Wireless transmission is an effective way to transfer the data far away, so people can apply the wireless transmission of highprecision temperature measurement system on the production environment for wireless transmission and operators can have access to the realtime temperature changes, thereby enhancing production efficiency. This design take AT89S52 monolithic integrated circuit as core temperature control system39。s way for the monolithic integrated circuit， and control NFR905 wireless data transmissionby the microcontroller to the temperature data. Automatically disarm the alarm display and overlimit alarm, then the use of infrared controller to adjust the simulation of airconditioning, to achieve the specified the article introduced this control system39。隨著射頻 、集成電路技術(shù)的發(fā)展，無線通信功能的實現(xiàn)更容易，數(shù)據(jù)傳輸速率更快，抗干擾能力更強(qiáng)，因此，許多應(yīng)用采用了無線傳輸技術(shù)。因此，無線傳輸是一種有效數(shù)據(jù)傳輸方式。 隨著計算機(jī)技術(shù)的發(fā)展和計算機(jī)技術(shù)在信號處理中的廣泛應(yīng)用，現(xiàn)代的測量系統(tǒng)在數(shù)字信號處理方面的能力也大大加強(qiáng)了，形成了數(shù)字化測量技術(shù)。具體來說，就是將溫度、濕度、氣體密度等物理
