Abstract


Thailand is the top first leading grower and exporter of tropical orchids in the world. A fumigation chamber is an important process for export. However, the weakness of the chamber is the danger of methyl bromide leaking to the fumigation area and free space next to the fumigation chamber. It is risk of dispersing concentrated substances from fumigation by methyl bromide. Methyl bromide is odorless and colorless. Workers and those involved may get poison from methyl bromide. The key objective of this research was to develop a cheap sensor for detecting methyl bromide. The results showed that the developed signal sensor module is as effective as a commercial device. The tendency value is only 5 percent different.
