With the rapid development of computer technology, MEMS technology, network technology, and so on, sensors are becoming miniaturization, intelligence, and integration, and has bring out a new network—Wireless Sensor Networks(WSN). Based on the existent CAN-bus measure and control system which can achieve automatic measure and control of the greenhouse environment and nutrient solution in our lab, this paper studies wireless sensor networks, mainly including multifunctional wireless sensor nodes, wireless control nodes, main node, and system integration demonstration. We design and study the wireless sensor networks node's hardware platform deeply, consider low-power characteristics in node hardware and software design, analyze the consumption of the node generally and give out the corresponding energy-saving strategies supplied with solar power and battery, and compose star networks. The results of the experiment in the greenhouse environment show that the wireless sensor network will bring a lot of convenience for the greenhouse environment monitoring and control.
