In this project, you’ll learn how to build an asynchronous ESP32 web server with the DHT11 or DHT22 that displays temperature and humidity using Arduino IDE. The web server we’ll build updates the readings automatically without the need to refresh the web page. With this project you’ll learn: How to read temperature and humidity fromContinue reading “ESP32 DHT11/DHT22 Web Server – Temperature and Humidity using Arduino IDE”

In this tutorial you’re going to learn how to create a web server with the ESP32 to display readings from the BME280 sensor module. The BME280 sensor measures temperature, humidity, and pressure. So, you can easily build a mini and compact weather station and monitor the measurements using your ESP32 web server. That’s what we’reContinue reading “ESP32 Web Server with BME280 – Advanced Weather Station”

The ESP32 chip comes with 48 pins with multiple functions. Not all pins are exposed in all ESP32 development boards, and there are some pins that cannot be used. There are many questions on how to use the ESP32 GPIOs. What pins should you use? What pins should you avoid using in your projects? ThisContinue reading “ESP32 Pinout Reference: Which GPIO pins should you use?”

This tutorial shows how to put the ESP32 in deep sleep mode and wake it up with a timer after a predetermined amount of time. The ESP32 will be programmed with Arduino IDE.
