DHT22 - Humidity & Temperature Sensor

grabcad

This little module measures humidity and temperature accurately, thanks to a calibrated integrated digital sensor that gives a highly reliable reading of moisture levels and air temperatures in environments like offices, gardens, homes and warehouses. For example, the user simply sets an address through an I2C/SPI interface after power-on and gets both measurements - they don't need anything more sophisticated. In contrast to the classic analog DHT22 devices available online today, our new DHT11 model offers even simpler usage because it works well with either digital I/O lines (pins). There is only one thing left - make sure the output cable is properly connected on your motherboard; everything else happens automatically in most microcontrollers and boards once set correctly according to your particular development board's datasheet documentation.
