The Agricultural Greenhouse Monitor System of Temperature and Humidity Based on Wireless Communication

This paper presents one kind of agricultural greenhouse monitor system of temperature and humidity based on wireless communication. The structure of this system and key techniques of hardware and software are introduced. The monitor system includes wireless temperature and humidity access and control unit and wireless control signal receiving unit. Using a micro intelligent sensor SHT10 which is controlled by MSP430F2274, the temperature and humidity can be monitored through 2.4 G wireless communication chip EM198810. Compared with the existing technology, the monitor proposed in this paper satisfies real-time demand of monitoring temperature and humidity, and warning, and can send actuator motor wireless control instruction according to the built-in algorithm automatically or manually. This will achieve the effective control of temperature and humidity in greenhouse, and facilitate greenhouse automated operation and management. In addition, the monitor also provides the RS232 communication interface for data transfer with super-ordination machine. PC can acquire historical data of temperature and humidity on the monitor through RS232 interface, for further research and analysis of professionals.
