Make this IR Remote Control Range Extender Circuit ...

· IR Range Extender Concept. The idea of this circuit is to feed the IR data from an IR transmitter into the transmitter input of an RF module through an IR sensor, and transmit the data in air so that the distant RF receiver module is able to receive the data. After receiving the data the RX would decode it and convert it back to IR based data, which could be used for triggering the relevant IR ...
