“In my previous tutorial, MicroPython on ESP using Jupyter, we learned how to install and run MicroPython on an ESP device. Using Jupyter Notebook as our development environment, we also learned how to read from sensors (Temperature, Humidity, and Luminosity), We use several communication protocols and methods, Analog, Digital, 1-Wire and I2C, this last one to display our captured data on an OLED display.
Now, on this tutorial using an MQTT protocol, we will get all captured data, sending them to an IoT service, ThingSpeak.com and to a mobile App (Thingsview), where we can log and play with data.”
