Abstract:Cilj magistrske naloge je razviti in izdelati merilnik mase majhnih delcev, ki so škodljivi za zdravje ljudi in se nahajajo v zraku ki ga vdihavamo. Napajanje merilnika se vrši iz akumulatorskih baterij, ki se po potrebi polnijo iz zunanjega izvora energije. Izmjereni podatki o masi delcev iz zraka, temperaturi in vlažnosti zraka se prikazujejo na zaslonu, ter se odvisno od režima dela merilnika shranjujejo na spominsko kartico. Izmerjene podatke je možno s pomočjo serijske komunikacije prenesti na računalnik, seveda s pomočjo za to napisanega računalniškega programa. Merilnik mase majhnih delcev je sestavljen iz naslednjih medsebojno povezanih delov: napajalnih Li -ionskih baterij, enote za polnjenje baterij, enote za podnapetostno zaščtito baterij, časovnika za uro in datum, senzorja za merjenje temperature in vlage, enote za merjenje mase majhnih delcev, LCD zaslona, upravljalnih tipk, enote za shranjevanje izmerjenih podatkov, RS232 serijskega vmesnika in upravljalnega mikrokrmilnika. V nalogi so opisane nekatere od najbolj uporabljanih metod za merjenje velikosti, količine in mase majhnih delcev. Prav tako naloga vsebuje opis projektiranja in izdelave merilnika, katerega delovanje temelji na optični metodi prepoznavanja majhnih delcev. Umerjanje in rezultati meritev so prikazani tako tabelarično kot tudi grafično.
Keywords:Merilnik mase majhnih delcev, baterijsko napajanje, mikrokrmilnik, zaslon, spominska kartica, tipke, serijska komunikacija, temperatura, vlaga, čas, datum.

Title:Meter for small particle air pollution
Abstract:The aim of the master's thesis is to develop and produce a mass meter for small particles that are harmful to human health and are located in the air. The power supply of the meter is made from rechargeable batteries, which when needed, are charged from an external source of energy. Measured particulate mass data from the air, temperature and a humidity of the air are displayed on the screen. They can be stored on the memory card, depending on the working mode. The measured data can be transferred via serial communication to the computer with the help of the computer program. The small particle mass meter consists of the following interconnected parts: Li-ion batteries, battery charging unit, batteries under-voltage protection, clock and date timer, temperature and humidity sensor, units for measuring the mass of small particles, LCD screen, control keys, units for storing measured data, RS232 serial interface and microcontroller. The master thesis describes some of the most used methods for measuring the size, quantity and a mass of small particles. It also contains a description of the design and construction of the meter. The theoretical background of the optical method for identifying small particles is also explained. Calibration and measurement results are displayed both tabular and graphical.
Keywords:Small particle mass meter, battery supply, microcontroller, display, memory card, buttons, serial communication, temperature, humidity, time, date.
