Abstract
In the last period, Internet of Things (IoT) is experiencing an increasing development, and the tendency of hosting applications and especially data, in cloud computing systems is growing. Currently, most of the Building Management System (BMS) analyse directly data or transfer it to the cloud.In this context, the proposed solution aims to read indoor thermal climate data from cloud computing platform and based on them operate a hydraulic motor. The input data could be generated by an in-house sensor monitoring solution or by a foreign BMS system that transmits open source data to cloud.In this study some conditions are imposed to the input data and as a result, control current is generated and transmitted in order to command proportional electro-hydraulic valve that drive a hydraulic motor. The electro-hydraulic valve is controlled with the help of an amplifier, by a data acquisition board (DAQ) that runs LabView application. With the help of the developed software, the motor speed and the direction of rotation can be controlled.In last years, the number of requests for architectures projects with moveable elements has increased because they multiply the possible use of the buildings. With the information generated by the sensors that measure the indoor climate parameters, the hydraulic motor could be used in such a construction. Examples of atypical buildings with special functionalities that the architects would propose and that needs high torque actuation are presented in this paper.

Summary
Internet of Things (IoT), considered by many to be one of the most important technologies of our day, has grown exponentially in recent years [1]. Computer control can improve motion performance of a hydraulic device in this respect [6]. In this context, the present paper aims to realize a solution for controlling a hydraulic motor using cloud data. The data will be read from an IoT platform, named ThingSpeak, and according to one of the read parameters, temperature, the control will be done. LabVIEW software will be used to read data from cloud and transform the read value into digital signal for DAQ. The DAQ will transform digital signal into analog one and will give it to the command unit of a hydraulic motor, see fig. The DAQ will transform digital signal into analog one and will give it to the command unit of a hydraulic motor, see fig. 1
