Hi,
I am working on a project that requires IR sensors to detect a line and respond accordingly, I have made the sensor etc, but now want to improve upon it, the one major problem is AMBIENT LIGHT, as the project has to work outside in daylight....
Although the sensor is below the robot and most of the AMBIENT LIGHT is blocked, but I was still wondering if there was any cheap way to block that AMBIENT light and only let the IR pass....
I have searched for it and have found something called COLD MIRROR which does the same thing, I then searched for it and found many OPTICAL COMPANIES selling them, but at very expensive prices.
Here, I have a theory of my own, On all TV sets, I have seen that there is a DARK BROWN PLASTIC, which covers the IR receiver of the TV, I think that it acts as the AMBIENT LIGHT FILTER, does anyone know anything about this.... am I right... I am wrong most of the time, when I think...
Help is required, not URGENT, but it is required....
I have searched for LINE FOLLOWERS and many other stuff the past weeks, but this has not been covered anywhere.....
Thanks for any help I may get here in advance, though I will be checking in QUITE OFTEN on this post....
Regards,
Zaid Pirwani
