Abstract :

Health care facilities strived to maintain clean environment, but studies show that after disinfecting the surfaces and things on regular basis, 40% of infections are transmitted from contaminated things or surfaces to the other persons. However, new evidence suggested that significant reduction of bacteria and viruses can be achieved by using UV radiation. For people this could be a major stop for controlling the problem. To overcome this problem, virus bacteria fighter with UV radiation is the ideal solution for sterilizing anything you don„t want to use the chemicals on vegetables, currency notes, fruits, baby bottles, groceries, masks, keys, wallets, mobile phones, and many more. It is made with commercial grade materials and intensity bulb (UV-C source) Phillips bulb 8 watt. It can keep any of your things sanitized without the use of any harsh chemicals. This contains automated timer controller up to 30 minutes with auto shut-off facility. The user can set the required time by rotating the potentiometer provided in the circuit. When the timer is running, if the cover of the UV chamber is opened accidentally, the UV lamp will automatically shut down. This facilitates to protect us from the UV radiation.
