In food industry, cold storage is a must. The main objective of this kind of storage is to preserving the raw foods within for a certain period of time. But, for lack of technology and ignorance about humidity and temperature effect on raw foods; many times, food safety is not maintained well enough. In this paper, the basic objective of this research is to mitigate the man monitoring and to develop an internet based real time monitoring of temperature and humidity using the very available DHT-11 sensor and ESP-8266 NodeMCU module. This paper also makes compact distinctions between conventional and the IoT based monitoring system of food storages.
