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...
DHT11 Sensor Library MQ-135 Sensor Library Adafruit GFX Library Adafruit SSD1306 Library Blynk ESP8266 Library After you add these to Arduino IDE library, the codes will be compiled automatically. However, change theWi-Fi SSID,Password, and theBlynk Authentication Tokento connect the ESP2866 circu...
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...
button-cell battery powers the RTC when not connected to the Arduino. The DS3231 also has an inbuilt temperature sensor. The DS3231 usesI2C communicationwith the two bidirectional lines: serial clock (SCL) and serial data (SDA).How to connect with Arduino for this connection diagram is ...
The analog pins allow the board to read signals from an analog sensor, like a light sensor and convert it into a digital value. Even though the primary function of the analog pins for most Arduino users is to read analog sensors, the analog pins also have all the functionality of general...
Seeed Studio XIAO SAMD21SAM (Fully Arduino Compatible) XIAO Expansion Board Grove – Wio-E5 (STM32WLE5JC), EU868/US915, LoRaWAN supported Grove – DHT11 Temperature & Humidity Sensor Hardware Connection Step 1:Connect the Wio-E5 module directly to the “UART” slot of the Expansion Board...
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!
And here's the "xbee Receiver" code, connect the second Arduino uno board with your computer and press the "Run on Arduino " button. Step 4: The Circuit The connections are pretty easy, see the above image with the breadboard circuit schematics. ...
As the wiring diagram shows, connect the anemometer to Maduino A9G for measuring wind speed, and connect the DHT11 to get the Tem/Hum value. 3.1.1 The Firmware for Maduino A9G 1. The firmware can be obtained from https://github.com/Makerfabs/Project-Wind-weather-station/tree/master/Exa...
