This was a project for self-education purpose. I created a device to monitor climate.
Firstly, I want to thank Jonathan White for his evening lectures on Robotics at Lviv Polytechnic in far 2015. It was an honour to be a student of the lecturer from Harding University.
Like many other geeks, I am a big fan of science fiction: Isaac Asimov, Stanislaw Lem, Arkady and Boris Strugatsky, etc. Also, I really like the idea of automatic climate control in confined space.
Therefore, as a project aimed at broadening my skills, I decided to make a device that determines climatic parameters and displays them.
The device receives temperature and humidity from 2 points of the object under observation (room in the house, mini-greenhouse etc.) and calculates the average value of these indicators. Ideally, the measurements should be taken from the bottom and the top of the room.
To implement this project, I chose the following hardware:
- Arduino UNO;
- Nokia's 3110 screen;
- sensor STH21 (because of their high accuracy) x2;
- a set of cables.
In the work process, I faced a problem — as sensors had the same addresses, I didn't have access to both of them at the same time. I solved this problem by alternating questioning of sensors (with a frequency of 1 second).
As a result, I got a device that worked completely as intended. Also, I got praise from my friends who aren't connected with IT).
In general, robotics (I know that it's still far from it) truly fascinates so I hope that my portfolio will feature more projects associated with hardware and ML.
