Distance between sender diodes and admissive transistors may be up to 30mm, and beside the good optics and reducing resistor IC diodes SFH409 with 180 on 100R, possible is the distance and next to 70mm. For the extra enlargement of reach was able will use the additional amplifier AC of signal (npr with the reinforcement 10,). Reason this is what is necessary relative large minimal amplitudes of signals (50mVpp) on the entrance in LM567, and who is a far cry from above the level of noise. On the lower scheme has been the example with additional AC amplifier. The maximal distance between radio transmitters and receivers has been enlarged up to 25cm (without the special optics). Requires will take care of that is AC amplifier around IC of detector because of decreases of disturbances.</div> <bR> <div> <IMG SRC="54758030.gif" border=0 width="600" height="259" ALT="IC fotoćelija" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>  <ins class="adsbygoogle" style="display:inline-block;width:728px;height:90px" data-ad-client="ca-pub-2650537455752702" data-ad-slot="5163197671"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({}); </script> <bR> <div>      Same, instead of infrared diodes was able will use and high efficient narrow angle red LED of diodes (1000mcd). Substantially is the low cost from IC diodes, and function more effectively and was able immediately to see itself that is active. Complex has test and work good on daily light (on the sunned place). Receiver maintains and direct illumination lightings without the interference in the work. Response of detector is fast these it likely recognizing interrupts and establish optic visibilities in the time shorter from 500us (necessary adjusts exit RC filter in order to the such signal passed distances).</div> <bR> <div>      If the exit has been intended for the alone signalization, then the twinkling in the marginal area and is not so much importantly. However, if want the reliable signal, then recommend the usage of filter and schmitt the flip-flop of complex (e.g. 74HC14) outbound LM567.</div> <bR> <div>      Options of use of separated radio transmitters and receivers uses in integrated in the same housing. For example, was able will use the reflex sensor CNY70. He may be illuminated and on unmodulated IC to the bundle was easily can false will appear the exit. Use this complex never happens that the sensor false reacts.</div> <bR> </td> </tr></table></body>
