The Research And Design On Multiparameter Environmental Monitoring System Based On Intelligent Greenhouse

As a new crop planting technology, greenhouse has broken the traditional crop planting restricted in region, natural environment, weather and so many factors, plays an important role in the agriculture. The measure control system of greenhouse is the most pivotal and important part in achieving producing automation and high efficiency. Temperature, humidity, light, CO₂, and PH of soil are the most essential factors in the growth environment of the crop. Measure and control system can implements collecting and processing data of the above factors, in order to control and make a good environment for the growth of the crop. Therefore, researching and designing a kind of multiparameter environmental monitoring system that can measure temperature, humidity and light in the greenhouse has wide application in agriculture and other relative industry.Modern technology of sensor circuits, circuit and system, intelligent control and data transmitting is used in this text. A multiparameter environmental monitor system based on intelligent greenhouse is designed, the function of it include:It can collects, measures and displays the accurate data of multichannel air temperature, air humidity and light. The system works stably. The structure of it is simple.The system transmits the data using RS-485 bus in normal condition and wireless transceiver in special condition. Circuit is simple, costs lower, works well. It also can achieve long-distance monitoring in Internet or GSM short message.The system can be used in other non-electricity parameter measure system, only need to change the sensors.
