Technical requirements

As hardware, we need an ESP32 devkit, an OLED display, and a DHT11 sensor in this chapter. We will also need a mobile phone or any other device with Wi-Fi capability for when we test the examples. The examples in the chapter are located in the GitHub repository here: https://github.com/PacktPublishing/Internet-of-Things-with-ESP32/tree/main/ch6.

  • Bonjour browser for Windows: This is one of the options on Windows platforms for mDNS service discovery. The download page is here: https://hobbyistsoftware...
