Abstract:

This article mainly introduces the AT89C51 single-chip as host controller, temperature and humidity sensors as the main external components of vegetable greenhouse control system. The system uses AT89C51 single-chip acquisition and processing, monitoring control, and environmental value of the output display for the growth of vegetables to provide a stable environment places. Besides, the system uses a low-cost and stable performance components for implementing high performance. 

Key words: AT89C51 single-chip, sensors, electric circuit of display, real-time monitoring
