2. THE CURRENT STATE OF THE INTERNET OF THINGS

3. “ ” - Nikola Tesla MOBILE, CIRCA 1926 When wireless

   is perfectly applied the whole earth will be converted into a huge brain, which in fact it is, all things being particles of a real and rhythmic whole… and the instruments through which we shall be able to do this will be amazingly simple compared with our present telephone. A man will be able to carry one in his vest pocket.

4. 34 BILLION Devices online by 2020 Spent on the IoT

   (2016-2021) $6 TRILLION

5. THE EVER-PRESENT GARTNER HYPE CYCLE PEAK OF INFLATED EXPECTATIONS TECHNOLOGY

   TRIGGER TROUGH OF DISILLUSIONMENT SLOPE OF ENLIGHTENMENT PLATEAU OF PRODUCTIVITY VISIBILITY TIME IOT TODAY IOT TOMORROW!

6. THE EXIT “THE TROUGH,” THE IOT MUST SOLVE REAL PROBLEMS

7. SMARTFIN

8. None

9. ENVIROFIT

10. FROM CLOSED TO OPEN

11. FROM CLOSED TO OPEN

12. IoT Solutions are about much more than embedded hardware &

    firmware

13. “THE IOT” IS A NEW, FOREIGN WORLD FOR MANY HARDWARE

    ENGINEERS What a typical hardware engineer understands today

14. JAVASCRIPT: THE COMMON DENOMINATOR

15. THREE TYPES OF IOT APPS 1 2 3 IOT WEB

    APPS IOT MOBILE APPS IOT CLOUD APPS

16. IoT Builders are the real full-stack developers

17. THREE TYPES OF IOT APPS 1 2 3 IOT WEB

18. HOW WEB APPS ENABLE THE IOT 1 IOT WEB APPS

    DATA AGGREGATION AND VISUALIZATION EXTENSIBLE AND PLATFORM-AGNOSTIC
19. None

20. OPTIONS FOR BUILDING IOT WEB APPS 1 2 GET DATA

    FROM YOUR DEVICES BUILD YOUR APP MQTT TCP Pub/Sub Particle Pub/Sub

21. PARTICLE PUBLISH AND SUBSCRIBE double tempC = 0; void setup()

    { Particle.variable("temp", tempC); pinMode(A0, INPUT); } void loop() { analogvalue = analogRead(A0); tempC = (((analogvalue * 3.3) / 4095) - 0.5) * 100; if (tempC > 120) { Particle.publish("temp/critical", tempC); } else if (tempC > 80) { Particle.publish("temp/warning", tempC); } } void setup() { !// Subscribes to temp/warning AND temp/critical Particle.subscribe("temp", handleTemp); } void handleTemp(const char *event, const char *data) { double temp = extractTemp(data); if (temp > 120) { deactivatePump(); } else if (temp > 80) { reducePumpSpeed(); } }

22. https://api.<your-iot-service>.com/v1

23. YOU NEED A GOOD API

24. THE PARTICLE DEVICE CLOUD API # API Call # GET

    /v1/events/{EVENT_NAME} # EXAMPLE REQUEST curl -H "Authorization: Bearer {ACCESS_TOKEN_GOES_HERE}" \ https:!//api.particle.io/v1/events/temp/critical # Will return a stream that echoes text when your event is published event: temp/critical data: {"data":"125","ttl":"60","published_at":"2018-05-28 T19:20:34.638Z", "deviceid":"0123456789abcdef"}

25. THE PARTICLE JS LIBRARY const Particle = require('particle-api-js'); const particleAPI

    = new Particle(); const token = process.env.PARTICLE_TOKEN; const particle = { listDevices: () !=> { return new Promise((resolve, reject) !=> { particleAPI .listDevices({ auth: token }) .then(devices !=> resolve(devices)) .catch(err !=> reject(err)); }); }, deviceFunctions: deviceName !=> { return new Promise((resolve, reject) !=> { particleAPI .listDevices({ auth: token }) .then(devices !=> { const device = devices.body.filter(device !=> device.name !!=== deviceName)[0]; return device.id; .then(id !=> { return particleAPI.getDevice({ deviceId: id, auth: token }); }) .then(device !=> { resolve(device.body.functions); }).catch(err !=> reject(err)); }); }};

27. THREE TYPES OF IOT APPS 1 2 3 IOT WEB

    APPS IOT MOBILE APPS IOT CLOUD APPS

28. HOW MOBILE APPS ENABLE THE IOT VISUALIZATION AND CONTROL PORTABLE

    AND UBIQUITOUS 2 IOT MOBILE APPS

29. EXAMPLE: THE BLYNK APP

30. OPTIONS FOR BUILDING IOT MOBILE APPS 1 2 3 NATIVE

    APPS GENERIC CONTROLLER APP CROSS-PLATFORM

31. SDKS FOR MOBILE DEVELOPMENT myPhoton!.getVariable("temperature", completion: { (result:Any?, error:Error?) !->

    Void in if let _ = error { print("Failed reading temperature from device") } else { if let temp = result as? NSNumber { print("Room temp is \(temp.stringValue) degrees") } } }) List<ParticleDevice> devices = ParticleCloudSDK.getCloud().getDevices(); for (ParticleDevice device : devices) { if (device.getName().equals("myDevice")) { doSomethingWithMyDevice(device); break; } } ParticleDevice myDevice = null; List<ParticleDevice> devices = ParticleCloud.SharedCloud.GetDevicesAsync(); foreach (ParticleDevice device in devices) { if (device.Name().equals("myDeviceName")) myDevice = device; } [myPhoton getVariable:@"temperature" completion:^(id result, NSError *error) { if (!error) { NSNumber *temperatureReading = (NSNumber *)result; NSLog(@"Room temperature is %f degrees",temperatureReading.floatValue); } else { NSLog(@"Failed reading temperature from Photon"); } }];

32. THE NATIVESCRIPT PARTICLE PLUGIN listDevices(): void { this.devices.splice(0, this.devices.length); this.set(HelloWorldModel.SELECTED_DEVICE_KEY,

    undefined); this.particle.listDevices() .then(devices !=> { if (devices.length !!=== 0) { this.set(HelloWorldModel.MESSAGE_KEY, "No devices have been claimed in this account."); } else { this.set(HelloWorldModel.MESSAGE_KEY, "Select a device below:"); } this.devices.push(devices); }) .catch(error !=> this.set(HelloWorldModel.MESSAGE_KEY, error)); } onDeviceTap(args): void { this.set(HelloWorldModel.SELECTED_DEVICE_KEY, this.devices.getItem(args.index)); this.set(HelloWorldModel.MESSAGE_KEY, `Selected: ${this.selectedDevice.name}`); }
