經(jīng)濟(jì)型、1-Wire數(shù)字溫度計(jì)

DS1822數(shù)字溫度計(jì)在-10°C至+85°C溫度范圍內(nèi)具有±2°C的精度。數(shù)據(jù)采用2進(jìn)制補(bǔ)碼格式，具有9位至12位分辨率(用戶可編程)，通過1-Wire?串行總線讀取。\n\n DS1822提供溫控器功能，具有用戶可編程的過溫(TH)和欠溫(TL)門限，保存于片內(nèi)EEPROM中。當(dāng)測(cè)量溫度高于TH或低于TL時(shí)，器件將設(shè)置一個(gè)內(nèi)部標(biāo)志。如果無須溫控器工作方式，則TH和TL對(duì)應(yīng)的兩個(gè)字節(jié)EEPROM可用于通用的非易失性存儲(chǔ)器。\n\n 每片DS1822具有唯一且不能改變的64位硅序列號(hào)，該序列號(hào)可作為傳感器的總線地址。這允許多個(gè)DS1822器件連接到同一條1-Wire總線。D ? -10°C至+85°C溫度范圍內(nèi)具有±2°C精度\n? 測(cè)量溫度范圍-55°C至+125°C (-67°F至+257°F)\n? 9位至12位用戶可配置的分辨率\n? 1-Wire接口，僅需一個(gè)端口引腳用于通信\n? 具有64位唯一且不能改變的電子序列號(hào)\n? 多節(jié)點(diǎn)能力簡(jiǎn)化了分布式溫度檢測(cè)\n? 報(bào)警功能，具有用戶定義、且為非易失性的報(bào)警設(shè)置\n? 將溫度轉(zhuǎn)化為12位數(shù)字量，轉(zhuǎn)換時(shí)間750ms (最大值)\n? 測(cè)量溫度時(shí)無需外部元件\n? 3.0V至5.5V電源電壓范圍\n? 可選的\"寄生電源\"工作方式(從1-Wire總線獲取電源)\n? 3引腳TO-92 (DS1822)和150;
