  • Phototransistor Circuit Configurations & Applications ...

    Infrared light is composed of light radiation with wavelengths in the 700 nm to 1000 nm range, a little longer than visible red light, and therefore infrared light cannot be seen by the naked eye. The phototransistor operates as a bipolar transistor with light as the effective input to its base.

  • Infrared Detector Circuit using Phototransistor

    2021-6-5 · 6. I'm looking for a few hints in designing a light detector circuit. Priorities are that the circuit is simple (both as in few parts and as in relatively easy to understand), rather cheap, and can give a rough estimate of the light level. It should be able to clearly differ between night, early morning light, a cloudy day, direct sunlight etc.
