Design of a low-cost wireless data logger for monitoring the occupant's thermal perception

Conception d'un enregistreur de données sans fil à faible coût pour surveiller la perception thermique de l'occupant


Achieving thermal comfort for the building occupant often means increasing energy consumption. This work aims to develop an affordable, reliable, easy-to-use data logger to track occupants' thermal perception. It would allow the development of new approaches to achieving comfort by energy sobriety. This article presents the fabrication of a data logger device that allows a microcontroller-based system to measure an individual's physiological and physical parameters. The overall device is tested by comparing each sensor's mean output to assure that the physical measures have minor discrepancies. Also, the comparison was made to ensure that the two ways of data saving were reliable. The results indicated that the data logger showed no issues. The thermocouples had a reading difference of 0.05°C and constantly sent data. The oximeter needs to be closest to the wrist to return stable reading. The spectral decomposition sensors returned the same value but required to be placed perpendicular to the light source. Data were well transmitted to an online database and were well registered on the SD card. This is consistent with discoveries already made on those sensors. For the preliminary test, the measure confirms the efficiency of the design as it matches expectations and admits relatively low deviation for all units. Our finding showed that it is possible to secure the input in both ways: online and offline solutions. Also, it allows a more accessible protocol that uses more than two data loggers for online data records through Google API. Identifying individual parameters and not solely global parameters will permit further development toward fulfilling optimal thermal comfort. Despite the work done, design amelioration is needed to optimize the portability of the devices.
