Hi,
Trying to enter IR world I've ordered and received Infrared diode and detector from my regular supplier:
Futurlec, The Electronic Components and Semiconductor Superstore
I tried to get more information about them by typing their numbers INF5940 and INFD5940 but failed to get any other than this. I conclude that the number itself gives the only two piece of information that its 5mm in size and 940nm in range.
Tried to connect them as normal LED ( with clear plastic cap ) practice gave partial success, since the LED when connected with 330 Ohm in series across a 5v supply, gave me a current of 10.83mA and using my camera saw the light bright as in my remote control.
Encouraged by the result I've connected the detector ( with Black plastic cap ) in series with another 330 Ohm across the same 5v supply and measured 11.68 mA current.
Tried to figure wither the detector works or not I've faced both of them together and measured the voltage across the detector. I put a cardboard in between and tried to move it many time to restrict the beam of IR ( if I'm not wrong ) while measuring the voltage across the detector leads which stays 0.87v regardless my cardboard movement.
Is the way I'm testing the detector is correct or not?
Thanks
