INSTALLATION AND TESTING THE FUNCTIONING OF A DEVICE FOR MEASURING TEMPERATURE AND HUMIDITY

Abstract

The article presents the installation and calibration of temperature and humidity measuring devices for a study on the thermal performance of Typha-based insulation panels. Two types of sensors were tested: the DHT11 ST052 sensor and the PCE-HT 71N data logger.

The methodology involved placing sensors in identical test cells, one with Typha panels and another with polystyrene insulation, to record temperature and humidity variations. Comparative tests assessed the accuracy, consistency, and reliability of both devices.

Results showed that the DHT11 ST052 sensor, while functional, had limited measurement ranges and significant variability, especially in humidity readings. In contrast, the PCE-HT 71N logger demonstrated superior precision, consistency, and reliability across different conditions, supported by low standard deviations and overlapping data curves.

Consequently, the PCE-HT 71N was selected as the most suitable sensor for the study due to its wider measurement range, higher accuracy, internal memory, and autonomy. The DHT11 remains useful for preliminary or qualitative assessments but is less reliable for long-term scientific monitoring.

The study concludes that accurate and stable sensors are essential for evaluating insulation materials, with the PCE-HT 71N ensuring robust data collection for comparing thermal efficiency in building applications.
