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...
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...

To create a 3 pin setup (GND, 5V and SIG) you have to connect both the trigger pin and the echo pin to the same digital pin on the Arduino. In the code, the only thing you have to change is line 6-7 and define the same pin for both the trigPin and the echoPin. For example ...
If you are interesting to make data recorder or data Logger of a sensors and to record its data in a file. here are the following links: 1-Temperature and light intensity data logging https://youtu.be/gd-a8Y5GF3A 2-DHT11 data recorder with Arduino & micro SD Card ...
If you’re interested, we have also go through the steps to handling Arduino’s serial reading and writing too, this in a separate tutorial. Raspberry Pi Temperature Sensor using the DS18B20 Raspberry Pi Motion Sensor using a PIR Sensor Build your own Raspberry Pi Twitch Bot Raspberry Pi Quiz...
Try downloading the Codebenderpluginand clicking on the "Run on Arduino" button to program your Arduino board with this sketch. And that's it, you've programmed your Arduino uno board with this sketch! And here's the "xbee Receiver" code, connect the second Arduino uno board with your com...
This article is an introduction to the MQTT protocol. MQTT stands for Message Queuing Telemetry Transport, a simple messaging protocol suitable for communication between IoT devices.
Log in and navigate to “Settings.” There, look for “View AIO keys” (the yellow box) and click on it. You will see your token, which you can copy and paste in Arduino sketches. Note:Keep that key secret because it allows you to connect to your dashboards!
Connect the Vcc and ground pin of the DHT11 sensor to the 5V and ground of the Arduino nano. Connect the output pin of the DHT11 sensor to the Pin2 and the IN pin of the relay module to the Pin3 of the Arduino. Power up the relay module through Arduino and connect the positive...
