It should be possible to follow the instructions in this tutorial, but I strongly advice to familiarize yourself with the device and expansion board by yourself. **Step 1: (4 hours) Getting Started.** Installing your IDE of choice and connecting to the LoPy4. Note: In order to not duplicate too much information, there are some steps where I refer to the Pycom and other websites instead of repeating the information here. This tutorial will guide you to get started with connecting sensors to a LoPy4 device running MicroPython and expose the sensor data using MQTT. I measure temperature, air pressure, air humidity and soil humidity. In order to learn about connectivity with sensors I chose three different types: one digital, one using the I2C bus and one analogue. Therefore I chose to focus on local installations in my home network on a Raspberry Pi, rather than working in a cloud environment. I also wanted to explore MQTT brokers and how to share and visualize the sensor data. I chose this project to explore different alternatives and solutions related to middleware rather than fulfilling one specific practical use case.įirst of all, and most important, I wanted to learn about IoT and especially MicroPython devices and how they interact with sensors to collect data and how that data is shared. # Exploring MicroPython, MQTT and TIG Stack
