Development of Firefighter's Monitoring and Tracking Device with ESP-Mesh Protocol by STEM Education

Abstract

A firefighter's monitoring and tracking device with ESP-mesh protocol is a set of an equipment for firefighter operation. Due to high risks and sudden dangers during their operation, the researcher had an idea to invent a firefighter's monitoring and tracking device with ESP-mesh protocol by integrating with STEM education process. The development process followed the engineering design process (EDP) with the following objectives: 1) to develop a firefighter's monitoring and tracking device with ESP-mesh protocol integrated with EDP process, 2) to find the efficiency of firefighter's monitoring and tracking device with ESP-mesh protocol, and 3) to study users' satisfaction towards the firefighter's monitoring and tracking device with ESP-mesh protocol. The results showed that the receiving-transmitting distance within the mesh signal was stable at the distance between 0 and 80 meters. When testing the performance of the developed device under the test conditions at the temperatures below and above 60 °C, it was found that the location alert, the temperature alert, the notification light status, and the notification sound status reached the efficiency of high performance at 100 percent. Moreover, the users reported very high satisfaction towards the firefighter's monitoring and tracking device with ESP-mesh protocol. When considering on each aspect, it was found that the aspect with the highest satisfaction was on the investment (=4.90, 5.0.0.30) followed by the operation efficiency which was practical and easy to use (=4.80, S.D.=0.40). The overall satisfaction of all aspects was at the highest level ( =4.71, S.D.=0.46)
