This Arduino project reads data from DHT11 and DHT22 sensors to measure temperature and humidity. The DHT11 sensor is a basic and affordable option, while the DHT22 sensor provides higher accuracy.

-The Temperature Sensor LM35 series are precision integrated-circuit temperature devices with an output voltage linearly proportional to the Centigrade temperature. -The LM35 device has an advantage ...

This method uses a heat pump to recycle the air used in drying, making it more energy efficient. This technology allows drying at lower temperatures and maintains the quality of the coffee beans. Heat ...
