In addition to controlling a humidifier it will calculate the Vapor Pressure Deficit which is useful for growing and maintaining healthy plants. See the documentation for details.

The documentation and Arduino sketch are contained in zipped folders.

This controller was designed to work with an inexpensive vaporizer like the Vicks Warm Steam Vaporizer.

The case has a location for adding a real time clock if desired, however I haven’t written any code for that.

* Update:
I am in the process of using this area for an ESP8266 (ESP-01) with adapter board to give it WiFi capability. The existing case design can be used if the separator is cut or broken out but I am enlarging this space to make room.

* I have the arduino code working to the point that using any web browser, the Air Temperature, Humidity, Leaf Temperature and V
