A. Project Proposal Title:
Temperature and Humidity Monitoring System of House.
B. Project description:
This project consists of monitoring the temperature and humidity in the living room of a house
for both cases; when the AC is working, and when the AC is stopped and the window is opened
(Fig. 1). Knowing that this data with other data can be used to find the thermal comfort using
what is called Predicted Mean Vote (PMV) when the AC is working and widow is closed.
Fig.1
D. What is provided:
For cali
ation: raw data (in Volts) for both sensors. The co
esponding temperature will be
provided and the data sheet of the humidity sensor will be given (It can be found online as well).
Then after cali
ation, the raw data of the sensors will be provided for the following conditions:
1. When the AC is working and widow is closed
2. When the AC is stopped and the widow is opened
E. Tasks to do:
(Show all Steps for the following tasks and write MATLAB coding if any)
Filtering the data from noises (Show all Steps)
Cali
ate temperature sensor and find the standard deviation σ for given data sample.
Find the co
esponding humidity using: the datasheet of the humidity sensor and the value of the
co
esponding temperature. F. Sensors to be used:
The temperature sensor LM35 is shown in Fig.2, and the Humidity Sensor HIH-4030 is shown
in Fig.3

G. Tasks and Content of the report:
1. Experiment setup: Sensors (implementation circuit and related components)
2. Sensor Cali
ation
3. Uncertainty analysis (about e
ors)
4. Data display analysis
5. Discussion
6. Conclusion
H. Remark:
• You can use Excel, Matlab, or any other tool to display and analyze the data.
• This is a project, so you need to make reasonable assumption whenever required.
Lifelong learning skill is one of the major outcome of this project
