Light-level-detector
If R, the sensor matching resistor, is equal to the "dark" resistance of the cadmium sulfide cell, the amplifier output will range from 0 to 2 as the light level varies from "dark" to "bright." The circuit operates similarly, but...
Light Sensitive trigger
All components have been placed on the PCB, but there is uncertainty regarding the connection of the power and load in relation to the relays.
The integration of relays into a printed circuit board (PCB) design requires a clear understanding of...
home-made light-operated camera trigger
This device is designed to capture images of moving objects by activating a camera or flashgun when one or two light beams are interrupted. Originally intended for photographing insects in flight, it can also be utilized for projectiles and other...
cut the feed forward in the miller compensation with voltage buffer
An internally compensated operational amplifier has been fabricated using n-channel Al-gate MOS technology, utilizing only enhancement mode devices. The circuit is designed to ensure that its performance remains insensitive to process parameters. The input stage consists of a source-coupled differential...
Arduino Light Sensors
A project is underway to determine the number of sun hours available at a specific location and to track this data over time as part of solar power installation design. The concept involves utilizing a light detector exposed to sunlight...
Light-operated switch
This circuit employs a flip-flop configuration utilizing Q1 and Q2. Under normal conditions, Q1 is heavily conducting. When light is detected by the CDS photocell, the bias on Q1 decreases, resulting in its cutoff, which activates Q2 and removes the...
Visible and Infrared Light Detectors
The sensors used are silicon phototransistors and Cadmium Sulfide (CdS) photocells. Both of these sensors allow less current to flow when they are dark than when lighted. Phototransistors change their conductance while photocells change their resistance depending on the intensity...
