Abstract

Air is one of the kinds of the gas group as the main source of breathing for the living things. In the air, there are many types of gases, but not all of them are good to be inhaled, one of them is carbondioxide. Carbondioxide is mostly produced by the vehicles, and it is also present in the car. Carbondioxide detectoris a safety tool used in the car. It is based on microcontroller and can be used to provide security to its users. The MQ135 censor detects carbondioxideby transmitting the data through the ATMega328 microcontroller whose concentration can be viewed through the LCD. Actuators in this study consisted of LED, buzzer, and servo motors as the power windows drivers. When the carbondioxide gas level exceeds the threshold of 1000 ppm, the LED that originally is in green will turn into red, the buzzer will be active and the servo motor will move to open the power windows. Conversely, when the carbondioxide gas level has returned to normal, buzzer will turn off and automatically power windows will close with the help of servo motor, and LED will turn back into green. The set of tool that has been made, compared to the carbondioxide gas detector in the room resulting error value of 3.11%.

二氧化碳探测器是一种基于微型控制器的内部安全装置

空气是生物赖以呼吸的主要气体之一。在空气中，有许多类型的气体，但并不是所有的气体都适合吸入，其中一种是二氧化碳。二氧化碳主要是由车辆产生的，它也存在于汽车中。二氧化碳检测仪是汽车上使用的一种安全工具。它以微控制器为基础，可以为用户提供安全保障。MQ135传感器通过ATMega328微控制器传输数据来检测二氧化碳，该微控制器的浓度可以通过LCD查看。本研究采用LED、蜂鸣器和伺服电机作为电动车窗的驱动器。当二氧化碳气体浓度超过1000ppm的阈值时，原本是绿色的LED会变成红色，蜂鸣器会活动，伺服电机会移动，打开电动窗。反之，当二氧化碳气体水平恢复正常时，蜂鸣器将关闭，并在伺服电机的帮助下自动关闭电源窗，LED将重新变为绿色。该套已制成的工具，与室内二氧化碳气体检测仪结果误差值为3.11%。
