Detailed Description
Preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.
The utility model provides an intelligent illuminance circuit which comprises a voltage reducing circuit, a photoresistor, a key circuit, a distribution network indicating lamp, a power supply circuit, a doodling module, a temperature and humidity circuit and a ZTU module, wherein the power supply circuit is powered by a battery and outputs through capacitance filtering, the photoresistor is output from 3V to 2.5V through the voltage reducing circuit, and the distribution network indicating lamp is provided with a corresponding NPN triode.
The voltage reducing circuit comprises an LN1151B252SR voltage reducing chip.
The photoresistor is a PT3528 photoresistor, and the photoresistor is output from 3V to 2.5V through an LN1151B252SR buck chip.
In the utility model, the ZTU module displays the illuminance value on the mobile phone APP.
In the utility model, the power supply circuit is powered by a battery, the power supply circuit is output through capacitance filtering, the photoresistor PT3528 is output from 3V to 2.5V through the LN1151B252SR buck chip, and the change of illuminance and brightness of the resistor R6 is different when the photoresistor provides voltage. The stronger the illumination, the smaller the resistance of the photoresistor, the weaker the illumination, and the larger the resistance of the photoresistor. The sampling voltage acquired by the photoresistor is subjected to photoelectric conversion relation: (luminance/lux=1.978 sample voltage/mv-34) to obtain luminance value.
The ZTU module has weak self driving capability, and the distribution network indicator lamp is required to be driven by an NPN triode, and meanwhile, the current amplifying effect can be achieved. The key circuit enters a distribution network state after being pressed for 5 seconds, and the distribution network lamp plays a role in indication. Meanwhile, the SHT40 temperature and humidity sensor chip is newly added, so that the temperature and humidity values can be displayed.
The hardware function realizes that the illuminance value can be displayed on the mobile phone APP through the ZTU communication module, so that the illuminance can be monitored remotely. The value of the illuminance is sent to the APP in real time.
The utility model and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the utility model as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present utility model.
