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温度记录仪

iButton®温度记录器(DS1920)提供-55°C至+100°C范围内的直接数字化9位温度读数，增量为0.5°。iButton通过硬件端口接口使用1-Wire®协议与处理器进行通信。端口接口提供物理链路并处理通信协议，使处理器能够通过简单的命令访问iButton资源。两个字节的EEPROM可用于设置警报触发器或存储用户数据。\n\n 该温度计采用DS1920封装，可以在恶劣的环境中测量温度。与所有其他iButton器件一样，DS1920具有唯一的序列号。1-Wire接口将数据输出、地址和电源减少到一根线。借助唯一的序列号，多个1920可以共享同一条总线，由放置在不同部位的多个传 • 数字温度计可在0.2s（典型值）内测量-55°C至+100°C范围内的温度\n\n• 零待机功耗\n\n• 0.5°C分辨率，数字温度读数为°C值的二进制补码\n\n• 访问内部计数器有助于通过插值提高分辨率\n\n• 将控制、地址、数据和电源减少到单个数据触点\n\n• 器件生成的8位CRC可确保数据完整性\n\n• 8位系列代码规定了DS1920与读取器的通信要求\n\n• 借助特殊命令集，用户可以跳过ROM部分并同时为总线上的所有器件执行温度测量\n\n• 2字节EEPROM可用作警报触发器或用户存储器\n\n• 警报搜索会直接指示哪个器件检测到触发警报的温度;
