[0045] Specifically, a phototransistor is a semiconductor photoelectric device whose current is controlled by external light. This type of transistor is similar in structure to connecting a photodiode between the base and collector of an ordinary transistor, where the current generated by the photodiode is equivalent to the base current of the transistor. Due to its current amplification effect, the phototransistor is more sensitive than the photodiode and can output a larger photocurrent at the collector. When light shines on the photosensitive window (i.e., the base) of the phototransistor, electron-hole pairs are generated. These charge carriers form a current under the action of the internal electric field, realize photoelectric conversion, and are amplified by the transistor, thereby outputting the amplified electrical signal at the collector. When there is no light, the phototransistor is in the cut-off state and no electrical signal is output; when exposed to light, the phototransistor is turned on and a photocurrent is generated at the collector. Phototransistors are usually used for the detection of optical signals, and can convert optical signals into electrical signals for subsequent processing.

[0048] The WIFI-based lamp control circuit provided by the embodiment of the utility model utilizes the characteristic that the spontaneous polarization intensity of pyroelectric materials generates charge movement as the external temperature changes, detects the change of infrared energy radiated by the human body in a non-contact manner, and then combines the collected changes in the external environment light, and converts it into an electrical signal to the WIFI Bluetooth module with its own MCU to achieve error-free triggering. That is, using the PIR module to detect the human body and combining it with the light sensing module to collect light, it can achieve the effect that there will be no false triggering when the external environment changes, and at the same time ensure that the light will turn on when someone passes by. The WIFI-based lamp control circuit uses the light sensing module to check whether the external environment is daytime or night, and then uses the PIR module, IC module and PIR probe to jointly monitor the human body, and finally uses the software algorithm to calculate and make a judgment on whether to turn on or off the lamp, so as to achieve the effect of turning off the lamp during the day and turning on the lamp when someone passes by at night.
