Sledenje aktivnosti na kolesu s pomočjo mikrokrmilnika ESP32

diplomsko delo

Alen Granda (Author), Aleš Holobar (Mentor)

Abstract

Namen diplomskega dela je bila predstavitev energijsko varčne, a vseeno natančne alternative signalom globalnega pozicioniranja GPS, ki se ponavadi uporabljajo za sledenje aktivnosti na kolesu z uporabo mobilne aplikacije. Najprej smo predstavili trenutno stanje na trgu in opisali, zakaj smo se odločili poiskati alternativo. Implementacija naše rešitve je zasnovana s pomočjo magnetnega senzorja, ki na vsak vrtljaj kolesa pošlje signal mikrokrmilniku ESP32. Le‐ta filtrira, obdela in periodično pošilja pridobljene podatke uporabniški aplikaciji, kjer se vizualizirajo. Prav tako je na mikrokrmilnik povezan senzor za temperaturo, vlago in pritisk, ki nam omogoča izračun trenutne nadmorske višine s pomočjo barometrične enačbe. Omenjeno rešitev smo testirali z vožnjo kolesa po cesti ter analizirali pridobljene rezultate. Odstopanje med referenčnimi vrednostmi in našimi meritvami je do 5 % oziroma do 10 % v primeru izračuna nadmorske višine, medtem ko je poraba energije vsaj 3‐krat manjša v primerjavi s konkurenco na trgu.

Secondary title:	Cycle activity tracker using ESP32 microcontroller
Secondary abstract:	The aim of the thesis was to introduce energy‐efficient however accurate alternative to GPS signals which are primarily used to track activity on bike using mobile application. We began with introducing existing solutions on the market and describing why we decided to search for alternative solution. Our solution is based on hall effect sensor which dispatches signal to ESP32 microcontroller on every wheel round trip. Microcontroller filters, processes and periodically transmits given data to user mobile application. In addition, we calculate altitude with help of temperature, humidity and pressure sensor and barometric formula. We tested our solution on road and analyzed the obtained results. The deviation between the reference values and our measurements is up to 5 % or up to 10 % in the case of altitude calculation, whereas energy consumption is at least 3 times lower compared with the competition on the market.
