It measures both moisture and air temperature.
Dht11 temperature and humidity sensor arduino code with led.
It s perfect for remote weather stations home environmental control systems and farm or garden monitoring systems.
In this tutorial i ll first go into a little background about humidity then i ll explain how the dht11 measures humidity.
The dht11 humidity and temperature sensor makes it really easy to add humidity and temperature data to your diy electronics projects.
In this tutorial we will learn how to use a dht dht11 version temperature and humidity sensor.
The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino.
Project showcase by rick findus.
In these tutorials we will measure temperature and humidity by using dht11 with arduino.
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.
On the display is printed temperature celsius and humidity with a dht11.
Code of dht11 interfacing with arduino code for dht11 temperature and humidity sensor.
Void setup serial begin 9600.
Display for dht11 temperature and humidity.
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.
It s accurate enough for most projects that need to keep track of humidity and temperature readings.
Temperature and humidity sensor with led lights.
Dht11 sensor used with lcd display and led lights arduino created by ralph nader on 1 10 19.
The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino.
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.
When it s raining the led lights up.
The dht11 is a digital sensor that lets you easily get relative humidity and temperature readings in your projects.
Grad celsius and fahrenheit possible.
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.
You need a rain sensor.
Again we will be using a library specifically designed for these sensors that will make our code short and easy to write.
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.
