Dear Fred Kirungi, Thank you for the inquiry. The SIG-5441 supports dry contact, wet contact, NPN, and PNP input types, with a 4.5V–25V range. Based on your description, it seems to be compatible with your water sensor. You can wire it as follows: red to the V pin, black to the G pin, and white to one of the SIG-5441's input pins. For more details, please refer to the SIG-5441 User Manual: https://www.eztcp.com/en/download/pds_files/sig5441en.pdf Please feel free to contact us if you have any questions. Thank you very much.

I have a water sensor which puts out a digital on-off signal. Connection instructions say "The red wire of the sensor is connected to 5V,the black wire is connected to GND,and the white wire is connected to the MCU IO port." Is this the right product?
