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 ...
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...
Below you can find a tutorial on how to use aDHT11temperature and humidity sensor to calibrate the speed of sound and get a more accurate distance reading with the HC-SR04. How the HC-SR04 works At the front of the HC-SR04 sensor, you can find two silver cylinders (ultrasonic transducer...
In the above setup to demonstrateArduino Deep sleep modes, the Arduino is plugged into the USB ammeter. Then the USB ammeter is plugged into the USB port of the laptop. Data pin of the DHT11 sensor is attached to the D2 pin of the Arduino. Code Explanation The complete co...
The second dropdown menu is to filter out the topic of the library, like communication, device control, display, sensors, etc. In the search bar, you can type a search term such as a name, and you’ll get filtered results. In this example, we will be using a DHT11 sensor Arduino ...
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...
In this Arduino Tutorial we will learn how to use the DHT11 or the DHT22 sensor for measuring temperature and humidity with the Arduino board. 19 Comments Arduino Touch Screen Tutorial | TFT LCD In this Arduino Tutorial we will learn how to use TFT LCD Touch Screen with Arduino. 163 Comme...
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. ...
