Grating circuits using integrated circuit

Published:2012/8/14 3:16:00 Author:Ecco | Keyword: Grating circuits, integrated circuit | From:SeekIC

This circuit uses TAA293 as a threshold switch. 1KΩ resistor is used to adjust the value of the photoresistor and threshold of threshold switch. Two circuits are suitable for the occasions: the light intensity is greater than 1000lx ( Q end is in high level) , light intensity is less than 300lx ( Q end is in low level).
