Brezžični merilnik in prikazovalnik kvalitete zraka v zaprtih prostorih

REMŠKAR, BLAŽ (author), Perš, Janez (mentor)

Zrak v notranjem okolju je v večini primerov onesnažen mnogo bolj kot zunanji zrak. Zato smo se z ekipo odločili ustvariti preprosto napravo, ki spreminja barve glede na kvaliteto zraka v notranjem okolju. Naprava, ki smo jo izdelali, vsebuje različne senzorje in barvno LED-diodo za prikazovanje stanja kvalitete zraka po barvni lestvici: od modre za čist zrak pa vse do vijolične za onesnažen zrak. Poleg tega je naprava opremljena z brezžično povezavo s pametnim telefonom preko tehnologije Bluetooth Low Energy. Napravo smo širši javnosti predstavili na tekmovanju iTime Startup, Slovenskem forumu inovacij in naši spletni strani. Prve primerke naprave smo želeli prodati na platformi za množično financiranje Kickstarter. V začetnem delu diplomskega dela je opisana celotna problematika kvalitete zraka. V nadaljevanju so predstavljeni nekateri senzorji za merjenje kvalitete zraka v notranjih prostorih in njihovo delovanje. Osrednji del prikazuje potek razvoja naprave od prvih prototipov do izdelka na tiskanem vezju. Na koncu je predstavljena implementacija komunikacije med pametnim telefonom in opisano napravo.

• Title: A device for wireless measurement and display of indoor air quality

Abstract

Indoor air is much more polluted than the air outside. That is why our team decided to create a simple device that changes color relative to the indoor air quality. The device that we created contains a variety of sensors and color LED for indicating the status of the air quality ranging from blue for clean air to violet for polluted air. In addition, the device is also provided with a wireless connection to a smartphone via the Bluetooth Low Energy technology. The device was presented to the general public at iTime Startup competition, Slovenian innovation forum and on our website. We wanted to sell the first pieces of the device on the Kickstarter crowdfunding platform. The initial part of the thesis deals with the problem of the air quality. After that, some sensors for measuring the quality of indoor air and a way of their functioning are presented. The main part describes the development process of the device from the first prototypes to the product made on printed circuit board. At the end the implementation of comunication between smartphone and the described device is presented.
