OpenHumidistat
Lars Veldscholte mail
OpenHumidistat is a free and open-source humidistat for laboratory-scale humidity control that is affordable (=€400) and easy to build. The design is based around mixing a humid and dry air flow in varying proportions, using proportional solenoid valves and flow sensors to control flow rates. The mixed flow is led into a measurement chamber, which contains a humidity sensor to provide feedback to the controller, to achieve closed-loop humidity control.
