This week-end I took part in the Raspberry Pi Hackathon. Except the fact that I needed 15 hours of sleep in order to recover from the time spent building the project, it was a wonderful experience both for beginners and the advanced ones in this field. I, my dad and two students from Electrical and Electronic Engineering department from Polytechnic University of Bucharest made an effective team and took part in the hardware section.
Purpose of the project: remote monitoring of a room or area where access is difficult or dangerous
Examples of use :
- monitoring parameters of comfort or safety through a web interface (it can be accessed also on the smart phone);
- regular use of sensors (temperature, humidity, pressure, wind, proximity, etc.);
- comfort control parameters by pressing a button ( floor heating, water pumps, sockets/lights, etc.);
- using a webcam with motion detection which sends pictures on a predefined email address.
2) professional use
- centralizing the aggregation parameters from distributed sensors (eg scattered mini weather stations)
- collecting data from mobile stations (video/audio, collections of various sensors) using a platform with wheels (line follower) controlled by Arduino which communicate with raspberry pi pyfirmata
- streaming video/audio
- Raspberry Pi sensor I2C or SPI
- Usb webcam
- Usb wi-fi (for communication with the mobile platform)
- Arduino Mega controller for 4 motors drivers and additional analog and digital sensors (IR, ultrasound)
- Arduino Uno controller for relays which control the sockets and lights
Here is the Git Hub source of the code.
During the contest, I was interviewed about our project for the news programme of the main TV channel in Romania:: http://stirileprotv.ro/stiri/ilikeit/inventia-romaneasca-realizata-in-24-de-ore-si-cu-doar-200-de-lei-cum-te-ajuta-cand-pleci-in-vacanta.htm
