Temperature iButton

iButton DESCRIPTION The DS1920 Temperature iButton provides 9-bit temperature readings which indicate the temperature of the device. Information is sent to/from the DS1920 over a 1-Wire interface. Power for reading, writing, and performing temperature conversions is derived from the data line

iButton溫度記錄儀

iButton?溫度記錄器(DS1920)提供-55°C至+100°C范圍內(nèi)的直接數(shù)字化9位溫度讀數(shù)，增量為0.5°。iButton通過硬件端口接口使用1-Wire?協(xié)議與處理器進(jìn)行通信。端口接口提供物理鏈路并處理通信協(xié)議，使處理器能夠通過簡(jiǎn)單的命令訪問iButton資源。兩個(gè)字節(jié)的EEPROM可用于設(shè)置警報(bào)觸發(fā)器或存儲(chǔ)用戶數(shù)據(jù)。\n\n 該溫度計(jì)采用DS1920封裝，可以在惡劣的環(huán)境中測(cè)量溫度。與所有其他iButton器件一樣，DS1920具有唯一的序列號(hào)。1-Wire接口將數(shù)據(jù)輸出、地址和電源減少到一根線。借助唯一的序列號(hào)，多個(gè)1920可以共享同一條總線，由放置在不同部位的多個(gè)傳 ? 數(shù)字溫度計(jì)可在0.2s（典型值）內(nèi)測(cè)量-55°C至+100°C范圍內(nèi)的溫度\n\n? 零待機(jī)功耗\n\n? 0.5°C分辨率，數(shù)字溫度讀數(shù)為°C值的二進(jìn)制補(bǔ)碼\n\n? 訪問內(nèi)部計(jì)數(shù)器有助于通過插值提高分辨率\n\n? 將控制、地址、數(shù)據(jù)和電源減少到單個(gè)數(shù)據(jù)觸點(diǎn)\n\n? 器件生成的8位CRC可確保數(shù)據(jù)完整性\n\n? 8位系列代碼規(guī)定了DS1920與讀取器的通信要求\n\n? 借助特殊命令集，用戶可以跳過ROM部分并同時(shí)為總線上的所有器件執(zhí)行溫度測(cè)量\n\n? 2字節(jié)EEPROM可用作警報(bào)觸發(fā)器或用戶存儲(chǔ)器\n\n? 警報(bào)搜索會(huì)直接指示哪個(gè)器件檢測(cè)到觸發(fā)警報(bào)的溫度;
