The application circuit of light triggered switch of Darlington phototransistor adopts the sub-type Darlington phototransistor and amplifier, so the weak light can flip the circuit.When the R1 and photodiode are reversed, or the in-phase and reversal phase input ends of the op-amp are reversed,the circuit can be modifiedas the darkness-triggered switch.
