Summary
Reads temperature and humidity data from the DHT12 digital sensor using the I²C interface.
Description
The **Humidity and Thermometer DHT12** component measures ambient temperature and relative humidity. It communicates over the I²C bus and provides precise digital sensing. The temperature can be reported in Celsius or Fahrenheit based on the **In Fahrenheit** property. A read cycle is triggered through the **Clock** pin, and results are available as analog outputs for temperature and humidity.
