Greenhouse monitoring system based on wireless sensor network

The utility model discloses a greenhouse monitoring system based on a wireless sensor network, which comprises a sensor group which is used for acquiring air temperature, air humidity, soil temperature, soil humidity, carbon oxide content and light intensity in a greenhouse, a wireless sensor node which takes a singlechip CC2430 as a core and can receive data from the sensor group and collect and upload the data to a gateway in real time, and a wireless sensor network gateway hardware platform which takes an ARM920T kernel-based 32-bit RISC microprocessor S3C2410A as a core receives data transmitted by the wireless sensor node through a Zigbee network and finishes remote communication of the gateway in an Ethernet wire transmission way and in a GPRS wireless transmission way provided by a double-frequency module MC39I. With the adoption of the wireless sensor node, a plurality of dense and flexible greenhouses environments are monitored in real time, various key factors of growth environments of plants are monitored, and dynamic management and wireless transmission are realized.
