How to increase relative humidity and temperature in a box ? Answered
I need to increase the relative humidity of a slightly ventilated box up to 60-90% and to set temperature to 20°c (the outside should always be colder than 20°c). The box is closed (only two holes for the fans) and its dimensions are 1000*600*300 mm³. I only need to know which "hardware" to use. They will be switched on and off by a relay which is controlled by a humidity/temp sensor.
Thanks for your answers :)
