Chinese. 中国是人造板生产和消费大国,2010年产量已达1.53亿m3,连续多年位居世界第一（钱小瑜,2011）,人造板产品广泛应用于家具制造、室内装饰等方面,与人们的生活息息相关。然而90%以上的人造板生产过程中要使用脲醛树脂等含醛胶黏剂（顾继友,2006）,其产品在使用过程中会缓慢释放游离甲醛,威胁着人类的身体健康,甚至有致癌的危险。

In order to change the status of importing expensive equipment from abroad and fill the gap of no formaldehyde testing chamber domestic, this research developed a control system, which kept ATmega2560 as the core, applies fuzzy control arithmetic to control chamber temperature and relative humidity. The system has high stability and flexibility, and the cost was reduced by one third compared with PLC system. The result showed that the accuracy for temperature could achieve ±0.5℃ and that for relative humidity was less than ±3%.
