In this project, we examined the effects of
the temperature and the humidity of the environment to the efficiency and productivity of the
First of all, I want to talk about some
basic concepts. Heat is a form of
energy measurable in terms of temperature by thermometers. In a natural
environment, human experiences a range from arctic cold to tropical heat. And the
temperature of the environment influences the body temperature.
temperature is one of the fundamental
characteristics of the indoor environment. It can be controlled with the
building and its HVAC system. HVAC
is the system of heating, ventilating and air conditioning.
According to researchers, the best indoor
temperature for daily living is 293 K, 20 ° C or 68 ° F. We call it the best
condition because the indoor temperature affects several human responses such
as thermal comfort, perceived air quality and performance at work. In this
study, we focused on the effects of temperature on performance at our school.
Latest researches shows that extreme indoor
environmental conditions can affect health and productivity in a negative way. So
engineers are interested in improving indoor environments and their effects to
increase efficiency. We collect the existing information and tried to get new test
informations on how temperature affects productivity and efficiency. Because when
we know more about these effects, they could be included into cost-benefit
calculations for the building design and operation.
In this thesis, our microcontroller-based
embedded system is designed to monitor the temperature and humidity values of
the environment. In addition to monitoring temperature and humidity, we can
control the heat index too. Heat index
is a combination of air temperature and relative humidity. It also called humiture too. We designed the system
using Arduino Nano microcontroller.
Arduino webserver monitoring system was programmed using the C programming language. The sensor data
is read and processed by Arduino and it is displayed to the user through the Gobetwino interface.
We create the embedded system in two parts.
System design was the theoritical part. This part describes explaining the use of the
Arduino microcontroller and how it is utilized in the embedded systems in
practical part. We create the design and architecture model in this phase.
part describes the temperature and humidity
monitoring system. This part of the project is divided into two parts: Hardware
and Software. Practical part includes the wiring diagram and the source code
and it was the phase we did implementation and testing.
DHT11 Temperature and Humidity
We get the measurements of the class via
Arduino Nano heat and humidity calculation device which we build and encode. We
use Arduino Nano, DHT11 humidity and
temperature sensor to build a small circuit for measurements and ESP8266 Wifi module and Gobetwino for getting the data and save
them in a txt format.
