HEY…HOPE EVERY ONE IS FINE..I WANTED MY ROBOT TO FOLLOW THE HEAVY INFRARED RAYS, EMITTING OBJECTS AND IGNORING LOW INFRARED EMITTING OBJECTS.. CAN I ACCOMPLISH IT USING INFRARED EMITTER/DETECTOR CIRCUITS?? OR ANY OTHER SPECIAL SENSORS WILL BE NEEDED PLZ GUIDE…THANKS..
i don;t want to detect ir radiations of human body ( till 10 microns)and also don;t wana pick up the sunlight that is ranging from (800 to 3200 nm)
hi.. i want to detect Mid-wavelength infrared ranging from 3 micrometere to 8 micrometer that include flame , exhaust etcand ignoring the human bodies / tables / chairs /sunlight ..
hi,, wanted to ask how to plac the convex lens on an ir receiver?? waned to focus its rays to increase the range ?
"Even better... Mount the receiver backwards in a parabolic mirror..."
is it similar to the one as shown in the image below in the link? means in my case the ir receivers will be placed instead of lamps/bulbs....
and if i want to use multiple ir receivers ,each looking in different angle , shall i use a single lens/ mirror for all of them( as the lamps placed in the above image ) or differernt mirror/lens for each sensor?
however i did use an alluminium foil present at base of a pringles cylinder, i cut out a piece of 4.5cm *4.5cm , and placed my sensor at its focus that is 0.222cm using the formula ( y = ax^2 ; y being the folding plane), but did not get any reading (voltage)..
however without the aluminium plate , sensor was giving output. i wanted to ask may be the aluminium foil acts opaque to the radiations or have i used the correct material for parabola reflector??or have i placed the the sensor at the wrong focal length??
