[[alternative]]System Development of Cell Culturing Device in Combination of MQTT Communication Protocol

[[abstract]] 本研究旨在設計一細胞培養裝置，除了可同一般培養箱調控環境參數外，額外增加了光的可調控參數，使照射受試物的光源可根據使用者需求來更換不同波長之LED光板，並透過調整輸入光板電壓與控制光板與受試物的距離來調整照度變數。本裝置是以Arduino Nano微處理器作為系統核心，負責接收裝置中各個感測器之回傳訊號，將其封包後再輸出顯示供使用者查看，亦可接收由不同裝置傳入的操作命令後，對培養箱內部進行環境參數調整。 本裝置共提供了三種調整介面，其包含主板本身實體介面、連接PC端之視窗程式以及行動裝置介面，彼此皆可即時且同步顯示當前培養箱之內部資訊而不相互影響，而其中的行動裝置是透過MQTT輕量化傳輸協議來實現，藉由簡單的設定即可使任何安裝MQTT相關APP的行動裝置皆成為本裝置的遠端監控介面。多樣化的操作介面得以讓使用者更加便利且彈性的使用培養箱。[[abstract]] The purpose of this research is to design a cell culture device. In addition to adjusting the environmental parameters same as a common incubator, additional light adjustable variables are added. For example, the illumination light source can be replaced with different wavelength LED panels according to user needs, by adjusting the input light board The voltage and the distance between the motor control light board and the test object can control the illuminance variable. This device is based on the Arduino nano microprocessor as the core of the system. It is responsible for receiving the return signal of each sensor in the device, and then package it and output the display for the user to view. It can also receive operation commands from different devices. Adjust the environmental parameters inside the incubator. This device provides a total of three adjustment interfaces, including the physical interface of the motherboard itself, the window program connected to the PC and the remote mobile device, which can display the internal information of the current incubator in real time and synchronously without affecting each other. And among them, the remote control of mobile devices is achieved through MQTT. With simple settings, any mobile device with MQTT-related APP can become the remote monitoring interface of this device. The diversified operation interface allows users to use the incubator more conveniently and flexibly
