Abstract
With the development of reform, opening up, and modernization of China's increasingly, agriculture and modernization of China's agricultural development must go this road, along with the rapid development of the national economy, China is a agricultural country, agricultural research and the application of more and more attention, particularly greenhouse has become an important component of efficient agriculture. How to increase greenhouse greenhouse crop production become pressing problems, scientific monitoring and control in greenhouse environmental parameters has become the trend of the development of modern agriculture.
This design uses C8051F340 MCU, DHT11, TGS4160, carbon dioxide sensor, temperature and humidity sensors nRF24L01 module wireless communication, design information capture and display of temperature, humidity and carbon dioxide concentration data long-distance transmission system using wireless communication modules, Terminal through the PC display. In achieving greenhouse monitoring system of temperature, humidity, carbon dioxide concentration, solve greenhouse human experience issues such as error, long reaction period of evaluation.
The system reliable, low cost. Systems through the collection of parameters of temperature and humidity in the greenhouse,and will receive the parametersdisplayed on t
