Abstract

The global problem is due to the anthropogenic and biogenic activities.This issue not only causes the global warming,but also the air pollution especially indoor environment.The emission of harmful gases which known as Volatile Organic Compounds (VOCs) are danger to human health,hence action is taken to purify the air.The purposes of doing this project study are to purify the indoor condition of a house by using own-made VOCs detector.HCHO sensor is applied in the VOCs detector in order to detect the VOCs concentration value with the aid of Arduino 1.8.3.One type of plants which is Mother-in-law’s tongue will be included in the study.The indoor plants are used to form a vertical house garden in a residual unit.The pre-test is conducted to investigate the sensitivity of the own-made VOCs detector for indoor, outdoor and non-circulation condition.First experiment is done to verify commercial products are containing poisonous particle and to show that the indoor plants are able to purify the contaminants.Then,second experiment is conducted to investigate the ability of selected indoor plants to purify the air for several days of time (one week).The collected data from these experiments are recorded and plotted as a graph of VOCs concentration values (ppm) against time (minutes).By plotting the graph,the data trends of VOCs concentration values either have an inclined or declined trend can be observed.
