Making such a remote control switch is very simple, even beginners can do it well, because this circuit is too simple, and it only requires a dozen components. The SCM is used as the processing chip, so the circuit is simple. The SCM uses PIC12F629, and the integrated remote control receiver uses TSOP1738, of course, if you do not find this type of receiver, you can use an alternative model, and the relay chooses 12V relay.

If you connect the phototransistor in this circuit, the collector of the phototransistor is connected with the positive potential, the emitter of it is connected with the negative potential. When there is no light irradiation, the current which flows through the phototransistor is the Iceo between the electrode and the emitter of the phototransistor, it is the dark current of the phototransistor: Iceo=(l+hFE)Icbo.
In this formula:
Lcbo--the saturated current between the collector electrode and base electrode;hFE--the DC amplification coefficient of the common-emitter.
The phototransistor has the higher sensitivity than the photosensitive diode.
