INTERNET OF THINGS TEMPERATURE DETECTION IN-HOUSE USING RASPBERRY PI

ABSTRACT

The revolution of the IT industry is in its ability to introduce automation to tasks that require human resources. The motivation for this project lies in the automation of a seemingly simple subject but if done incorrectly, can cost a company millions of naira in damage control and more millions to recover from. This project focuses on the temperature sensing built on an event-driven process. Event-driven processes are used all the time and in various scenarios, for example, the light in the fridge that turns on when the fridge door is opened Or the light bulb that turns on when the motion sensor senses motion. In this project, using a combination of two raspberry pi, a temperature sensor, and a light bulb, we build a temperature sensing system built on an event-driven process. This system is designed to detect the temperature of any room it is placed in, and raise an alert if the temperature readings become alarming. One obvious advantage of this project at this point is the “alert” system. Using the MQTT protocol, the two raspberry pi’s are able to communicate to each other over a local network or a network as large as the internet. Thereby allowing the “sensing” raspberry pi to notify the “alarm” raspberry pi of causes for alarm. Furthermore, to emphasize the usability of this project, a user-friendly website is developed. This website will graphically present to the user the temperature readings over a period of time, and not simply the current temperature. This allows the user to narrow his/her debugging parameters, or simply observe the temperature from a remote location. The light bulb attached to the alarm raspberry pi, notifies the user that an event has occurred and the automation process stepped in and executed the pre-programmed instructions. Using a number of programming languages, programming tools and real hardware devices, a fully functional event-driven temperature sensing system has been built and tested.
