[REVIEWED/TESTED] – Thirteen Different Optical Sensors For Measuring PWM With An Oscilloscope [WARNING, LONG POST]

. For my first BLF review – I decided to try a niche that hasn’t been covered before; optical sensors. A while back, I was intrigued by posts that showed oscilloscope screen captures of flashlight PWM. However, finding specifics on what sensor was used (and setup) was rather elusive. Therefore, I decided to test a variety of optical sensors to see which ones, if any, would work for measuring flashlight PWM with an oscilloscope (within a reasonable cost). I started out testing only two sen…
