Analog Voltage Divider up to 25V
A simple but very useful module which uses a potential divider to reduce any input voltage by a factor of 5. This allows you to use the analogue input of a microcontroller to monitor voltages much high than it capable of sensing. For example with a 0V - 5V analogue input range, you are able to measure a voltage up to 25V. This module also includes convenient screw terminals for easy and secure connections of a wire.
This module is based on a principle of resistive voltage divider design, & can make the red terminal connector input voltage up to 5 times smaller. Arduino analog input voltages up to 5V, results in the voltage detection module input voltage not being greater than 5V x 5 = 25V (if you're using a 3.3V systems, the input voltage is not greater than 3.3V x 5 = 16.5V).
Note:Arduino AVR chips have 10-Bit AD, so this module simulates a resolution of 0.00489V (5V/1023), so the minimum voltage of input voltage detection module is 0.00489V x 5 = 0.02445V.

Pinout

- Input:
- GND - This is where you connect the low side of the voltage you are measuring. Caution:This is the same electrical point as your Arduino ground.
- VCC - This is where you connect the high side of the voltage your are measuring (0 - 25V)
- Output:
- S: This connects to your Arduino analog input.
- -: This connects to your Arduino ground.
- +: This is not connected. It does absolutely nothing.
