Tutorial: Create a connected sensor

This tutorial demonstrates how to build a simple sensor and publish its values online (on a web server) using an ESP32 module. We will build an Arduino sketch which will read the sensor values, connect to WiFi, connect to a website and publish the values on the website. The published values can then be used … Continue reading Tutorial: Create a connected sensor

Getting started with the ESP32 Wifi module

The ESP32 Wifi module can replace an Arduino, as it has similar properties. Just like the Arduino Nano it can be mounted on a breadboard. This allows building very compact prototype circuits: To get started, Sparkfun’s “ESP32 Thing Hookup Guide” is a good tutorial. I am not going to repeat that. If you want a … Continue reading Getting started with the ESP32 Wifi module
