Design and Implementation of CO2 Incubator to Study the Effect of Wi-Fi 6 Signals on Human cells

In order to study the effect of Wi-Fi 6 signals on human cells, the do-it-yourself (DIY) CO
₂
incubator with electromagnetic (EM) shielding is designed and implemented. To maintain the temperature level between 36-37°C and CO
₂
level at 5 % (50,000 ppm), the Arduino UNO r3 is used. The proposed CO
₂
incubator is compared with the commercial CO
₂
incubator by cell incubating test to confirm CO
₂
incubator's functions. To prevent unintentional effects from outside Wi-Fi signals, this paper proposes the EM shielding design using Ott's method [10]. From experimental results, it can be concluded that the cell incubating test result of the DIY CO
₂
incubator is similar to that of the commercial CO
₂
incubator, and the implemented EM shielding can reduce the 2.4 and 5 GHz Wi-Fi signals from outside up to 15 dB. Moreover, from the preliminary results of cell viability, it shows that there is no any significant effect of Wi-Fi 6 signals to WS-1 cell line.
