A remote wireless monitoring system for multi-parameters, including temperature, humidity, illumination etc., was researched based on the embedded chip and wireless transmission technology. The Spce061A was adopted as the core processor of the system, while the nRF905 was used for wireless transmission. Since the master-slave structure was adopted, the system could be configured flexibly and expanded easily. A monitoring software was also developed on the PC platform, so it is easy for upgrade. The whole system has a simple structure, stably performance and fine portability, and could work fast and exactly in some terrible condition.
