Highly reliable wireless control system for tomato nutriculture

In the field of horticulture, various environmental control systems have recently been proposed and implemented. Some systems target cultivation of high quality vegetables and require reliable environmental and device control data reception such as nutrient solution control for tomatoes. However, leaves or metal pipes prevent wireless sensor networks (WSNs) from collecting environmental data or controlling devices. Therefore, in this paper, we propose a wireless control system for tomato nutriculture even in severe conditions. Implementing a highly reliable wireless control system using 429MHz band and two channel access mechanisms, we archived wireless communication without packet loss.
