Data Communication Design Based on Internet of Things Architecture for Smart Greenhouse Monitoring and Controlling System

Agriculture is an important economic sector in an agricultural country, such as Indonesia. In developing agricultural potential, there are many modern agricultural systems, one of which is the greenhouse system. The greenhouse is a planting system that can prevent plants from several factors that can cause damage to growth. Greenhouses interact with the surrounding environment and create a microclimate in the greenhouse. Changes in the microclimate are very influential for greenhouse cultivation plants. This paper provides a design of a two-way data communication system based on the Internet of Things (IoT) for monitoring and controlling smart greenhouses. Smart nodes can send microclimate readings to a remote database every 15 minutes. Users can control the actuators in the smart greenhouse remotely. Analysis and testing of the design of a smart greenhouse-based two-way data communication system were carried out by calculating the latency and packet loss data values. The average response latency of remote actuator control is 14.83 seconds. In sending microclimate data, smart greenhouses have an average latency of 14 minutes and 56 seconds with a packet loss percentage of 0%.
