ZigBee-based indoor oxygen concentration monitoring and control system

为了有效地防止室内氧气浓度异常,对人体造成损害,设计了基于单片机技术的室内氧气浓度监控制系统。STM32F103C8T6微处理器用作采集点电路控制芯片,控制室内氧浓度传感器采集数据,再通过ZigBee通信模块将采集数据发送给MSP430G2553微处理器进行处理,其中氧气浓度传感器作为室内氧气浓度监测工具,结合特定算法计算室内氧气浓度,并使用LCD1602液晶显示器实时显示氧气浓度。当氧气浓度处于不正常的范围内时,MSP430G2553微处理器控制换气扇开启使得室内外空气对流,以达到调节室内氧气浓度回归正常的目的。通过模型的实验结果表明,该系统性能稳定,采集精度高、应用范围广等特点,可有效用于学校、体育馆和医院等人口密集地区。

In order to effectively prevent the abnormal oxygen concentration in the room and cause damage to the human body, an indoor oxygen concentration monitoring system based on single chip technology was designed. The STM32F103C8T6 microprocessor is used as the acquisition point circuit control chip to control the indoor oxygen concentration sensor to collect data, and then send the collected data to the MSP430 G2553 microprocessor through the ZigBee communication module for processing. The oxygen concentration sensor is used as the indoor oxygen concentration monitoring tool, combined with specific The algorithm calculates the indoor oxygen concentration and displays the oxygen concentration in real time using the LCD1602 liquid crystal display. When the oxygen concentration is in an abnormal range, the MSP430 G2553 microprocessor controls the ventilation fan to open to convect the indoor and outdoor air to achieve the purpose of regulating the indoor oxygen concentration to return to normal. The experimental results of the model show that the system has stable performance, high acquisition accuracy and wide application range, and can be effectively used in densely populated areas such as schools, gymnasiums and hospitals.
