I'll just go ahead and rewrite this article for you. Termostato Wi-Fi con ESP8266 Hey guys, today I'm going to show you how to create a Wi-Fi thermostat using the super cool ESP8266 module. This project is perfect for all of you who want to take control of their heating system and save some money on your energy bills at the same time. First things first, we need to get our hands on an ESP8266 module. You can find these modules on eBay or Amazon for a very low price. Once you have it, plug it into your computer using a USB cable and upload the necessary firmware. Next up, we need to install some libraries in order to communicate with the thermostat. We'll be using the WiFi library and the DS18B20 library. The WiFi library will allow us to connect to our Wi-Fi network while the DS18B20 library will enable us to read the temperature from a digital thermometer. Now that we have all the necessary libraries installed, let's move on to the code. I'll be using the Arduino IDE for this project, but you can use any other platform you prefer. The first thing we need to do is define some variables in order to store our Wi-Fi credentials and the temperature readings from the thermometer. We'll also need a variable to keep track of the current temperature setting. Here's how you should define these variables: const char* ssid = "your_wifi_ssid"; const char* password = "your_wifi_password"; double temperaturaActual; int temperaturaSetpoint; Next, we need to connect our ESP8266 module to the Wi-Fi network. We'll be using a WiFiClient object to do this. WiFi.begin(ssid, password); While we wait for the module to connect to the network, let's initialize the DS18B20 library and start reading the temperature from the thermometer. OneWire ds( D2 ); byte addr[8]; while (!digitalRead(D3)) { delayMicroseconds(500); } ds.search(addr); Next, we need to calculate the temperature reading from the thermometer. We'll be using the following formula for this: temperaturaActual = (addr[0] + addr[1]) * 0.1; Now that we have our temperature reading, let's check if it's within a certain range. If it is, we'll send an HTTP request to our server with the current temperature setting. if (temperaturaActual > temperaturaSetpoint) { // Send HTTP request } Finally, let's move on to the main loop of our program. In this loop, we'll continuously read the temperature from the thermometer and check if it's within a certain range. If it is, we'll send an HTTP request to our server with the current temperature setting. void loop() { ds.search(addr); temperaturaActual = (addr[0] + addr[1]) * 0.1; if (temperaturaActual > temperaturaSetpoint) { // Send HTTP request } delay(10000); } That's it! With this code, you should be able to create a Wi-Fi thermostat that can control your heating system and save some money on your energy bills at the same time. Note: This project is just for educational purposes and should not be used in production without proper testing and validation.
