Real-Time Temperature and Humidity Monitoring using Arduino UNO and DHT11 Sensor - Python Language

Here is an example of a code for monitoring temperature and humidity using an Arduino UNO and a DHT11 sensor:

This code uses the DHT library to read data from the DHT11 sensor. The DHT11 sensor is connected to the Arduino UNO using the digital pin 2. The code reads the temperature and humidity data from the sensor and prints it to the serial monitor. The loop in the code allows the program to continuously read the data from the sensor, so the temperature and humidity can be monitored in real-time.

For this project, you will need the following electronic items:

1. An Arduino UNO
2. DHT11 Temperature and Humidity Sensor
3. Jumper wires

The DHT11 sensor is a low-cost, digital temperature and humidity sensor. It is easy to use, and it can be connected to the Arduino UNO using a few jumper wires. The sensor has three pins: VCC, GND, and DATA. The VCC pin needs to be connected to the 3.3V or 5V pin on the Arduino UNO, the GND pin needs to be connected to the GND pin on the Arduino UNO, and the DATA pin needs to be connected to the digital pin 2 on the Arduino UNO.

Here is a sample circuit diagram explanation for the setup:

In this circuit diagram, the DHT11 sensor is connected to the Arduino UNO using three jumper wires, the VCC pin is connected to the 3.3V pin, the GND pin is connected to the GND pin, and the DATA pin is connected to the digital pin 2.

Please note that this is just a sample code and circuit diagram, you may need to adjust the code and circuit to suit your specific requirements and hardware.

You will also need to install the DHT library for Arduino IDE to communicate with the sensor.

For electronic items that you can get on Amazon, here are some examples: I have provided the links, if you do not have already then you can buy it.

1. DHT11 Temperature and Humidity Sensor Module for Arduino
2. Arduino UNO R3
3. Jumper wires (male to female, male to male, female to female)
4. Power Supply

Please note that these are just examples, and there are many other options available on the market. It is important to check the compatibility and specifications of the components before buying them.

Once you have the circuit set up and the code uploaded, you can monitor the temperature and humidity by opening the serial monitor on the Arduino IDE. The values of temperature and humidity will be displayed on the serial monitor in real-time as the sensor is reading the data.

It is also possible to add more functionality and integration with other devices or services, based on the temperature and humidity reading.
