Small projects and remarks on electronics * Wechsellichtschranke Uses PLL-IC NE567 to protect against stray light text/html 2024-09-29T07:35:30+00:00 Anonymous (anonymous@undisclosed.example.com) https://glaschick.de/rclab/en/elektronik/wechsellichtschranke?do=revisions&rev=1727588130 Proximity Sensor with PLL-IC By using the PLL IC NE567, only light of the frequency and phase sent is detected: R2 determines the sensitivity; if too large, strong stray light may overdrive the sensor. R3 and C4 determine the frequency and need only be changed if stray light of the same frequency is very strong.
