Voltage Sensor Module For Arduino DC 0-25V

Very simple module which consists of a 30k and 7.5k Ohm resistor. Essentially a 5:1 voltage divider so you are restricted to a maximum 25V input, anything over will exceed the 5V limit of your arduino.

Inputs:

GND - -ve of measuring input
VCC - +ve of measuring input

Outputs:

S: Arduino analog input.
-: Arduino ground.
+: (Not required)

Specifications:

Input voltage range: DC0-25V
Voltage detection range: DC0.02445V-25V
Voltage analog resolutions: 0.00489V
