摘要
为了显著降低有源RFID温湿度传感标签的功耗,设计了超低功耗有源RFID温湿度传感器标签。标签采用微控制器MSP430单片机为核心,以温湿度传感器SHT11和射频收发芯片nRF24L01为外围器件,完成温湿度的检测和发送。详述了温湿度传感标签的软硬件低功耗设计方法,以及功耗的测试与估算。该标签具有功耗小、成本低、运行可靠等特点,可广泛应用于光照、热和气流等环境能量供电的场合。
In order to significantly reduce the power consumption of the active RFID temperature sensing tag, an active RFID temperature and humidity sensing tag is designed. With the MCU MSP430 as the core, and the temperature and humidity sensor SHT11 and radio frequency transceiver chip nRF24L01 as its peripheral components, the tag accomplishes the temperature and humidity detecting and sending. The design methods of software and hardware to reach low power consumption, and the test and estimation of the power consumption for the sensing tag are described in detail. The tag features low power consumption, low cost, and reliability of operation, it is widely used in the power supply by environment energy, e.g. light, heat and airflow, etc.
