基于ZigBee的無線溫度變送器

ID:81961 · 發(fā)表于 2018-6-29 10:23

臨近畢業(yè)，有朋友找我?guī)兔ψ鰝€(gè)無線溫度變送器，想到大學(xué)四年就這么過去了，到最后其實(shí)沒學(xué)到什么真正的看家手段，有些遺憾，但是做點(diǎn)簡單的制作還是沒有問題的。于是就動(dòng)手，順便發(fā)個(gè)帖。
系統(tǒng)的功能是，利用pt100熱電阻采集溫度數(shù)據(jù)，利用電阻電橋來獲取準(zhǔn)確的電壓值，利用AD轉(zhuǎn)換芯片tlc549進(jìn)行AD轉(zhuǎn)換，然后將采集的溫度數(shù)據(jù)通過ZigBee模塊發(fā)送到主機(jī)部分，利用LCD1602顯示，這里我是每分鐘對發(fā)送數(shù)據(jù)存儲(chǔ)一次，一個(gè)小時(shí)更新一次，也可以選擇片外存儲(chǔ)器，能夠容納更多的數(shù)據(jù)。

制作出來的實(shí)物圖如下：
