The temperature web server is a simple, lightweight and easy to use HTTP server for displaying current temperature. This can be useful for monitoring temperatures from multiple locations or for displaying the current outside temperature to your users.
The temperature web server is written in Go. This means that you don’t need to install any third party software on your computer – just download the executable file and run it! If you’re unfamiliar with Go, don’t worry – it’s easy to learn and is strongly typed, meaning there’s less chance of making mistakes.
Temperature Web Server
This is a simple web server that measures and displays the temperature online. It is mainly targeted at the esp32 boards, but can also run on other Arduino boards. The main purpose of this project is to provide a simple example of how to create an asynchronous web server with the ESP8266 WiFi chip.
The server reads the temperature from a DHT11 sensor every second and sends it to the client. The client can request data by clicking on the refresh button in their browser. This causes them to get a new value for the temperature every second until they stop requesting it (i.e., click on refresh again).
The goal of this tutorial is to show you how to build a simple temperature monitoring system using the esp32, esp8266 and DHT11 sensor.
We will use the Arduino IDE and some libraries to create an HTTP server which will serve our temperature data.
The project consists of two parts:
A web server running on the ESP32 that displays the current temperature (from the DHT11), humidity (from the DHT11), and air pressure (from the BMP180) in a browser. The web server can be accessed from any device connected to your home network, such as your smartphone or laptop.
A control interface that allows you to change the temperature setpoint via a web page or mobile application.
The ESP8266 is a cheap Wi-Fi chip with full TCP/IP stack and microcontroller capability. It was originally designed by the Chinese company Espressif Systems for a low-cost, low-power IoT application. It can be programmed in C or assembly code. The ESP8266 can be used as an access point, client device, router or server [1].
The DHT11 sensor consists of a humidity sensor and a temperature sensor. This tutorial will show you how to make an Arduino web server that takes readings from the DHT11 sensor and sends them over the internet via WiFi.
The temperature sensor is a DHT22 sensor. It is a digital temperature and humidity sensor which uses 2.5V as the power supply. The ESP8266 has an I2C interface, so you can use it to read the data from the DHT22 sensor.
The DHT22 sensor has a data pin and a clock pin, so you have to connect them with the ESP8266 board. The data pin of the DHT22 is connected to GPIO0 (D0) of the ESP8266 board, while its clock pin is connected to GPIO2 (D1).
To make it easy for you to connect this module with your web server, we’ve created an example project for you. All you need to do is download our code and upload it on your board!
This example shows how to use DHT11 sensor with ESP8266. The DHT11 is a low-cost sensor for measuring temperature and humidity. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed) that you can read with Arduino.
The library used in this example is Adafruit’s very good DHT library. This is not the only library available, but it’s my favorite.
ESP8266 Temperature Sensor Web Server
This is a basic example of how to make an ESP8266 with a DHT22 temperature and humidity sensor send data to a web server.
The example code uses Arduino’s Async Web Server library. It works on any ESP8266 board.
The ESP8266 is a great little module, but it can be hard to use if you aren’t familiar with its quirks. One of the most common problems is getting it to work as a web server, especially from an Arduino environment.
In this tutorial we’ll show how to create an ESP8266 web server and how to use DHT22 sensor with the ESP8266. The code uses the Arduino as a bridge between the ESP8266 and your computer, so you won’t actually need any programming knowledge for this project (but it might help).
The example code below shows how to connect to a remote web server from the Arduino. The main purpose of this tutorial is to show how you can use an Arduino as a web server, but it also shows how to read an analog input from the Arduino and display the value on a webpage.\
The ESP8266 is a WiFi enabled microcontroller that has been getting very popular with hobbyists lately. It’s cheap ($4-7), has built-in WiFi, and is easy to use thanks to its integrated Arduino-compatible environment.
The following example is based on the Adafruit library for the ESP8266: https://github.com/adafruit/Adafruit_ESP8266_Arduino_Library
This is a simple web server example using the ESP8266, written in Arduino IDE. The ESP8266 is a programmable microcontroller that includes a full Wi-Fi stack and a variety of interfaces (including GPIO, PWM, I2C and ADC).
The project is based on the work of others:
1) https://github.com/esp8266/arduino – This is an Arduino library for ESP8266 WiFi chip. It provides an API for controlling all of its features.
2) https://github.com/4refr0nt/esp8266_async_web_server – An asynchronous HTTP server for ESP8266 with support for static files, built-in directory listing and multiple virtual hosts (with optional caching).
The temperature sensor is a DHT22. It is a digital temperature and humidity sensor. The sensor has a single wire interface, so you only need to connect one wire to your microcontroller.
The data of the sensor can be read over serial, so we will use the Arduino IDE and a simple NodeMCU firmware to read data from our sensor and display it on a webpage.
The ESP8266 is a cheap WiFi module that can be programmed with the Arduino IDE, which makes it very easy to integrate into your projects.
To make this project work we need:
An ESP8266 development board with NodeMCU firmware (I used an Adafruit Huzzah).
