Observed in the past greenhouses, people mainly have dealt with all problems by manual, but with the sharp increase in labor costs, this traditional greenhouse management model was facing a huge challenge. Traditional data collection for temperature and humidity mainly depended on the labor, leading to number of problems like heavy task, inefficient, labor costs higher and so on. According to the environmental parameter monitoring requirements in greenhouse, a wireless monitoring and controlling system for temperature and humidity is developed. It over comes the disadvantages of wired monitoring system, such as complicated wiring and difficult maintenance. The environmental parameters in every greenhouse were measured and controlled by micro-controller .The hardware and software of the monitoring system are discussed in detail. The experimental results show that the developed monitoring system has the following features, such as simple structure, high reliability, good extensibility and flexible c
