Before you can use the DHT11 on the Arduino, you’ll need to install theDHTLib library. It has all the functions needed to get the humidity and temperature readings from the sensor. It’s easy to install, just download the DHTLib.zip file below and open up the Arduino IDE. Then go ...
The HC-SR04 is an inexpensive, easy to use ultrasonic distance sensor, with a range of 2cm to 400 cm. It is commonly used in obstacle avoiding robots and automation projects. In this tutorial, you will learn how the sensor works and how to use it with Arduino. I have included 5 exampl...
We have another tutorial on the DHT11 for theArduinothat goes into detail on relative humidity and how the DHT11 measures it. So instead of repeating all of that here, check outHow to Set Up the DHT11 Humidity Sensor on an Arduino, then come back for the specifics on setting it up o...
The code start by including the library for the DHT11 sensor and theLowPowerlibrary. For downloading theLow Power libraryfollow the link. Then we have defined the Arduino pin number to which the data pin of the DHT11 is connected and created a DHT object. #include <dht.h>#...
In this example, we will be using a DHT11 sensor Arduino Library. When you hover with your mouse over a library, you will see an Install button. Some of the libraries will have a version to choose from. By default, the newest version is chosen, but you can choose the one you want ...

Custom commands can be used for Arduino libraries as well! I wrote a custom command for the DHT11 humidity and temperature sensor using an existing Arduino library that reads information from the sensor each time the custom command is called. Try using custom commands for anything that can’t ...
Introduction: How to Make RGB Lighting Clock🌈 Neon Color Changing Wall Clock Using Ws2812 LEDs, DS3231, DHT11 and Arduino UNO 1 Step 1: Hi guys, today this project we using Arduino UNO, and get the real time via DS3231 clock module, get temperature via DHT11 sensor. And then, let...
I am trying to finish this project as my thesis but after a month trying different ways to solve it, I really don’t know what else to do now. I am building my app with App inventor 2 and with my arduino. I have a gas sensor which via bluetooth sends the numbers to the app and...
13: GPS Sensor GPS (Global Positioning System) sensors use satellite signals to output the user’s current location and velocity. Arduino boards can be paired with GPS modules to determine their own geographical coordinates. For example,the NEO-6M GPS Module. ...
