Hai all,
am using an IR sensor with six tx and rx to detect objects fallinf from top. in that center part has blind spot. its not detecting object. help me to clear the error.
Hi,
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png.
Can you please post a copy of your sketch, using code tags?
They are made with the </> icon in the reply Menu.
See section 7 http://forum.arduino.cc/index.php/topic,148850.0.html
What is your application, we cannot help you without information about you project.
Thanks.... Tom.... 
Have you been staring at the laser again?
The blind spot is yours.
You have failed to explain your setup. Have another try.
am using only infrared. am keeping 6 sensor in same board but Rx and Tx in seperately. if pass any object in between 3&4 sensor its not getting detected.
Hi,
See post #1.

What infrared? Manufacturer/Model/Specification/How is it connected Arduino?
What Model Arduino?
You have 24 postings in this forum?

What is you country? Your language?
Have you tried removing sensor 3&4 and replacing them with sensors like 1&2 or 5&6 ?
You probably can't do much with my answer. But keep in mind you, more or less, keep asking for a new tire, without mentioning what type of vehicle you drive.
Tons of infrared sensors, for loads of different applications, are available for example.
If you don't tell which one and don't describe your setup better, it's hard to give you better answers as above.
Problem might... be as simple as a loose connection, your sensors might not be the best for the job, 3&4 could simply be broken, perhaps you've misread a datasheet, but it could also be a programming error, as well. Without detailed info, it unfortunately is hard to tell/help.

Crystal Ball is on the table.
1). If you have IR sensors that use TX and RX, if you have all of them turned on together, what is to stop TX of adjacent sensor reflecting back into Rx.
OR
2). If you are switching each IR pair on and off, so only one active at a time, how have you got them physically arranged.
I suspect you have the first option because of the continuous realtime readings needed, and that you problem is crosstalk beteen IR units.
PLEASE READ POST #2 #3 #4 and #5.
Thanks, we want to help but without information we cannot give accurate info.
