3 Meetup sorozat Segítnk megismerni a trendi Wireless technológiákat előadás sorozat 45 perc előadás / 15 perc demó Minden előadáson kisorsolunk egy develoment Kit-et Dedikált, magyar nyelvű fórum csatorna: Megosztani a tapasztalatokat Kérdésed van, elfelejtettél megkérdezni valamit a meetup-on: mérnökeink válaszolnak! SZERETNÉL valami másról is hallani? JELEZD a fórumon! VERSENY: Oszd meg IoT project ötletedet a magyar fórumon A legjobb ötletet 3 havonta díjazzuk a következő meetup-on: A technológiához kapcsolódó development kit-el és IC / modul mintákkal. 3 Silicon Labs Confidential

4 Soron következő témák (1/2) Április 28: Wireless technológiák - hogyan válasszam ki a megfelelőt? Demó: egyszerű garázsnyitó 15 perc alatt - lehetséges! Május 26: BLE technológia rejtelmei - hogyan tudok egy BLE eszközt fejleszteni mobiltelefonhoz Demó: ibeacon és egy BLE szenzor fejlesztése Nyárisznet, ősszel folytatjuk! Alacsony fogyasztású, embedded WiFi technológia bemutatása Demó: hogyan kldjk el a páratartalom és hőmérséklet értéket ben? Apple HomeKit: "Siri, turn on the light!" Demó: hogyan fejlessznk egy intelligens lámpát HomeKithez 4 Silicon Labs Confidential

5 Wi-Fi IoT Applications The Easiest Path to Native IoT Connectivity: Industrial/M2M Sensors Remote controls Smart Home Healthcare Fully integrated and secure modules for the energy sensitive Wi-Fi IoT applications 5 Silicon Labs Confidential

6 Adding a User interface to a device Screen and IO cabilities are expensive, but everybody has a smartphone and a tablet with them Using the Wi-Fi module, connectible by phones, tablets and computer, to create an user interface No app development overhead but the UI is displayed as a web page JSON parsing / HTTP GET PUSH Also supports App connectivity additionally to showing data on a web page Control, reading sensor data Build huge informative websites to be stored on the SD Card 6 Silicon Labs Confidential

7 We Help Developers Overcome These Challenges Connectivity Software & Tools Certifications Examples & Support HW + RF SDK & WSTK Getting to markets Reuse with pride! Modules are an all-inclusive deal with Faster time to market with Reduced risk 7 Silicon Labs Confidential
