Applied internet of thing for smart hydroponic farming ecosystem (HFE)

In the present, Thailand is developing to fully apply the Internet of things (IoT) [12] into daily life because IoT is a new trend of the technology and it is very popular today. The IoT helps us link objects and mechanisms to the internet for remote control. In addition, Thailand focuses on agriculture because Thailand is an agricultural country and it is also the main occupation of people in the country, which makes agriculture have many formats in Thailand, but hydroponics [5] [11] is an interesting new format that uses less area than others. Although hydroponics uses less space than conventional planting, it can provide many products for the farmer. In hydroponic farming, it is difficult to plant and manage if you aren't a professional farmer or don't have good knowledge about farming. For some it can be very hard to do hydroponic farming. This paper will propose a Hydroponic Farming Ecosystem (HFE) that uses IoT devices to monitor humidity, nutrient solution temperature, air temperature, PH and Electrical Conductivity (EC). The HFE is made to support non-professional farmers, city people who have limited knowledge in farming and people who are interested in doing vertical planting in very small areas in the city such as building tops, balconies of small rooms in high-rise buildings, and in small office spaces. To make the system easy to control and easy to use, we have an android application to control IoT devices in the HFE and alarm users when their farm is in an abnormal situation.
