Abstract.. For. there are some defects like complex construction, too many lines and difficult maintenance when using a cable monitoring system in greenhouse, a design of low--power greenhouse monitoring system based on ZigBee wireless sensor network technology is pro- posed. ThroUgh the energy consumption analysis of the various parts of the system, the sensor nodes are designed by using a kind of energy saving strategy, using low--power RF chip and smart switch chips on hardware designing, applying event--driven method to software writ- ing to prolong their sleeping time. This system is not only able to collect the greenhouse parameters such as illumination, air temperature and humidity, soil moisture and carbon dioxide concentration precisely, but also low power consuming, low--cost and easy to expand. Test re- sults verified the feasibility of the solution.
