What did you find with a lrl

[Morgan]

tell about the test you made, and what kind of IR LED used

[Morgan]

you can invert LED polarity , check for results

I have my own circuit and it works very well, except that I didn't succeed yours ,

hare's my IR LRL , i use two different wavelength leds for reception , and UV transmitter ,

Abdou LRL IR/UV

I have my own circuit and it works very well, except that I didn't succeed yours ,

hare's my IR LRL , i use two different wavelength leds for reception , and UV transmitter ,

that looks very professional,
remember this circuit has very little range and work pointed to ground ,not horizontal has the other IR/UV,
this circuit using IR LED can locate a gold medal buried 20cm deep ,more than 20 years ago,at only 1,20m above the medal...
Its a simple project,for beginers.

[Morgan]

for accurate results you need to have a field test with GOLD to check the IR sensor how it works,
just to play with this project in the back yard garden will be deceiving if gold is not present.

[abdou2014]

yes it's a shame that I don't have a gold test field , but I have a target detected with PDK 3.

what is the difference between this simple 1.2 meter circuit, and the LRL IR/UV circuit ?

[humhum]

I want to know , does Yours IR receivers works also in Night time or works in all wheater coundition (Sun - Dark) ???

Regards. )

[abdou2014]

I don't know to whom this question is addressed ?

my IR LRL which is in the picture works in all conditions, day and night, it detects the

variations in the infrared beam of the transmitter , and the previous photo only works in a

sunny day

[humhum]

Hi Abdou ,What is different in works prencibe of Your two variation ?
May be one is only with IR receiver Led (not use UV Tx led) and need Sun ,
Other type use IR receiver Led and UV tx led , for this not need Sun , or does You use
IR Tx led + IR receiver Led prencibe , also when you use two IR Led for Receiver ,
then one is for Gold nm and other for Silver nm .

I think in videos you can see the great diference are distances, and this AT122 locate my gold target medal and no good results in silver target, maybe if try other IR rx things can be diferent, this is a beginers project.

Thank you Mr Morgan

[humhum]

all entusiasts can play with this short range IR receiver, you can use rx LED IR 740 to 940nm ,need to instal the LED in a dark tube to work, very good for beginners experiments with Infra Red locators,very simple and easy to get TIP122

Yes Morgan , this Sch works with Simulation , but when You use 4,7 uF or 10uF instead 47uF circuit will be more Fast !!

[Morgan]

ok, thanks

Hi Morgan
Nice IR LRL for pinpointing!

Complete your schematic.

E-mail me to tell you how to rise the distance. If you want real full IR LRL invest in parts for both. We could make tests at your field in portugal and then at Pyrenees mountain.
IR Optics make miracles.

I make test with my Silver buried , but witout Result , may be need Gold buried medal
