Tutorial: build a connected temperature sensor

Introduction to Arduino and programming . Practicals which use this tutorial have an introductory presentation (pdf). We will build a temperature sensor in this tutorial and connect it with an App. It uses an DHT11 temperature & humidity sensor and Bluetooth communication with a phone. We use a BLE-Nano here, but you can also use a regular Arduino … Continue reading Tutorial: build a connected temperature sensor

Use DHT11 temperature and humidity sensor with display

This tutorial uses the Arduino Nano, but you may also use an Arduino Uno. You might need the Arduino Nano pinout diagram or an other diagram for your particular model of Arduino. We are going to use the diagram below to build it. But if you are inexperienced each step is explained in detail. First, … Continue reading Use DHT11 temperature and humidity sensor with display

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. It’s main advantage is that it is faster, has more memory and has WiFi and Bluetooth on board. Just like the Arduino Nano it can be mounted on a breadboard. This allows building very compact prototype circuits: Make module ready for use … Continue reading Getting started with the ESP32 Wifi module
