摘要
设计并实现了一种采用能量优化、基于STM 300无线电模块的智能测量概念的自供电CO2传感器。基于能量采集技术,以太阳能板为供电核心,以STM300模块为控制核心,以GSS—COZIRCO2传感器为采集模块,实现了CO2传感器在光伏模式下的有效供电以及浓度的精确采集。针对传感器供电寿命短的问题,提出了一种利用其工作周期和低功耗关断模式平衡供电的动态功耗分析方法,并给出了长期试用下对于误差的自动校准方法。
A self-powered CO2 sensor based on energy-optimized,intelligent measurement concept based on STM300 radio module is designed and implemented.The sensor is based on energy harvesting technology,the STM300 module is used as the control core and the GSS-COZIR CO2 sensor as the acquisition module,the system is designed to achieve effective power supply and accurate concentration acquisition of the CO2 sensor in the photovoltaic mode.Aiming at the short service life of the sensor,a dynamic power consumption analysis method of balancing power supply with its duty cycle and low power shutdown mode is provided,and an automatic calibration method for the error under long-term trial is given.
