傳感器的定義

傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)實際上是一種(zhong)功(gong)能(neng)塊(kuai)，其(qi)(qi)作用是將來(lai)(lai)自外界(jie)的(de)各(ge)種(zhong)信(xin)(xin)號(hao)(hao)(hao)轉換(huan)(huan)成電(dian)(dian)(dian)信(xin)(xin)號(hao)(hao)(hao)。傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)所檢(jian)測的(de)信(xin)(xin)號(hao)(hao)(hao)近(jin)來(lai)(lai)顯著地增加(jia)，溫濕度傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)，因而其(qi)(qi)品種(zhong)也極其(qi)(qi)繁多(duo)。為了對各(ge)種(zhong)各(ge)樣的(de)信(xin)(xin)號(hao)(hao)(hao)進(jin)行檢(jian)測、控制，就必須獲(huo)得盡量簡單易(yi)于(yu)處理的(de)信(xin)(xin)號(hao)(hao)(hao)，這樣的(de)要求只有電(dian)(dian)(dian)信(xin)(xin)號(hao)(hao)(hao)能(neng)夠滿(man)足。電(dian)(dian)(dian)信(xin)(xin)號(hao)(hao)(hao)能(neng)較(jiao)容易(yi)地進(jin)行放大、反饋、濾波、微(wei)分(fen)、存貯、遠距離操作等。因此作為一種(zhong)功(gong)能(neng)塊(kuai)的(de)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)可狹義的(de)定義為：“將外界(jie)的(de)輸(shu)入(ru)信(xin)(xin)號(hao)(hao)(hao)變換(huan)(huan)為電(dian)(dian)(dian)信(xin)(xin)號(hao)(hao)(hao)的(de)一類元件。”傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)的(de)特(te)點包(bao)括：微(wei)型化(hua)(hua)、數字化(hua)(hua)、智能(neng)化(hua)(hua)、多(duo)功(gong)能(neng)化(hua)(hua)、系統化(hua)(hua)、網絡化(hua)(hua)。

傳感器的定義

傳感器是(shi)一種設備、模塊或(huo)子系(xi)統(tong)，其目的(de)是(shi)檢測環境中(zhong)的(de)事件或(huo)變(bian)化，溫濕度(du)傳感器公司，并將信息(xi)發送給其他電子設備，通常(chang)是(shi)計算機處(chu)理器。

傳(chuan)(chuan)感(gan)器(qi)是一種檢(jian)測裝置，能(neng)感(gan)受(shou)到(dao)被測量的信(xin)(xin)息(xi)，并能(neng)將感(gan)受(shou)到(dao)的信(xin)(xin)息(xi)，按一定規(gui)律變換成為(wei)電(dian)信(xin)(xin)號或其(qi)他所需形式的信(xin)(xin)息(xi)輸出，以(yi)滿足(zu)信(xin)(xin)息(xi)的傳(chuan)(chuan)輸、處理、存儲、顯示、記錄和(he)控制等(deng)要求。通常根據(ju)其(qi)基本感(gan)知(zhi)功能(neng)分為(wei)熱敏(min)(min)元(yuan)(yuan)(yuan)件(jian)(jian)(jian)、光敏(min)(min)元(yuan)(yuan)(yuan)件(jian)(jian)(jian)、氣敏(min)(min)元(yuan)(yuan)(yuan)件(jian)(jian)(jian)、力敏(min)(min)元(yuan)(yuan)(yuan)件(jian)(jian)(jian)、磁(ci)敏(min)(min)元(yuan)(yuan)(yuan)件(jian)(jian)(jian)、濕敏(min)(min)元(yuan)(yuan)(yuan)件(jian)(jian)(jian)、聲敏(min)(min)元(yuan)(yuan)(yuan)件(jian)(jian)(jian)、線(xian)敏(min)(min)感(gan)元(yuan)(yuan)(yuan)件(jian)(jian)(jian)、色敏(min)(min)元(yuan)(yuan)(yuan)件(jian)(jian)(jian)和(he)味敏(min)(min)元(yuan)(yuan)(yuan)件(jian)(jian)(jian)等(deng)類

傳感器

多種傳(chuan)感(gan)器(qi)(qi)可(ke)以(yi)(yi)(yi)用(yong)(yong)(yong)于(yu)智能農業(ye)，包(bao)括監測光，濕度，溫(wen)濕度傳(chuan)感(gan)器(qi)(qi)價格，溫(wen)度，濕度等的(de)傳(chuan)感(gan)器(qi)(qi)。利(li)用(yong)(yong)(yong)這些傳(chuan)感(gan)器(qi)(qi)，農民可(ke)以(yi)(yi)(yi)向(xiang)農作(zuo)物上均勻地施用(yong)(yong)(yong)和水。因此(ci)，溫(wen)濕度傳(chuan)感(gan)器(qi)(qi)設(she)備，終降低了成(cheng)本并(bing)消除(chu)了一些人工(gong)干預。物聯網在農業(ye)環境中的(de)另(ling)一大用(yong)(yong)(yong)途是監視牲(sheng)畜。農民可(ke)以(yi)(yi)(yi)利(li)用(yong)(yong)(yong)無線傳(chuan)感(gan)器(qi)(qi)監視牲(sheng)畜的(de)位置(zhi)，生命和飲食。這不(bu)僅可(ke)以(yi)(yi)(yi)為(wei)農民節省大量(liang)時間，還可(ke)以(yi)(yi)(yi)提(ti)供(gong)大量(liang)數(shu)據以(yi)(yi)(yi)保持農場健康。
