  • Photodiode/Phototransistor Application Circuit

    Working Explanation. This circuit works such that photoresistor, at first, will detect light. The base of the phototransistor is exposed to the environment. Thus, the photons from light strikes onto the base of the photoresistor. When there is no light, a signal is produced by the phototransistor that will trigger the 2N2222 transistor.
