I recently purchased a cheapo set of IR receivers and transmitting diodes. Before using the transmitter diode I want to become more comfortable with the receiving part so I have been messing around with my tv remote using an oscilloscope on my computer to see if I can register an output voltage, and will be attempting to amplify it next. I have had mixed results and can’t find much information on this part in this package and the datasheet is entirely in what appears to be chinese or another asian language.
After learning what I can find about this particular package style if I understand correctly I have learned:
One pin is VCC, another is GND, and a third pin is an output pin.
I pressed buttons on my remote and have registered different voltages, one was actually as high in the 3 Vpp range and others are typically around 50 or 500 mV(I can’t remember and the results don’t seem reliable) but there is undoubtedly a spike at times. I don’t know why the IR sensor seems to stop working shortly after but maybe I am destroying it accidentally since I can’t read the data sheet.
I am using a 5 V supply and all I did was wire a 10k potentiometer with the CW pin tied to the IR output pin and the wiper to ground to use as a variable resistor.
My eventual goal is to make a latching circuit that lights an LED by pushing the remote button.
I am sorry for the wordiness of this post but I can’t seem to find much info on this package and don’t really understand why it would stop working because I am not drawing much current, and I have seen some indication it does work. It is incredibly frustrating and without explaining the exact situation I don’t know if I will be able to figure out what’s going on. Any help would be great, thanks in advance.
