Intelligent water dispenser system based on embedded systems

Using single-bus temperature sensor DS18B20 to measure real-time temperature of the drinking fountains, providing calendar and time through clock chip DS1302, receiving information from the remote through HS0038B, and displaying the calendar and time as well as the current temperature value through LCD12864, the system was designed based on microcontroller STC89C52. The system´s overall design concept, the hardware circuit and software flow chart and design, temperature error of processing and the use of fitting algorithm have been demonstrated. The system has such functions as remote control, temperature control, cooling, variable power heating, with a high level of safety, stability, intelligent control and low power consumption.
