The photoelectric control trigger circuit

Published:2012/9/11 1:50:00 Author:Ecco | Keyword: photoelectric control , trigger | From:SeekIC

The circuit plays the raster control role of the relay switch. When the light is dimmed, the current output by phototransistor is about 8mA ( supply voltage is 8V ). When the illumination is over 50lx, the circuit flips, the output is 0. The limiting frequecncy of the circuit is 6kHz.
