hi
i have china made infrared receiver module .i do not know its manufacture company name. on its back side only type 7y on top and 3C on center and 0012 on bottom . i tryed to find its datasheet but not succes. please tell me how to find its datasheet
I've used some unmarked/salvaged modules in the past. Just used the first pinout I found (Nigel's PIC site), 5 volts, and a 38kHz carrier. Of three I've used so far, none have failed, all from different devices. Pretty sure unless you are doing something precise, should be close enough. They are only a buck or two new, with a datasheet... Not really worth chasing around the web. I used my Osciliscope and the TV remote first time I hooked it up, to see if it was working. 38 kHz is a good target, but give or take a couple of k's will be okay. I used mine for proximity detectors (about 3 feet).
