Search for 'esp' and install 'esp32 by Espressif System' and then select the 'ESP32 Dev Module' as the default board. Open up the IDE, and go to Tools | Boards | Board Manager. I installed the Arduino IDE from here and installed a compiler for the ESP32 board. To get started, I made sure I could actually send code to the microcontroller. Color Clock Temperature HumidityYou can find the schema & code on project page, below is the link. The project code is available here if you want to take a look. Oh, and I already had a DHT11 Temperature and Humidity Sensor laying around so I've added that to the project too. The ESP32 is a powerful little processor, including WiFi. That got me thinking about IoT and so I bought some toys to see what I could pull together.įor this project, I picked up a Duinotech Soil Moisture Sensor and an ESP32 dev kit for under 50 bucks. I've got some roses that haven't been doing so well lately, and I've been thinking it would have been nice to know that they were not doing well before any real harm was done.
