Voltage Sensor
This module is based on a resilient divider principle design,
interface terminal input voltage is reduced by a factor of 5. It has a maximum input value of 25v.
So the maximum output value you can get by giving 25v is 5v.
Input voltage: DC0 ~ 25V
Test range: DC0.02445V ~ 25V
Analog resolution: 0.00489V
Inputs
GND - Minus lead
VCC : Positive lead
Outputs
Q: Connects to your Arduino analog input.
- : connected to Arduino ground.
+: not connected.
