  • Mathias Damgaard md223im I have built an IoT device with an ESP32 microcontroller, a sensor for measuring temperature and humidity of my kitchen. I’ve also connected an LCD so I can read those values. The device also connects to the internet through Wi-Fi and sends the sensor data via MQTT protocol to Datacake. Datacake stores those values and lets you visualize them in different ways. Estimate project time would be probably be a day for a beginner and less than an hour for someone with experience. Objective As a complete beginner to the subject of IoT my objective was to learn the basics and explore different aspects of IoT, hardware and programming along the way. I knew I wanted to make something that I could have use for in my everyday life. Living in an old apartment building with less than stellar climate control where I regulate the airflow and temperature by opening and closing windows or the balcony door. Because of this temperature and humidity varies a lot. Therefore, I opted to make a weather station placed in my kitchen where the most dramatic shifts occur. That’s where my balcony door is and where my oven is sometimes running for hours a day since I like to cook and bake, preferably sourdough bread. Knowing the temperature where my dough ferments lets me easier predict when to proceed to the next stage of the bread baking, hopefully turning it into a great looking and tasting bread. Material Due to unexpected late cancellations of the materials I wanted, I ended up using the ESP32-WROVER which was included in a starter kit containing several things (172 items) including sensors, cables, a bread board, LEDs, LCD & resistors to name a few. It has comprehensive documentation on how to get started with their starter kit that can be found here.
