TempSense - DHT11 Temperature and Humidity Sensor with ESP8266

TempSense is a simple Arduino project designed to read temperature and humidity data from a DHT11 sensor using an ESP8266 microcontroller. The project includes a single .ino file, tempsense.ino, which contains the code to initialize the sensor, read data, and print it to the Serial Monitor.

Project Files

• tempsense.ino: The main Arduino sketch for reading and displaying temperature and humidity data from the DHT11 sensor.

Prerequisites

Before running the project, ensure you have the following:

1. Arduino IDE: Install the Arduino IDE if you haven't already.

2. ESP8266 Board Support: Add ESP8266 board support to the Arduino IDE. You can do this by going to File > Preferences and adding the following URL to the Additional Boards Manager URLs field: Then, go to Tools > Board > Boards Manager, search for ESP8266 and install it.

3. Required Libraries:

• Adafruit Sensor Library: Install it via the Library Manager in the Arduino IDE (Sketch > Include Library > Manage Libraries), or download it from Adafruit's GitHub.
• DHT Sensor Library: Install it from the Library Manager or download it from Adafruit's GitHub.

Hardware Setup

1. ESP8266 Microcontroller: Use any ESP8266-based board such as the NodeMCU or Wemos D1 Mini.
2. DHT11 Sensor: Connect the sensor to the ESP8266 as follows:

• VCC to 3.3V (or 5V if your board supports it)
• GND to GND
• DATA to D4 (GPIO2 on many boards)

Uploading the Code

1. Open the tempsense.ino file in the Arduino IDE.
2. Select your ESP8266 board and port from the Tools menu.
3. Click the Upload button to compile and upload the code to your ESP8266.

Usage

1. Open the Serial Monitor from the Arduino IDE (Tools > Serial Monitor).
2. Set the baud rate to 115200.
3. After uploading, you should see temperature and humidity readings printed to the Serial Monitor every 2 seconds.

Code Overview

• Setup Function: Initializes serial communication and the DHT sensor.
• Loop Function: Reads the temperature and humidity from the DHT sensor, checks for errors, and prints the data to the Serial Monitor.

Troubleshooting

• No Data Displayed: Ensure the DHT sensor is properly connected and powered. Check the connections and ensure the correct GPIO pin is used.
• Error Messages: Verify that all required libraries are installed and up-to-date.
