An Internet of Things Technology for Detection and Prevention of Mold

Abstract

The susceptibility of building materials to mold growth varies. Some are tolerant to high relative humidity in the ambient air without mold growth occurring, while others are less tolerant, and mold can grow in relative humidity as low as 75%. In the heat of summer, the damages from molds become serious due to the effect of temperature and humidity according to seasonal characteristics. In this study, a smart sensor technology based on Internet of Things for detection of mold growth in indoor/outdoor environment is presented. The developed system comprises a cloud-based web application that communicates with the sensing device, and a sensing device that comprises a case, an electronic circuit, microcontroller and sensors. The mold detection is performed by recording the 24/7 profile of temperature and humidity variations
