Very basic easy to use humidity controller with programability. These units are extremely helpful with the use of a fogger/humidifier and can also be used to dehumidify with fans etc.
These units have many applications beside reptile husbandry and are great for other applications where humidity control is required, mushrooms, germination, cigar cabinets etc.
The wiring is very basic with two wire with power in and two wires out to the device.
