Voltage Detection Sensor Module 25V module is based on the principle of resistive voltage divider design, it can make the red terminal connector input voltage 5 times smaller. daroghawala.org Arduino analog input voltages up to 5 v. daroghawala.org The voltage detection module input voltage is not greater than 5Vx5=25V (if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V). daroghawala.org It has a limit of Arduino analog input of 5 VDC only. So if you wish to measure higher voltages, you will need to resort to another means.daroghawala.org One way is to use a voltage divider. daroghawala.org The one discussed here is found all over Amazon and eBay. daroghawala.org It is fundamentally a 5:1 voltage divider using a 30K and a 7.5K Ohm resistor.
