Using of sensors and actuators in the greenhouse to capture different values allows for the control of the equipment, it can also be optimized for growth at optimal temperature and humidity of various crops planted. We use wireless sensor networks’ system by sending results to the cloud service, monitoring values, and devices’s controlling via smart phone. The results of this study are useful for growing crops not only in technical parts, but also in physical part; it was evaluated by questionnaire using technology acceptance model. Keywords: Wireless Sensor Networks Internet of Things Hydroponics 1 Introduction Technology can link everything to the Internet called the Internet of Things (IoTs). This means that the hu- man beings control any object using a wireless sen- sor network (WSN) which makes convenience to ev- eryday life. Technology can be applied in many fields such as home, city, wearable, industrial, health, retail, farming, etc. IoTs refer to the network of objects, vehi- cles, buildings, and other electronic detectors, as well as software for connecting networks to exchange data from sensors or actuators. IoTs can also make people aware of the environment and remote control over the existing network infrastructure. We can integrate the physical world into the computer system and virtual resources available on the internet to provide both value-added data and functionality for users. The trend of 2020 IoTs usage will increase by 50 billion object were expected to be connected in the IoT [1]. IoTs’ devices include RFID, sensors, and computer nodes. The system must have an internet connection that the devices can send data and receive results to communicate with each other. If there is no connec- tion to the Internet but there are also some models that can be connected to other IoTs’ devices. Bluetooth is also an option in many ways to connect devices to physical phenomena on networks [2]. At present, farmers need access to the existence of agricultural information and they have relevant knowledge in making decision and respond to infor- mation needs. In the agricultural sector, through the development of knowledge management systems and farmers’ information inquiries, they can be answered with the helpfulness of accessible multimedia as the application of technology. Agriculture was interested in improving access to technology. Promoting agricul- ture on several aspects in developing countries, tech- nology had crossed handles using wireless technol- ogy and networking to utilize energy and power con- sumption by equipment, which is helpful in the agri- cultural development. The development of technol- ogy in various domains had driven substantial inter- est according to rising investments by private sectors towards the growth of technology [3]. In this research, The greenhouse is the best experi- mental place of our study with the IoTs system as well as a closed viewing area. It was equipped with sensors and internal devices for easy operation to analyze [4]. * Nathaphon Boonnam, 31 Moo 6 Surat-Nasarn Rd., Makhamthae, Muang, Suratthani 84000 Thailand, +66(0)77-355-040 & nathaphon.b@psu.ac.th www.astesj.com 1006 https://dx.doi.org/10.25046/aj0203127
