Abstract

The main purpose of this proposed project is to develop a formaldehyde sensing that are simple design, low-cost production and environmentally friendly device. This sensing device can detect the amount of the concentration level in food since this chemical compound can be harmful to the humans if contents higher amount of formaldehyde. This proposed will use the glass substrate to transmitted light with a certain incident angle and critical angle. The light transmit through the glass substrate will affect the output voltage. Hence, to obtained a stable system the glass substrate is coated with Hydroxyethyl cellulose/Polyvinylidene fluoride (HEC/PVDF) and Agarose Gel while the length of glass also being optimized. Therefore, this proposed project is to fabricate glass substrate platform coated with Hydroxyethyl cellulose/Polyvinylidene fluoride (HEC/PVDF) and Agarose Gel for formaldehyde sensing application. The length of glass that effect the output voltage also been optically characterize and optimized. This project was validating the proposed experiment for formaldehyde sensing application. The output voltage is obtained from the simulation by using Arduino Uno
