*********************************************
I have an opto-electrical circuit design using an optical transistor OP506A,
and an Operational Amplifier TL072. When the Optical-eye is covered (no
light goes to the optical eye), positive input (Pin 3) of the TL072 goes to
+5V, then the output of the TL072 is triggered.
The Problem:
when the Optical eye is covered or darkened continuously (For
Example: If the device left "ON" in a dark room at night), the output trigger is repeated continuously. How could I prevent the continuous trigger of the output? Could I change my Optical device to a one that trigger once? Any body has any idea?
*************************************************
I thank jbartos so much for his or her help on TL072 and the web Sites addresses.
Does anybody know any round regular LED shape and size that can replace EESB5 optical transistor. Can any body give me a hint where I can find a good optical circuit using EESB5 or OP505 Optical transistors.
I thanks all the people in advance.
