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...
In this tutorial, I’ll first go into a little background about humidity, then I’ll explain how the DHT11 measures humidity. After that, I’ll show you how to connect the DHT11 to anArduinoand give you some example code so you can use the DHT11 in your own projects. BONUS: I ma...
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>#...
This will help you understand how App Inventor works and how it can interact with your arduino via bluetooth.
DHT11 Temperature and Humidity Sensor Raspberry Pi 16X2 LCD Display 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...
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 ...
