Hi, i wanna use TSOP as a reciever for a white line follower , i know it needs 38Khz or so to operatate but i dont know where to change to adjust for white calibration ??

thanks

Ahmed

but i dont know where to change to adjust for white calibration ??


why u need to calibrate tsop????
if its tsop1738... it ll receive 38khz i r...
the output ll become logic 0 wen it receives ir..
tats it.. simple to use..

It wont work with White...so no calibration!

I dont think a TSOP will work for line following, its far too sensitive. Even if it does isnt a TSOP a bit of an overkill for following a line?

Yup!
Had to hide the TSOPs inside 20 bucks worth of MSEAL, with a pinhole aperture. to make it usable for LFR.

Funny: my first LFR was made using a top opened BC109C as a light detector...ideal sensitivity for LFRs!!!

ya..
its very sensitive..
so shielding ll be a problem..
better go for normal tx and rx pair...
tats d best for line folower

Yes I agree with everyone out there , why to overprice yourself and overstrain yourself too by using TSOP when your work can be done using just a pair of led n diode.

Hai Ahmed...

Use a phototransistor ir led pair, and use a comparator to interface with the micro. Its working fine for me.

TSOP is a bit troublesome, u need good alignment.
use a bright led -LDR pair instead it works fine.[/b]

TSOP ?? , why u gettin in all that fuss ,,, just get the normal IR led and sensor , just hide the Led and sensor in a small cylinder , too protect it from other light sources ..

Use Opto reflective sensors. which have led and photo transistor in single package. U can try for RPR 220 which should cost around Rs.70.

Yes, I do agree with you. I've an IR pair but don't have it's datasheet. Both looks same but one has longer leads. How to distinguish them for TX and RX? Is there any application circuit for this?
