Measuring temperature, humidity, and light and displaying data on an LCD


In this section, I will teach you how to monitor temperature, humidity, and light detection on an LCD screen.

Hardware and software requirements

In this project, you will use an Arduino UNO board; but you can also use an Arduino MEGA, which also works perfectly.

For temperature reading,  we require a DHT11 sensor, a resistor of 4.7k, a photoresistor (light sensor), and a 10k resistor.

It also requires a 16 x 2 LCD screen, where you performed the tests; I used an I2C communication module for the screen interfaced with Arduino card. I recommend using this communication since only two pins of Arduino are required for sending data:

Finally, it requires a breadboard and male-male and female-male cables for connections.

Here is the list of components for the project:

  • Arduino UNO

  • Temperature and humidity sensor DHT11

  • LCD Screen 16 x 2

  • Module I2C for LCD

  • A breadboard

  • Cables

We connect the different components:
