Mobile + Cloud + IoT - Case Study
8 likes2,098 views
The document outlines a case study on developing a mobile app for monitoring electricity usage using IoT technology. Two alternative solutions are discussed: manually entering readings from a meter or using an IoT device with a light sensor to capture LED blinking signals from a digital meter. The proposed architecture includes a mobile app, cloud data source, and IoT device for data collection and analysis.

Mobile + Cloud + IoT - Case Study

- 4. Another Case Study Free idea, for you to build :)
- 5. You want to create mobile app to monitor electricity usage
- 6. How do you achieve that?
- 7. Alternative #1 - Solution Manually enter the reading from electricity meter, regularly
- 8. Alternative #1 - Problem Are we living in a stone age? There should be a better solution :P
- 9. Another meter (digital version) Anything in this meter that represents usage? Readable not only by human, but also by machine
- 10. LED blinking represents usage 1000 pulse = 1 kWh 1 pulse = 1Wh where 1 pulse = period = seconds between adjacent LED on Wattage = 3600 second/period Turn out, there is…
- 11. If only we have a way to read the LED pulsing period
- 12. Create mobile app to capture the blinking Do simple image processing to determine that LED is ON or OFF Then determine the frequency of the ONs Alternative #2 - Solution
- 13. Still need to physically come to the meter, to capture the blinking Impossible to do online usage monitoring Alternative #2 - Problems
- 14. Cannot be solved solely by Mobile App
- 15. Architecture Mobile app Cloud Data Source ???? For further data analysis and remote monitoring, you may need Cloud Still, how we collect the data?
- 16. You need IoT
- 17. Architecture Mobile app Cloud IoT device is the data source IoT Sensor MCU Network MQTT MQTT
- 18. IoT Architecture WiFi ModuleLight sensor (Photosensitive Diode) MCU
- 19. Used to determine electricity meter’s LED is being ON or OFF Put it as close as possible to meter’s LED LED is ON —> lower ADC value from light sensor Light sensor
- 20. Demo
- 21. Demo Architecture iOS app MQTT Broker on Azure MQTT MQTT Espruino + Light Sensor
- 22. For simplicity of this demo, I use Espruino platform for MCU and development framework Espruino
- 23. For internet connectivity via WiFi, I use ESP8266. Connected to Espruino Pico via WiFi Shim Espruino + WiFi
- 24. Instead of purchasing nice looking Shim, I made my own! Ugly, I know :) Espruino + WiFi
- 25. Espruino + WiFi + Light sensor Setup AO of light sensor <—> A5 of Espruino VCC of light sensor <—> 3.3v of Espruino GND <—> GND
- 26. Show me da Code!
- 27. iOS App Espruino Web IDE
