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>#...
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. ...
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...
So, I'm using Arduino IDE with ESP to get Temperature and humidity with a DHT11 sensor (it is not the best, I know), compiling with the verbose enabled (just for debugging), and notice that whenever upload the sketch, I see some really good information that I'd love to use to prin...
DHT11 sensor has four pins-VCC, GND, Data Pin, and a not connected pin. Apull-up resistorof5kto10kohms is provided for communication betweensensorandmicro-controller. It’s fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can ...
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 ...
How to Use XBee Modules As Transmitter & Receiver - Arduino Tutorial : In this tutorial we will use two xBee (series 1) modules with the Arduino uno board. We will configure them to act as a receiver and transmitter to control the brightness of an LED wi
