ESP32 DHT11 Sensor HTTP Interface

This project is an Arduino-style ESP32 program that reads temperature and humidity values from a DHT11 sensor connected to GPIO 4. It is designed to be integrated with automation tools like Streamer.Bot by enabling HTTP requests to trigger or retrieve sensor data.

Features

• Reads temperature (°C) and humidity (%) from a DHT11 sensor.
• Outputs sensor readings to the serial console.
• Can be extended to provide HTTP endpoints for external applications such as Streamer.Bot.

Hardware Setup

• ESP32 development board.
• DHT11 temperature and humidity sensor.
• Connect the sensor data pin to GPIO 4 of the ESP32.
• Provide power and ground connections to the sensor as per the sensor specification.

Code Overview

• Uses the DHT library to interface with the sensor.
• Initializes the sensor on GPIO 4 with type DHT11.
• In the main loop, it reads humidity and temperature every 2 seconds, printing the values to the serial console.
• If the sensor data read fails, it outputs an error message.
