Projects with this part

• DHT11 Temperature and Humidity MeterBeginner20 minA starter project that measures the room's temperature and humidity with a DHT11 sensor and writes the values to the Arduino IDE's Serial Monitor once a second. Before uploading the code, install the DHTlib library in the Arduino IDE.Open project
• LCD ThermometerBeginner30 minA small device that shows temperature and humidity on a 16x2 LCD instead of the Serial Monitor, so it can sit on a desk without a computer. The DHT11 is read every two seconds; the top line of the screen shows the temperature and the bottom line the humidity. It teaches driving a screen over I2C with just two data wires, using two libraries together, and updating a line on the screen without clearing it. Install the "LiquidCrystal I2C" and "DHTlib" libraries from the Library Manager.Open project
