Abstract: A remote greenhouse monitoring system based on WSN middleware was introduced in this paper. The WSN middleware, which was located between the operating system (hardware firmware) and applications, shielded the difference of various network protocols、 node operating systems and the hardwares and provided one uniform interface and a set of common services. Using the WSN Middleware, the various environmental factors, which impacted on the production of greenhouse crops, can be dynamically monitored at a remote site in real time, which improved the labor efficiency of greenhouse product.
