Dht11 Temperature And Humidity Sensor Arduino Code With Led

Grad celsius and fahrenheit possible.

Dht11 temperature and humidity sensor arduino code with led.

In this tutorial we will learn how to use a dht dht11 version temperature and humidity sensor. Arduino temperature humidity rain sensor. Complete guide for dht11 dht22 humidity and temperature sensor with arduino this article is a guide for the popular dht11 and dht22 temperature and humidity sensors with the arduino. Void setup serial begin 9600.

Learn how to use temperature and humidity sensor with arduino how to connect dht11 or dht22 temperature and humidity sensor to arduino how to program arduino step by step. Project showcase by rick findus. Dht11 sensor used with lcd display and led lights arduino created by ralph nader on 1 10 19. We ll explain how it works show some of its features and share an arduino project example that you can modify to use in your own projects.

In this tutorial i ll first go into a little background about humidity then i ll explain how the dht11 measures humidity. It s perfect for remote weather stations home environmental control systems and farm or garden monitoring systems. Code of dht11 interfacing with arduino code for dht11 temperature and humidity sensor. In this project we re going to use the dht11 humidity and temperature sensor to calculate the average temperature and humidity every hour.

The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino. In this instructable i have used the dht11 temperature humidity sensor arduino uno to display the current temperature humidity readings into a 16 x 2 lcd display alongside i have also created a 3 led setup which indicates 3 sets of temperature readings cold hot extreme. It measures both moisture and air temperature. On the display is printed temperature celsius and humidity with a dht11.

It s accurate enough for most projects that need to keep track of humidity and temperature readings. The dht11 humidity and temperature sensor makes it really easy to add humidity and temperature data to your diy electronics projects. Again we will be using a library specifically designed for these sensors that will make our code short and easy to write. The dht11 temperature and humidity sensor senses measures and regularly reports the relative humidity in the air.

You need a rain sensor. Include dht h including the library of dht11 temperature and humidity sensor define dhtpin 2 selecting the pin at which we have connected dht11 define dhttype dht11 selecting the type of dht sensors dht dht dhtpin dhttype. Here we also display those readings on an lcd display. When it s raining the led lights up.

Temperature and humidity sensor with led lights. Display for dht11 temperature and humidity. The dht11 is a digital sensor that lets you easily get relative humidity and temperature readings in your projects.
