Sustainable Agriculture and food security are dependent upon effective pest control in order to protect agricultural crops from the devastating effects of crop-destroying pests and the resultant reduction in crop productivity and economic loss. Traditionally, methods for controlling pests have often been applied based on abusing the environment of the planet, either through over-application of chemical pesticide products-with corresponding negative effects-or requiring human intervention through close monitoring of crops. The authors introduce an innovative IoT-based smart solution for those problems. The system includes built-in sensors for real-time environment condition monitoring, including soil moisture and temperature. A video camera module is also incorporated for visually identifying/diagnosing the pest problem in crop production. In addition, this system provides real-time alerting, automated irrigation based on the soil moisture content, and visual feedback through mobile applications and display modules to ensure that actions are taken to maximally enable timely and accurate intervention capability. The authors declare that IoT-based smart solutions facilitate the promotion of sustainable farming in terms of reduced use of chemical pesticides through effective efficiency in the operations of pest control as compared to conventional methods. Based on user feedback to date, it would appear that the IoT-based smart technology has saved time and labour and provided efficiencies for farmers. Hence, this study has demonstrated how IoT technology enables the application of sustainability in agriculture over the long term while at the same time promoting responsible environmentally friendly solutions for managing crop pests.
