Temperature and humidity are two important factors to the crops growth and product quality in greenhouse. A study on the space-time distribution of humiture in greenhouse is required. The green house humiture monitoring system based on ZigBee wireless sensor networks (ZWSN) is the best solution. The objectives of this study are: (1) to develop ZWSN nodes for measuring the temperature and humidity in greenhouse; (2) to program suitable software making the nodes sleepy without work for energy saving; and (3) to optimize network performance by setting a time delay for each nodes. The designed system had been used to monitor the humiture inside a greenhouse. Experiments showed that this system operates stably, and the energy consumption was 22.4mA at work, 4.7mA in sleep. Its success rate of data packets reception was 97.1% with a delay. The ZWSN system could meet the need of humiture monitoring in greenhouse.
