This is the light fence schematic diagram uses LDR as the light sensing. The fundamental issue with the greater part of standard light sensors is that they require exact arrangement of light bar to quiet the […]

Dark and Light Activated Relay
This is the basic dark and light sensor which using photoresistor as sensing component. The transistor act like as a switch, when the “switch” in on condition then the relay will be activated.
Color Detector
This is the color detector / sensor circuit diagram. This circuit will sense eight colors that are: green, red and blue (as primary colours); magenta, cyan and yellow (as secondary colours); and black and white. It’s […]
