Detect Hama IR Remote Protocol

I'm working on an universal receiver and I'm not able to detect what protocol is used by the Hama VRC-1100 MCE Remote. The signal is this: The Time/Div is set to 2 mS and the distance between a sequence and another is about 49 mS. Because of the…

Universal IR Receiver for TV Remotes

I'm trying to build a device that is able learn a command from a TV IR Remote and recognise when this command is sent to it. I've see that the most common protocols used are NEC and Philips and that the frequency may vary of some kHz depending on…

What part is used in this IR receiver?

I bought an IR repeater with the simple schematic: What is this receiver component? It looks almost like TSOP4838, has the same pinout, but it outputs an encoded signal and I cannot find what is it. TSOP4838 (right) and this one (left) Back…

tsop348 infrared receiver

Why do they tell that • Burst length should be 10 cycles/burst or longer. After each burst which is between 10 cycles and 70 cycles a gap time of at least 14 cycles is necessary whereas I see only 7 in the 600us bursts of their time diagram…

IR receiver output pulsating instead of constant one('5V') or zero ('0V')

I am trying to detect the size of different bottles on a conveyor belt and for that I thought of using IR transmitter and receiver but I am not getting desired output. I want the output of IR receiver to be constant '1' or '0' but instead I am…

IR receiver part interchange

I've got an old stereo that doesn't have a remote control. There was a model that did, and after looking at the service manual it looks like I just need to populate a PCB with an IR receiver to add that functionality. However the part isn't…

Unexpected behavior when using 5V from one power supply and Ground from another one

I am trying to use an old phone charger with 5V DC output. I measured the output to be 6.4V. It works for powering an ESP8266 through VIN but does not work to power an IR receiver I want to use. The receiver works when I power it through a…
