摘　　要：蓝牙4.0主要面向功耗需求极低、传输数据量小、使用纽扣电池供电的应用,可广泛地应用于医疗设备、工业控制、无线遥控、智能家居等领域。基于BL620-SA低功耗蓝牙模块给出了一种蓝牙无线温度计的设计方案。该方案采用BL620-SA以及热敏电阻采集环境温度参数,而后将采集到的参数利用低功耗蓝牙协议发送给智能终端计算并显示当前环境温度。该方案具有功耗低、测温范围广(-55~155℃)、无线传输、用户界面友好等特点,可支持IOS和Android两种系统的智能终端。Bluetooth 4.0 is aimed at applications involving low power consumption, small volume of data transmission and button-battery power supply. It can be widely applied to many areas such as medical equipment, industrial control, remote control, intelligence home and so on. The low power consumption Bluetooth module, based on BL620-SA, provides a design for wireless Bluetooth thermometer. In the design, surrounding there are collected using BL620-SA and thermistor. With Low power consumption Bluetooth protocol, the parameters are subsequently sent to an intelligent terminal for computing and displaying the current surrounding temperatures. The design features a wide range of advantages including low power consumption, extensive temperature detecting(-55~155℃), wireless transmission and friendly user interface. Meanwhile, it supports intelligent terminals with either IOS or Android system.
