Introduction

This experiment demonstrates how to interface the ESP8266 Wi-Fi module with a temperature sensor (like the DHT11 or DHT22) and display the temperature reading over the web.

Materials Required

• ESP8266 Wi-Fi Module
• Temperature Sensor (DHT11 or DHT22)
• Resistor (4.7kΩ for DHT11)
• Breadboard and jumper wires
• Arduino IDE

Circuit Diagram

The following diagram shows how to connect the temperature sensor to the ESP8266:

Steps for the Experiment

1. Connect the temperature sensor to the ESP8266 according to the circuit diagram.
2. Write a program to read the temperature from the sensor and send the data to a web page hosted on the ESP8266.
3. Upload the program to the ESP8266 and connect it to your Wi-Fi network.
4. Open the web page on your browser and view the temperature data.

Explanation

The ESP8266 communicates with the temperature sensor to read the current temperature and then displays it on a web page, which can be accessed from a browser.

Results and Observations

• The web page should display the current temperature reading from the sensor in real-time.
