RECORDING OF ENVIRONMENTAL PARAMETERS USING A WIRELESS SENSOR NETWORK

Abstract: The Military Institute of Aviation Medicine possesses a specialized research device—a thermobaric chamber—designed to simulate environmental conditions occurring during flight inside an aircraft, as well as in emergency situations such as damage to the aircraft’s external structure. The simulator enables the generation of conditions with reduced atmospheric pressure and a wide range of variable temperature and humidity levels. Research involving both humans and technical equipment is conducted in the thermobaric chamber. The chamber is equipped with a wired system for monitoring the environmental conditions inside it. However, due to the specific nature of some studies, it is necessary to use multiple additional temperature sensors placed in various locations within the tested object. Therefore, the use of sensors with wireless data transmission is the most advantageous. Simultaneous measurement using multiple such sensors requires the implementation of a measurement data acquisition system. The aim of this work was to develop and construct a functioning prototype of a system for recording environmental conditions using a wireless sensor network. The proposed solution met the required functional specifications. The system enabled the recording of humidity and temperature, as well as the archiving of measurement data.
