Intelligent home temperature and light control system based on the cloud platform

Compared with traditional home appliances, the high cost of purchase and maintenance of intelligent home appliances is becoming the fatal defect of the popularization and development of intelligent home appliances. In this paper, Intelligent Control System based on Alibaba Cloud platform is designed for traditional home appliances. The master control MCU chip HaaS1000 is equipped with dual-core Cortex-M33, combined with the temperature and humidity sensor to perceive the home environment. The infrared module installed with XK2233 chip and air conditioning coding library is used to control the air conditioning. The relay is used to control the lighting and the motor is used to control the curtain in the home. The system accesses to Internet via WI-FI and communicates with the cloud platform using MQTT protocol. Data is transmitted in JSON format between the MCU and the cloud platform. Users can browse the home environment data and control the working state of smart home through APP. The experimental results show that the system can run stably, which is a low-cost solution to the intelligent transformation of traditional home, and to some extent can solve the problem of high replacement price of existing smart home appliances.
