iPONICS: IoT Monitoring and Control for Hydroponics

This paper presents the design, and implementation of an intelligent, low-cost IoT-based control and monitoring system for hydroponics greenhouses. The system is based on three types of sensor nodes: The main (master) node is responsible for controlling the pump, monitoring the quality of the water in the greenhouse and aggregating and transmitting the data from the slave nodes. Environment sensing slave nodes that monitor the ambient conditions in the greenhouse and transmit the data to the main node. Security nodes that monitor activity (movement in the area). The system monitors water quality and greenhouse temperature and humidity, ensuring that crops grow under the optimal conditions according to hydroponics guidelines. Remote monitoring for the greenhouse keepers is facilitated by monitoring these parameters by connecting to a website. The system is optimized for low power consumption in order to facilitate off-grid operation.
