Remote Monitoring of Surface Temperature and Moisture Content in Urban Greenhouse

Internet of things (IoT) is a system of interrelated computing devices with unique identifiers that has the ability to transfer data over a network without requiring human interaction. In this paper, an IoT based system is proposed for monitoring surface temperature (humidity and temperature) and moisture content inside a low-cost urban greenhouse. The proposed system consists of the integration of hardware and software parts, in which the hardware part includes a microcontroller and multiple sensors. The performance of three various soil moisture sensors when detecting moisture content of various growing media inside a low-cost urban greenhouse is presented as well. The network setup and web page development using the user-friendly Hostinger platform are discussed as well. The proposed system will enable reliable remote monitoring of the surface temperature and moisture content of growing media inside a low-cost urban greenhouse as well as eliminating the need for human intervention. The data collected by sensors can be used for predictive analysis to track the state of the system in general as well as equipment efficiency.
