3、0構(gòu)成測溫系統(tǒng),并且通過無線收發(fā),最后在PC機(jī)上完成配置、顯示和報警的功能。在這次的設(shè)計中采用的單片機(jī)STC89C52RC的內(nèi)核和MCS-51系列單片機(jī)一樣,引腳也相同。但是STC89C52RC可以通過STC_ISP軟件下載進(jìn)行燒錄。無線數(shù)據(jù)通信收發(fā)芯片NRF24L01是一款工業(yè)級內(nèi)置硬件鏈路層協(xié)議的低成本無線收發(fā)器,工作于2.4GHz全球開放ISM頻段。此外,溫度傳感器DS18B20以"一線總線"的數(shù)字方式傳輸,可大大提高系統(tǒng)的抗干擾性。關(guān)鍵詞:SoC;STC89C52RC;NRF24L01;溫度傳感器DS18B2
