Intelligent Micro-Incubator System Design for Temperature Control and Abnormal Alarm

Abstract

In this study, the STC89C51 microcontroller serves as the primary control unit, complemented by an LCD1602 display, a DS18B20 temperature sensor, and an active buzzer. The resulting intelligent incubator system is capable of maintaining a constant temperature and issuing real-time alerts in the event of temperature deviations. Additionally, users have flexible control over the incubator's temperature settings. The design of this intelligent incubator system is divided into two main components: hardware and software.On the hardware side, the STC89C51 microcontroller is employed to efficiently manage and drive the module circuits, facilitating the flexible acquisition and conversion of external data pertinent to the incubator system. For the software component, the control program is developed in C language, enabling the microcontroller to perform the desired functions. The overall design is systematically divided into the hardware circuitry and the software programming, with a modular design approach adopted to simplify the system's components. This method allows for step-by-step design and ultimately ensures that all functional requirements of the intelligent micro-incubator system are met.
