摘　　要：蓝牙无线技术是使用范围最广泛的全球短距离无线标准之一,蓝牙4.0规范的核心是蓝牙低功耗(BluetoothLow Energy)技术,本设计采用基于BLE技术的CC2540芯片,利用SHT11数字温湿度传感器来进行温湿度的采集,并通过CC2540以无线方式将采集到的数据发送给监控终端。实验结果表明,本系统具有体积小、功耗低、精度高等优点。Bluetooth wireless technology is one of the global short-range wireless standards widely used. The core of the Bluetooth 4.0 specification is Bluetooth low Energy technology. The design uses CC2540 chip based on BLE technology,and uses digital temperature and humidity sensor SHTll for data collection to send the data collected by Bluetooth module CC2540 to the monitoring terminal through wireless waves. Experimental results show that the system is small with low power consumption and high precision acquisition.
