Finding the wiring Schema was a pain. 1 White goes to 5V 2 blue connect via resistor (220R) to 5V 3 yellow is Signal (Pull down via 4k7 resistor) 4 red is GND It would be much more according to standard if Red would be 5V white 5V via resistor blue GND and Yellow Signal ... especially having red as ground is strange ...

low cost product but I need to ask again and again about wiring/connection to customer service. Why not all info available on product info page?
