Infra Red Link - A basic Infra Red Link for audio communication for distances upto 3 metres. __ Designed by Milan Markovic Infra Red Remote Control Extender - This circuit is used to relay signals from an Infra Red remote control in one room to an IR controlled appliance in another room. __ Designed by Andy Collison
Infra Red Remote Transponder - Remote-transponder, which lets send signals from a small receiver into closed (opaque door) cabinets, and around corners, etc. Anyways, the main problem is just stray environmental noise with any slowly changing amplitude modulated IR signal (lots of 60 Hz noise, and sunlight noise) . Most IR remotes work around a 40KHz carrier, so that they can just pulse this digitally, and just bandpass filter it at the receiving end. This boosts the range of unfocused IR remotes to tens of feet (around 20-30 feet) . Adding two IR LEDs helps a lot, by sending out more IR signals. __ Designed by Shishin Yamada

Infra Red Switch - This is a single channel (on / off) universal switch that may be used with any Infra Red remote control using 36-38kHz. (This is a very common remote handset frequency) . In place of IR1 a TSOP1738 receiver may be used. __ Designed by Radio LocMan

Infra Red TV Extender - After building both my Mark 1 and Mark 2 circuits, Mr Bocquillon has made an improved version, which is working very well. His design is based is based on an active filter, centered at 37KHz modulating frequency and uses a photodiode and op-amp from Texas Instruments __ Designed by Guy Bocquillon 21-3-07
Infra Remote Control Tester - A simple IR receiver to facilitate in testing of Infra Red Remote Control handsets. __ Designed by Andy Collison
Infrared Alarm Barrier - This infrared alarm barrier can be used to detect persons passing through doorways, corridors and small gates. The transmitter emits a beam of infrared light which is invisible to the human eye. The buzzer at the output of the receiver is activated when the light beam is interrupted by a person passing through it. Infrared __ Designed by Popescu Marian

Infrared Beam Break Detector - Application An infrared detector that sounds a buzzer when an IR beam is broken, meaning the IR signal is lost. A pulsed IR signal generator is necessary, but not included in this post. This project would be ideal for doorways or hallways to alert when someone enters or exits an area.
