Abstract
This project aims 1) to study the absorption efficiency of extracted oil from cellulose in different type
of plants. 2) to study the efficiency of extracted oil from cellulose in automatic aromatherapy
lamp. Firstly, extract the cellulose fibers from corn silk, coconut fiber, and pineapple fiber. Secondly
bleach the cellulose fibers with sodium hydroxide and hydrogen peroxide. Thirdly, dry the fibers in the
sun. Lastly, test the absorption efficiency of 3 types of oil which was extracted from corn silk, coconut
fiber, and pineapple fiber. The efficiency of those 3 types of oil is 61.53%, 70.58% and 75%
respectively. The cellulose sheet that absorbs the most essential oils were pineapple fiber. The cellulose
will be put in the lamp the has ESP8266 command broad kit which can enable/disable the emission of
the oil via Blynk mobile application. The sensors will be installed for measuring the moisture of
cellulose sheets. When the humidity level reaches the preset value, the command board kit will
automatically stop the aromatherapy pump. The cellulose pad will be diffused the soothing aroma of
the essential oils by pressing the command button in the mobile application.
