Hi All,
I'm looking to build an IR transmitter and receiver set up for the following requirements:
Needs to transmit and receive to approx 7 - 8 meters in sunlight (adjustable distance would be good)
2 - 3 Receivers to be ground based in tubular housing and receive IR signal from directly above and should provide audible tone with adjustable volume if possible.
IR tx (6-9 volts) will be always on & mounted under a remote controlled helicopter so that when the helicopter is directly over the receiver an audible noise such as a buzzer is heard.
The setup will be mounted in the same fashion as https://rcjapan.net/k-u0026-s-discontin ... only-p-570
Any advise on kits or circuits that could be used would be greatly appreciated.
Matt
