DC 0-25V Voltage Sensor tester Module Test Electronic Bricks

Product description:

This modular design is based on the resistive divider principle, which reduces the interface terminal input voltage by 5 times, Arduin support analog input voltage up to 5V, so the input voltage of the voltage detection module can not be greater than 5V × 5 = 25V (if used 3.3V system, the input voltage can not exceed 3.3V x 5 = 16.5V). Arduino AVR chips use 10 AD, so the resolution of the analog module is 0.00489V (5V / 1023), and hence voltage detection module detects a minimum input voltage of 0.00489V × 5 = 0.02445V.
