Projects with this part

• DHT22 Temperature and Humidity MeterBeginner20 minA project that measures humidity and temperature, in both Celsius and Fahrenheit, with a DHT22 sensor and writes them to the Serial Monitor every two seconds. It is more precise than the DHT11 and has a wider measuring range. Before uploading the code, install Adafruit's "DHT sensor library" in the Arduino IDE (and the "Adafruit Unified Sensor" library it asks for).Open project
