Abstract

Na temelju bežičnog senzorskog čvora i projekta YAWN koji se radio u sklopu natjecanja Texas Instruments Innovation Challenge European Design Contest 2016 napravljena je analiza potrošnje senzorskog čvora koja uzima u obzir različite komunikacijske protokole, senzorske elemente i različite izvore napajanja. S obzirom na potrošnju senzorskog čvora projektiran je modul za prikupljanje termoelektrične energije kao nadogradnja na YAWN senzorski čvor. Sklop je optimiran te je ostvaren prijenos informacije s temperaturnog indikatora od mikrokontrolera putem RF modula energijom dobivenom iz topline ljudskog tijela, tj. dizajniran je senzorski čvor koji radi bez baterije. Kao nadogradnja na YAWN senzorski čvor, dizajniran je modul za detekciju pokreta temeljen na PIR senzoru. Modul s optimiranom potrošnjom može raditi na bateriji CR2032 i do 10 godina. Na kraju, dizajniran je poslužitelj također baziran na YAWN modulu, koji prikuplja podatke sa senzorskih čvorova i šalje ih putem USB sabirnice na procesiranje u MATLAB. Test rada cjelokupnog sustava izvršen je u prostoriji D-339-3 na ZEMRIS-u.

Abstract (english)

Based on YAWN wireless sensor node that was made within the Texas Instruments Innovation Challenge European Design Contest 2016, power consumption analysis of a sensor node is performed taking into account the influence of various communication protocols, sensor elements and power sources. Considering the power consumption a thermoelectric harvesting module is designed as an upgrade to the YAWN sensor node. The device is optimized and successful wireless transmission of the temperature sensor data is perfomed using energy received from the heat of the human body, i.e. a batteryless sensor node is designed. Also, the PIR motion detector is designed as an upgrade to the YAWN sensor node. This module with optimized power consumption can operate more than 10 years on the battery CR2032. The final task performed is the design of the server based on the YAWN module. This server collects informations from the sensor nodes and sends them via USB port to MATLAB for processing. Test of the whole system is performed in the room D-339-3 on ZEMRIS.
