How to serve a web dashboard from the ESP32 with the device working as Soft AP. We will be using the ESP-DASH library and the Arduino core.
ESP32: Real-time web dashboard
How to use the ESP-DASH library to implement a web-based dashboard that will be updated in real time with sensor measurements (temperature and humidity). Under the hood, the update mechanism will be based in websockets. We will be using the ESP32 and program it with the Arduino core.
ESP32 Espruino DHT22: Getting temperature and humidity
In this tutorial we will check how to get temperature and humidity measurements from a DHT22 sensor using Espruino, running on the ESP32. The tests were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board. Introduction In this tutorial we will check how to get temperature and humidity measurements from a DHT22 sensor using Espruino, …
