Design of micro-climate data monitoring system for tropical greenhouse based on Arduino UNO and Raspberry Pi

The change in global climate has shown us the importance of sustainable environmental monitoring, especially the microclimate in greenhouses. Monitoring is carried out to determine greenhouse data, which differs from outdoor. Internet of Things (IoT) as emergence technology has an important role in collecting microclimate data, IoT is developed using hardware, sensors and software connected to the internet network. This paper implements this by using Arduino UNO, Raspberry Pi, DHT11 microclimate sensor to gain microclimate data and store it in cloud applications. Microclimate changes are recorded every minute and displayed on a web page so it can be analysed without visiting the greenhouse. The test results showed that the data recording was successfully carried out, and the microclimate data analysis showed that in the greenhouse there was a weak association between temperature and relative humidity with an R squared of 0.534.
