In this modern era of farming greenhouses and vertical farms plays a very vital role in our food supply chain, The main problem faced in this type of farming is handling of humidity levels inside the farms. Since these kinds of farms are closed structures the humidity and ventilation is provided with help of fans, ventilation pipes and humidifiers (coolers). The humidity levels are measured and monitored continuously using Atmega-328p micro controller. The coolers are programmed to fetch input from the user, User can pre-set the required humidity levels or he can monitor the humidity and temperature levels in the live display and set the required humidity levels. After fetching the information from the user, An electrically controlled switch is used to switch ON the cooler. The humidity levels are monitored by calculating the volumetric density of humid air in the room, The user set humidity levels and the monitored humidity levels are compared frequently for maintaining the humidity levels. Once the user set requirement is full filled the cooler switches OFF and it is automatically triggered when the humidity level drops lesser than pre set values by the user.
