Description
- This 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 10 bit AD, so this module simulation resolution is 0.00489 V (5 V / 1023), and the input voltage of this module should be more than 0.00489 V x 5 = 0.02445 V.
