A room temperature controlling system design based on wireless transmission technology
Abstract:Temperature control is not only used in factory production, but also reflected in all aspects to that with the improvement people’s living quality hotels, plants and family life would make use of temperature controller, temperature control will be better serve the society.
This paper introduced a temperature control system chip-based temperature acquisition AD590, a single-chip AT89S51 act as the core. The system includes the hardware circuit design, software design feature with a temperature of collection, temperature display, infrared receiver remote control functions.
Completed the design of the hardware part of the temperature of the collection, temperature display, infrared receiver, data processing design. First of all hardware systems through the infrared transmission techniques need to be set to receive the temperature signal, and then collected through the AD590 temperature sensor the temperature at the time, and 8 LED display real-time collection of temperature values or set values of temperature, and then transmitted to the system core single chip AT89S51, output through the single-chip temperature control AT89S51 information on heating or cooling the outside world.
The system has good practicability which requirements of equipment of automation and intelligent.
