ESP32 and SHT31 Temperature and Humidity Sensor Secure Web Server

In this blog post, I follow-up on the ESP32-IDF development and demonstrate how to incorporate an i2c device to measure the temperature and humidity. Specifically the SHT31. First, let’s do it plain-jane vanilla. We’ll incorporate the i2c device and simply display the measurements to the serial terminal through the uart. Next, we’ll make it more practical and send the data over the wifi network to a service that makes it convenient to visualize the time-series data.

Programming the ESP32 on your Mac!

Go out and buy yourself a cheap little ESP32 SoC and follow these basic instructions to setup your development environment on your Mac. If you want to do some advanced C-programming to control your ESP32, this is for you. If you’d rather use Arduino and play with simple sketches then this is not for you – google how to use Arduino and off you go!

What you will need

So, of course you’ll need an ESP32 SoC development board. I recommend the SparkFun Thing. Lots of other choices, but this blog post will address some of the specific configuration considerations that you’ll need to be aware of when you select this particular device.
