Agricultural greenhouse wireless monitoring node and method

The invention relates to an agricultural greenhouse wireless monitoring node which comprises a low-power-consumption single-chip microcomputer, a temperature and humidity sensor, a soil temperature sensor, a soil moisture sensor, an oxygen detecting part, a sunlight irradiation sensor, a relay, a ZigBee radio frequency transparent transmission module, a power supply part and a directive antenna. According to the other technical scheme, an agricultural greenhouse data monitoring and controlling method of the agricultural greenhouse wireless monitoring node is provided. The node capable of being used for agricultural greenhouse wireless remote monitoring is provided. The node can provide a new management approach for agricultural greenhouse planting. According to the node, common planting parameters of a greenhouse can be collected, and a means capable of remotely controlling greenhouse planting equipment is provided. A solar power supply and directive antenna transmission enhancement mode is adopted by the node, and the node can be arranged more flexibly. The node is simple in structure, low in cost, reliable in work and beneficial to being popularized in the greenhouse agricultural planting field of our country.
