Rancang Bangun Alat Pendeteksi Formalin Pada Makanan Berbasis Arduino Uno

ABSTRACT Formalin is very dangerous for human health for we have to know whether a food contains formalin which is generally used to preserve food. For that we need a formaldehyde detector in food that uses an Arduino Uno as a control. The use of this project makes it easy to detect formaldehyde content without having to carry out laboratory tests. This tool uses the HCHO sensor as a device fo…
