of 5. It allows microcontrollers with a limited analog input range (such as the 0–5V range on an Arduino) to safely and accurately monitor higher DC voltages, such as batteries or power supplies, up to 25V.

Key Features

• 
  

  Voltage Step-Down (5:1 Ratio): Effectively reduces the input voltage by 5 times (e.g., a 25V input becomes a 5V output), making it compatible with standard Analog-to-Digital Converters (ADC).

  
  


• 
  

  Wide Detection Range: Capable of measuring voltages from as low as 0.024V up to 25V DC.

  
  


• 
  

  Secure Connectivity: Equipped with durable screw terminals for the input voltage and a standard 3-pin header for the microcontroller interface.

  
  


• 
  

  High Resolution: When used with a 10-bit ADC (like Arduino's), it provides a sensing resolution of approximately 0.00489V per step.

  
  


• 
  

  Safety First: Protects sensitive microcontroller pins from high-voltage damage by ensuring the signal stays within safe logic levels.
