Hi

Does anyone have a source of data sheets and/or instructions for the KEYES modules available through DX or Cutedigi?

Cutedigi and a couple of other sites have some info but most are very light on detail

Thanks

or any of the red sensors (with pots) in this set

Ah, those cheapy ones - I think not, but it wouldn't surprise me if someone's put some useful stuff up about them on a website somewhere - the simplest strategy is to try and read the chip markings from the enlarged photos (like the flame detector one has a 393 comparator and a trimpot and thus is likely a single digital output).  Many of them are very simple so I think you will be able to get many to work without too much headscratching - and the forum hive-mind can help given part numbers etc.
