The example, shown further down, shows you how to use the DHT22 in your own Arduino sketches. DTH22 Pull Up Resistor . The sensor requires a pull up resistor that is specified in the datasheet 1k to 5k is recommended. The DHT2211 sensors use a serial communication interface, operating over long distances over 20m is claimed DHT11, 100m for

The DHT22 is a basic, low-cost digital temperature and humidity sensor. Try downloading the codebender plugin and clicking on the quotRun on Arduinoquot button to program your Arduino board with this sketch. Below you will also find codebender serial monitor, press connect button to start receiving data from sensor.

In this tutorial, you'll learn how to interface Arduino with DHT22 Sensor Humidity amp Temperature Sensor and use it for monitoring humidity and temperature applications. We'll discuss how to install and use the Arduino DHT22 Library and its functions.. Then, we'll create a couple of Arduino DHT22 code example projects to practice what we'll learn in this tutorial.

Learn how to program Arduino to read temperature and humidity from DHT22 sensor and module. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly get started with Arduino. Find this and other Arduino tutorials on ArduinoGetStarted.com.

Wiring - Connecting DHT11 and DHT22AM2302 to Arduino Uno. The wiring diagramsschematics below show you how to connect 3 or 4 pin temperature and humidity sensors to the Arduino Uno. A 10 k pull-up resistor is needed between the signal line and 5 V to make sure the signal level stays high by default see the datasheet for more info.

Wiring the DHT11 or DHT22 sensor to an Arduino. Now it's time to connect the sensor to your Arduino! Wiring the DHT11 or DHT22 sensor to an Arduino is simple and straightforward. These sensors have fairly long pins with 0.1 spacing between them, which makes them perfect for plugging directly into any standard breadboard.
