QUOTE(sooyewguan @ Sep 11 2007, 10:22 PM) whats ur application ? r u sure u got the right pair of transmitter and receiver as there are different of wavelength for IR yaya...tats confusing me actually..cos most of the shop don provide datasheet for the IR transmitter and receiver..can u shwo some list??basically im building a robot to avoid obstacles..then if the IR signal detected any object in front,it will reflect back to my receiver... i need a proper datasheet of the transmitter and receiver as i don kno much bout it...and those shop selling in jalan pasar don provide them  |

Just google for it or register to www.farnell.com or www.rscomponents.com, and try searching in their database for datasheets. Alright..thxs for the info,ill try to search the correct sensor for my project |
