IoT-based Versatile Platform for Precision Farming

This paper presents the use of IoT (Internet of Things) in agriculture such as smart or precision farming. The versatile controller is developed to monitor and control temperature and relative humidity in different ways to serve different types of use. Control methods including timer, hysteresis control, condition control, can he arranged in different sequences and periods of time. Eight multifunction output ports are available for actuators or loads. Results from real implementation are shown. Temperature and humidity in a greenhouse can be controlled in predefined ranges to suit with planting processes. Data on the cloud can be monitored in real-time on PC or mobile application.
