🔧 Product Overview

The Voltage Sensor Module 5V is an easy-to-use, compact module designed for measuring higher DC voltages safely and accurately with your microcontroller, even when the microcontroller’s analog input range is limited to 5 V.

🚀 Why It’s Great for DIY Projects

• Simple operation: The module uses a precision resistor divider (a 5:1 reduction ratio) to convert input voltages up to roughly 5 times your controller’s analog input limit into a safe range your board can read.

• Ready for prototyping: No complicated calibration or extra components needed — just connect the module to your system and you’re ready to read analog voltages.

• Versatile interfacing: Perfect for use with Arduino, ESP8266/ESP32, Raspberry Pi (via analog-to-digital converter), or any microcontroller with a 0-5 V analog input.

• Compact and low-cost: When size, simplicity and affordability matter, this little board delivers big value.

📝 Typical Use Case

If you’re monitoring the voltage of a lithium battery pack, solar panel, or any DC source whose voltage exceeds what your analog input can handle, just feed the input to this module instead. The module “scales down” the voltage so you can safely read it on your board, all while your system remains protected and accurate.
