Monitoring temperature, humidity and controlling system in industrial fixed room storage based on IOT

Humidity and temperature monitors have wide industrial applications in many areas such as automobile industry, food processing and evaluation of plastic encapsulations in IC packaging. However, most of these monitors had limited functionality. Hence, this paper was proposed new features that can detect, notify, record and control the humidity and temperature instantaneously in order to have stable, controllable atmospheric conditions. This research was used of temperature humidity sensor DHT-11 to detect level of humidity and temperature changes inside the room. The data and information from DHT-11 sensor will be analysed graphically on Blynk platform using NodeMCU. Humidifier will be attached at this monitor to stabilize back the atmospheric conditions when a specific humidity level must be maintained to prevent static electricity build up, preserve material properties, and ensure a comfortable and healthy environment for workers or residents in industries. In this paper, the value of temperature and humidity changes can be seen through graph and gauge in Blynk software application. The relative humidity level will be decrease as the temperature increase. Humidifier triggered when the reading of temperature and humidity is less than 20% and more than 80%. Through the mobile application, it can review and read the previous readings and histories from the temperature and humidity sensor.
