Hello, I am working with TSOP38238 (the data sheet is http://www.vishay.com/docs/81733/tsop382.pdf )
The problem I am getting is that it puts out pulses about every 2-3 seconds which throws off my microcontroller.
I have built the circuit as defined in the data sheet using a 220 ohm resistor and a 0.1uF cap.
It does read the infrared remote well enough, but its the other pulses that I have the issue with.
I watched it on my oscilliscope and every 2-3 seconds a bunch of pulses go thorugh. I have 30 of these sensors, and I have tried it on others with the same response. Is this something inherent with this sensor, or am I doing something wrong?
Thanks.
Jeff
