Voltage Detection Module Sensor – 0–25V Range for Arduino

Voltage Detection Module Sensor – 0–25V Range for Arduino

Monitor voltage levels with precision using the Voltage Detection Module Sensor, engineered specifically for Arduino and other microcontroller platforms. Based on the resistance voltage division principle, this module safely reduces high input voltages by a factor of five, allowing it to measure up to 25V with a 5V analog input system. It’s a perfect choice for makers, electronics students, and IoT hobbyists.

This electronic brick supports a voltage input range of 0–25V, and delivers a fine-tuned analog resolution of 0.00489V, thanks to the 10-bit ADC in AVR-based Arduino boards. Whether you're building a power monitoring project or need reliable voltage readings for sensor inputs, this module ensures accurate data conversion. It supports both 5V and 3.3V systems, making it versatile across various boards.

Easy to connect and compact in size, the module features clearly labeled VCC, GND, and signal (S) output pins. It comes with one voltage sensor module in the package, ready to plug into your Arduino AD input. Add this to your toolkit for DIY electronics, embedded system design, or automation applications.

Product information:
This module is designed based on the resistance voltage division principle, which can reduce the input voltage of the terminal interface by 5 times, and the voltage of Arduino analog input is 5V, then the input voltage of the voltage detection module cannot be greater than 5V × 5=25V (if 3.3V system is used, the input voltage cannot be greater than 3.3 vx5 = 16.5V). The analog resolution of this module is 0.00489V(5V/1023) because the AVR chip used in Arduino is 10-bit AD, therefore, the voltage detection module detects that the input small voltage is 0.00489V × 5=0.02445V.
