What is IoT? |
|
Then the video demonstration how a Python program on the IoT node can communicate through MQTT with the mosquitto server. The python program publishes dummy temperature data. |

The next video does not access MQTT but demonstrates how to switch an LED on a WeMos D1 prototype shield on and of. It also reads out a photo resistor and shows the change in resistance when the intensity impinging on it changes. |

|
Finally a video to demonstrate the full IoT system. You can switch the LED on the prototype board on or off with a Cayenne push button. This will change the light intensity on the photo resistor, which is shown on a gauge widget on Cayenne. If the light intensity falls below a predefined level a Cayenne trigger will switch built-in LED on the WeMos CPU on. If it goes back above that level, the built-in LED is automatically switched off again. |
