MQTT Performance as a Message Protocol in an IoT based Chili Crops Greenhouse Prototyping

MQTT is an open source message protocol ideally used in machine-to-machine or Internet of Things. MQTT designed for limited devices, low bandwidth, and high latency system. MQTT provided with transmission assurance by using the QoS level in publish and subscribe mechanism. The aim of this research is to check the MQTT performance as an implementation of monitoring and controlling system. The system used in this research designed to be able to automate a greenhouse prototyping system and also to monitor and control greenhouses remotely. The case of this system is to automatically control and monitor chili crops in the greenhouse prototyping. This system used Wemos DI R2 board as a control center, SHTII sensor, YL-69 sensor, 16x2 LCD, RTC, relay, and Level- 0QoS MQTT communication protocol. The parameter used to check the MQTT performance are delay, throughput, and packet loss. The result showed that MQTT protocol is suitable for transmitting data in Internet of Things system. The average QoS parameter result changed based on the transmission speed in each network and the use of level 0 QoS on MQTT protocol.
