IR Receiver Circuit Diagram (Infrared)

The Infrared Receiver is designed to work together with the infra-red transmitter mentioned in the previous post, to create a complete infra-red remote control system. Instead of coding and decoding, the transmitter’s carrier is altered in a simple way to produce consistent switching signals. The receiver module is set to switch from low to high when the carrier signal is received for over 200 milliseconds.
IR Transmitter Circuit Diagram (Infrared)

The Infrared IR Transmitter is intended primarily for the testing of infrared receivers. The test is possible in most cases even without having the associated remote control available. Of course, the test will then be limited to just the infra-red sensor device in the receiver, but it is very useful to begin with when it comes to faultfinding in an infra-red controlled system like a TV set or a VCR.
