Application of Message Queuing Telemetry Transport (MQTT) Protocol in the Internet of Things to Monitor Mushroom Cultivation

Temperature and humidity control are required at the room of mushroom farming to get maximum results. The process of controlling temperature and humidity is currently and highly dependent on human labor. Therefore, human intervention is greatly affected. This paper discusses the existence of internet of things (IoT, hereafter) technology as a temperature and humidity controller by using the Message Queuing Telemetry Transport (MQTT, hereafter) protocol based on the publisher and supplier paradigm. The MQTT protocol was chosen because it has a faster data transmission rate than using The Hypertext Transfer (HTTP, hereafter) Protocol. Data transmission speed makes accuracy in controlling temperature and humidity more accurate. Therefore, it boosts the speed to ideal temperature and humidity. The tests in this study are conducted to analyze the rate of data transfer speed from the sensor to the ideal temperature conditions. It takes an average of 7 minutes in these conditions. Meanwhile, the ideal humidity condition requires an average of 6 minutes. The average time is the time required when the room temperature is at 34°C and the humidity at the room is above 90%. Thus, the MQTT protocol is able to control room temperature and humidity in process of mushroom cultivation. It can be concluded that dependence on human labor is able to reduce.
