How do photosensors work
WebJun 17, 2014 · The longer the time, the farther away the object. Ultrasonic proximity detectors are good for measuring short distances (maybe a couple yards). It's usually up to the microcontroller to do the counting and distance computations; the detector takes care of sending and detecting the ultrasonic pulses. Accelerometer. Accelerometers are cool. WebPhotodiode: "A photodiode is a type of photodetector capable of converting light into either current or voltage, depending upon the mode of operation." Add Tip Ask Question Download Step 3: Sensing All you have to do is hook up the multimeter to read the voltage coming off the LED, that's it!
