Indoor Ambient Temperature and Light Automatic Detection System

This paper designs an automatic detection system for indoor temperature and light temperature based on STC12C5A60S2 single-chip microcomputer. The whole system is composed of a host control module, a photoelectric detection module, an analog-to-digital conversion module, a temperature detection module, a voice broadcast module and a liquid crystal display module. The ambient temperature and light conditions are detected by the temperature sensor DS18B20 and the photoresistor, and the ISD1730 voice chip is used to realize the voice broadcast of the temperature value and the light condition. At the same time, the liquid crystal LCD 12864 is used to display the current temperature value and the illuminance value. The system has been tested to be stable, with low power consumption, small size and economical advantages.
