Aplikasi Rangkaian Pengali Tegangan Walton Cockcroft Dan Sensor Af-30 Pada Penjernih Udara Ruangan Otomatis

Air is very important for all the living being in this planet, therefore good quality of air has to be maintained. The air quality in our office environment is much decreasing nowadays, due to human behaviour and life style, such as smoking and in return reduces our health. This reasearch proposes to design an air purifer to increase air quality inside a room. The propose air purifier applies Walton Cockcroft voltage multiflier with voltage output 4000-5000 Vdc to separate carbonmonoxide (CO) from oxigen. This device will work as soon as smoke sensor AF-30 detects carbonmonoxide in the air. This carbonmonoxide detection will result analog signal as the input to the programmed microcontroller ATMega 8535. The output signal of microcontroller ATMega 8535 will activate relay switch circuit and in the end will activate DC Motor fan, voltage multiplier circuit and exhaust fan. The voltage multiplier circuit output is 4420 volt DC at the 13th stage, this high voltage will ionize carbonmonoxide (negatif ion) from oxigen (positif ion). After positif and negative ion get separated, negatif ion would be outed by DC fan to the purifier element, the negatif ion would be the residue and stayed inside the purifier. It is hoped that this device would help in increasing air quality in side office room
