In this quite long video tutorial we go through the process of downloading and installing support for the DHT11 humidity/moisture and temperature sensor. We then make a sketch which enables us to control a dehumidifier and a heater to make sure that a washing room wont get too cold and too humid. We then build a circuit around this, and in the end also see the finished "product". This circuit will give you full control of a dehumidifer and heater which usually cant be adjusted to an exact temperature or humidity or moisture level (usually only set by using a dial).
