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. Continue reading
