“Took me a while to figure out how to use this since no instructions were provided and the PCB is not labelled. All resources I found online were not for a model like this one. The previous reviewer helped me. Pi Hut, create a simple data sheet with a diagram of the wiring and state which potentiometer with for timeout and which is for sensitivity. Or put in your website with a link from the product page. Seems to work in tests now but only three stars since there was no information provided.”
