Hello,
I'm trying to detect if an IR Led is on and if it is how intense is the light.
For this purpose I tried to use a PNA4601M IR Receiver (http://parallax.com/product/350-00014) that I bought from Parallax a while ago.
I thought the I could simply connect the Vcc of the IR Receiver to 5v, the GND and read the voltage out through the Vout. The higher the voltage, the stronger the IR Light shinning on the IR Receiver. But that is not what happened.
After applying 5V to the Vcc, connecting the GND and reading the output (Vout), I get 5V (a bit lower than the input), even with the IR Led turned off.
What am I missing here? Any clues?
Thanks a lot,
