Smart Greetthings: Smart Greenhouse Based on Internet of Things for Environmental Engineering

A greenhouse aims to provide optimum light and protect plants from the adverse climate which delivers an optimum environment for plant growth. A smart greenhouse is built with capability in environment manipulation. The smart device is installed in the greenhouse consists of many sensors, which measures environment parameters, such as temperature and air humidity. One of the environmental key parameters is temperature. The device uses this parameter to provide proper temperature for plant growth. The measured data is sent to the data server by utilizing the Message Queuing Telemetry Transport (MQTT) protocol through the Internet of Things (IoT) architecture. The smart device has succeeded in measuring parameters and performed environmental engineering. The temperature and air humidity sensors have average error measurements with values of 0.9 degrees Celsius and 7.22 percentage. Moreover, the device has been successful in transmitting the measured data by using the MQTT protocol.
