I need, the 940nm wavelength, to be detected only by one receiver (with no scattering - ir beam) and the 850nm only by the other one. Is this possible?
I'm thinking of buying an Wrobot Digital 38KHz receiver/transmitter. Does anyone knows it's wavelength?
A 850nm sensor and a 940nm will both respond to either wavelength emitter, it is just that the sensitivity will be less.
What about with a 300nm and 940nm instead?
I got a 38Khz 980nm IR receiver.I want to use an IR transmitter that the receiver will not receive the transmitting IR signal or to receive the IR signal as little as possible.Should I use an 36Khz 940nm emitter or an 38Khz 880nm instead?
Preferable for the minimum efficiency of the my receiver is to use an emitter with different wavelength or different frequency?
Thanks for your reply.Preferable for the minimum efficiency of the my receiver is to use an emitter with different wavelength or different frequency?
