This is a basic��Voltage Sensor module��to measure the voltage across two terminals. The module operates in 5V and can measure voltage from 0V to 25V using a potential divider circuit. A pair of��high precession resistors��form a��voltage divider circuit��which converts the input 0-25V to 0-5V on the output pin of the sensor. This 0-5V can then be measured by a microcontroller like Arduino.
Do not supply more than 25V to this module as the output voltage will exceed 5V and damage the microcontrol"131" width="334" alt="" src="https://cdn.shopify.com/s/files/1/0300/6424/6919/files/Voltage-Sensor-Module-Pinout_480x480.png?v=1588180935">
Arduino AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023), so the minimum voltage of the input voltage detection module is 0.00489Vx5=0.02445V.
