basically its sort of a proximity sensor circuit, using a potential divider, the voltage reading should change with the distance between the laser and the photodetector. i have to complete a full plan before being able to experiment myself, so i need to know which photodetector would sense a...
hello, I am currently working on a simple school project to make a sensor circuit. i need the circuit to include a photodetector (either photodiode, phototransistor or LDR) to sense and measure the intensity of a typical laser beam (from a cheap laser pointer), the main aim is to get a different...
