In this tutorial we’re going to show you how to build a web server with the ESP32 that controls the shaft’s position of a servo motor using a slider. First, we’ll take a quick look on how to control a servo
Learn how to publish temperature and humidity readings from a DHT11 or DHT22 sensor via MQTT with the ESP8266 NodeMCU to any platform that supports MQTT or any MQTT client. As an example, we’ll publish sensor readings to Node-RED Dashboard and the ESP8266 will be programmed using Arduino...
In this tutorial, you’ve learned how to publish readings from a BME280 sensor to ThingSpeak using the ESP8266 and the arduino-thingspeak library. You can change the examples to send readings from any other sensors or data from any other source. We have tutorials for the most popular sensors...
Learn how to display temperature and humidity readings from a DHT11/DHT22 sensor in an SSD1306 OLED display using an ESP32 or an ESP8266 with Arduino IDE. The idea of using the OLED display with the ESP32 or ESP8266 is to ilustrate how you can create a physical user interface for your...
This tutorial shows how to use the DHT11 or DHT22 temperature and humidity sensors with the ESP32 and ESP8266 development boards using MicroPython firmware.
To get started, follow the next tutorials: Arduino Core: ESP8266 DHT11/DHT22 Temperature and Humidity Web Server with Arduino IDE MicroPython: MicroPython: ESP32/ESP8266 with DHT11/DHT22 Temperature and Humidity Sensor Get a DHT22 temperature and humidity sensor. ...
There’s nothing in the loop() function, because your ESP is constantly in deep sleep mode and wakes itself up. voidloop(){ // sleeping so wont get here } Other changes – different sensor and degrees Fahrenheit Note that If you’re using a different sensor than the DHT11, you can co...
Here’s one, you can use an ESP8266 (https://randomnerdtutorials.com/esp8266) and connect a DHT11 sensor to the ESP8266. The esp8266 then serves a web page that shows you the humidity and temperature in your browser: https://randomnerdtutorials.com/web-server-tutorial. Reply ...
