Cheap and versatile humidity regulator for environmentally controlled experiments

Abstract

The control of environmental conditions is crucial in many experimental work across scientific domains. In this technical note, we present how to realize a cheap humidity regulator based on a PID controller driven by an Arduino microcontroller. We argue our choices on the components and we show that the presented designs can serve as a basis to the reader for the realization of humidity regulators with specific requirements and experimental constraints.
