Simple DC Voltage Sensor, VDC 25V weather Audio OutputThis DC voltage sensor can detect voltage from 0 to 25V. The sensor is based on the resistance points pressure principle, and it can make the input voltage of the red terminal reduce 5 times of original voltage. The max Arduino analog input voltage is 5 V, so the input voltage of this module should be no more than 5 V x 5 = 25 V ( if for a 3. 3 V system, the input voltage should be no more than 3. 3 V x 5 = 16. 5 V ). Because the Arduino AVR chip has
