The results of a questionnaire on energy, operations and data transmission in extreme conditions., aiming to identify needs of Research Infrastructures (RI) remote stations with respect to extreme conditions, clearly indicate that the main problem/need for RIs operating in extreme conditions is in relation to temperature to which instruments/sensors operate and data are collected. Internal humidity conditions are also environmental conditions of relevance for RIs that are operating in extreme environments. Based on these findings, work on task 3.2 reported in this deliverable concentrates on developing an electronic board and related firmware able to pilot selected technical solutions for regulating/controlling Temperature and Relative Humidity at which instruments operate in extreme environmental conditions.

Existing technologies to regulate T and RH have been extensively reviewed and the most suitable to support RIs operations/activities in remote and extreme environments have been selected. For them we developed a PCL-based control unit/tool, based on two electronic boards (we separated power operations from the more delicate signals/commands handling and generation as well as data acquisition) and dedicated firmware providing the intelligence to drive each of the three selected technologies to regulate/control the temperature at which instruments should operate. The system is able to control non only the target temperature but also as much as possible thermal gradients internal to the heated box.

To extensively test the efficiency of the developed hardware and software in real conditions (i) thermoregulated systems (proofs of concept) have been designed and then in large part realized, and (ii) a test plans has been prepared and in large part implemented. Results Analysis clearly demonstrate capability of our control unit and associated algorithms to control temperature in a very extended range of environmental conditions. Developed control unit, joint to recommendations and information provided in this deliverable should able ENVRI RIs to address in the right way issue related to operational temperature control in the largest part of cases.
