IoT Planting: Watering system using mobile application for the elderly

Nowadays, Thailand has become an aged society. The elderly's mental health has decreased resulting from physiological changes. At present, technology has connect everything to the world of the Internet called the Internet of Things (IoT). IoT can be applied to many ways, which can improve the quality of life and reduce spaces between the elderly and technology. In this paper, we studied the situation of the elderly and proposed the IoT Planting which consists of gardening platform prototype with soil moisture, temperature, water sensor, grow light, and Android application for the elderly. An evaluation was performed by Technology Acceptance Model (TAM). The result represents that the elderly perceived the usefulness and found that it easy to use contrary to their expectations. Moreover, by reviewing their opinion, it was found out that they have a positive attitude toward our application and willingness to use it.
