Description:
The Arduino analog input is limited to a 5 VDC input. If you wish to measure higher voltages, you will need to resort to another means. One way is to use a voltage divider. It is fundamentally a 5:1 voltage divider using a 30K and a 7.5K Ohm resistor. Keep in mind, you are restricted to voltages that are less than 25 volts. More than that and you will exceed the voltage limit of your Arduino input.
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: The is where you connect the high side of the voltage you are measuring
Output:
- S: This connects to your Arduino analog input.
- – (or minus): This connects to your Arduino ground.
- +: This is not connected. It does absolutely nothing.
Package Included:
1 X Voltage Detection Sensor Module up to 25V.
