Temperature Monitoring Through Wireless Sensor Network Using an 802.15.4/802.11 Gateway

:The wireless sensor network (WSN) has a wide range of uses. It can be used, for example, as a powerful tool for gathering several kinds of environmental information. This type of monitoring fits in the concept of Internet of Things (IoT), which aims to optimize the real world processes by monitoring their variables. In this study, a WSN developed in the IEEE 802.15.4 standard was used with the objective of measuring the local temperature. The access to the data was available through a WLAN network in the IEEE 802.11 standard (also known as Wi-Fi), an already existing network or a solution's dedicated network were used. Quality tests of signal and maximum range of communication of the WSN were made, as well as the network's battery lifetime usage estimates. Finally, the study also shows the monitoring of the temperature of some environments.
