Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (ultraviolet C or UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. UVGI is used in a variety of applications, such as food, air, and water purification. The effectiveness of germicidal UV depends on the length of time a microorganism is exposed to UV, the intensity and wavelength of the UV radiation, the presence of particles that can protect the microorganisms from UV, and a microorganism's ability to withstand UV during its exposure.

Recent studies have shown that UV short-wave radiation is capable of eliminating COVID-19, MERS, and SARS viruses at the hospital level, thus improving the cleanliness of the intensive care area, general medicine rooms and individual rooms.

Advantages of this project:


The price of the hardware components for this project is approximately $ 250 USD. This is a good design that can serve as a model to calculate the price of a larger device or with more lamps or with a reflector.

In the international market, What is the price of these robots?
