#91353 - IR will work: Responding to: ???'s previous message |
Dear Mahmood,
The IR uses a modulated beam, (the same as domestic remote controls) the demodulator is tuned to that frequency. It will work even in the Sun or the Daylight. All you need to put the sensor (demodultor) in a small tube like thing to protect from as much light as you can or from the direct sunlight. The reflected IR beam from the sunny obstacle would however, still work without any problem, as you only need reflections. Regards Babar |
