My name is Tomáš Válek. I studied Information Technology (IT) at Brno University of Technology, where I graduated as IT programmer (more informations about my study program here). The IT field is one of my biggest hobby since I was a child. I concetrate mainly on mobile apps as freelancer, web development less as part-time.

My free time is filled with my friends, doing hiking and walking tours somewhere in the wild nature and I really like to dance too. My favourite dance is Bachata. Aside from this, I am really interested in healthy ways/diets of living, in good and balanced food and nourishment and Green Ways is one of them, for sure. Last but not least, to keep my life harmonious and fresh, I love to work on new interesting and meaningful projects which inspire people and give us more freedom.

Tracking Air Pollutants by Using Wireless Sensor Network

Device design | PCB design | PCB mounting | ČSN 73 6058 | 3 pcs of prototypes | 4 firmwares | C | ZigBit | ZigBee | USB-B | UART | JTAG | ISP | I2C | LPG | C3H8 | C4H10 | C6H6 | CO | NOx

In 2013

Final Thesis in PDF

This thesis discusses how to design and create a prototype of a device and how to implement a firmware as an embedded system. The main function is to wirelessly monitor an amount of pollutants concentrations like carbon monoxide and propane-butane in atmosphere. The main goal of the thesis is to allow vehicles with an engine gaseous fuel to park underground together with other non LPG cars and observe the standart rule: CSN 73 6058. The prototype of the device has been suggested to be used not only in collective garages but also in family houses. The device was successfully designed and programmed so that it can be produced in real-world conditions.
