1st Image represent contious signal from PIC Driven IR @ 38.3KHZ (output from TSOP1838 out pin)
2nd Image Represent when Signal is break (beam break Detector) (output from TSOP1838 out pin)
I need help, how to use Change on Interrupt function of PIC to detect if the beam is broken or not ? signal is having 8.7hz frequency so every 0.114 Seconds it changes so its just like led blinking... how to detect the straight line and stay normal while 8.7hz signal is received ?
i am trying to make Beam break detector. But i am not able to differentiate the signal output from TSOP1838.
Please help.
