Keyestudio Voltage Detection Μodule can achieve to detect the voltage greater than 5V. It is designed on the basis of resistive voltage divider principle, which can make the input voltage of bindingpost interface narrow 5 times, and the analog input voltage is up to 5V, thus the input voltage of voltage detection module is not greater than 5V * 5 = 25V (if using 3.3V system, the input voltage is not greater than 3.3V*5 = 16.5V).
Specification
- Working voltage:0V-25V DC
- Signal type: analog signal
