An IoT application for environmental monitoring and control using Raspberry-Pi

Abstract

Raspberry Pi hardware board is an economical Internet of Things (IoT) hardware platform that can be used for wide variety of applications. This paper discusses the hardware, software platforms and implementation details of an IoT application for environmental monitoring and control using Raspberry PI 3 Model B. The DHT11 sensor is used to monitor temperature and humidity to further control the air conditioning system. The FC-37 sensor is used to detect the rainfall and further control the sprinkling system. The MQ135 sensor is used to detect the presence of hazardous gasses in the environment. Django web technology platform is used to design a dashboard for monitoring and controlling the things. MySQL database is used to log the sensor data and Fusion charts are used to display the trends in graphical form.
