分辨率可编程设置的1-Wire数字温度计

DS18B20数字温度传感器提供9-12位摄氏度温度测量数据，可编程非易失存储器设置温度监测的上限和下限，提供温度报警。DS18B20通过1-Wire®总线通信，只需要一条数据线 (和地线) 即可与处理器进行数据传输。器件可以工作在-55°C至+125°C范围，在-10°C至+85°C范围内测量精度为±0.5°C。此外，DS18B20还可以直接利用数据线供电 (寄生供电)，无需外部电源。每个DS18B20具有唯一的64位序列号，从而允许多个DS18B20挂接在同一条1-Wire总线。可以方便地采用一个微处理器控制多个分布在较大区域的DS18B20。该功能非常适合HVAC环境控制、楼宇/大型设备 • 独特的1-Wire®接口仅占用一个通信端口\n\n• 内置温度传感器和EEPROM减少外部元件数量\n• 测量温度范围：-55°C至+125°C (-67°F至+257°F) \n\n• -10°C至+85°C温度范围内测量精度为±0.5°C \n\n• 9位至12位可编程分辨率\n\n• 无需外部元件\n\n\n\n\n• 寄生供电模式下只需要2个操作引脚(DQ和GND) \n\n• 多点通信简化分布式温度测量\n• 每个器件具有唯一的64位序列号，存储在器件ROM内\n\n\n\n\n• 用户可灵活定义温度报警门限，通过报警搜索指令找到温度超出门限的器件\n\n• 提供8引脚SO(15;
