ABSTRACT
From the world health organization hunger map, the global hunger population is 821 million in 2020. Moreover, COVID-19 caused the lockdown of the city boundary and the local food supply is not enough for the demand in some small country. Urban farming can help to increase the local food supply. However, it is not cost-effective and not efficient to supply food. Only limited kinds of crops with low efficiency and high cost can be provided. In this research, a newly invented Aero-Hydroponic Agriculture System (AHAS) aims to provide one more source for local food supply by adopting IoT technology to increase productivity. AHAS provides two different layers that allow growing vegetables on the top layer and carbohydrates on the bottom layer. With this IoT system, the temperature, humidity, pH value of nutrient and growth rate of crops can be monitored by the sensors and those environmental parameters can be controlled to offer suitable conditions to grow the crops. As a result, around 75-85% improvement in environment control is achieved by AHAS. With AHAS, more food can be produced in a limited space for the urban farming application. © 2021 IEEE.
