Wireless Sensor Networks
FEKT-MPA-SSYAcad. year: 2021/2022
The course focuses in practice and provides students with knowledge and experience in the field of wireless sensor networks and their applications. Students will learn to work with wireless sensor units equipped with microcontrollers and radio chips during the semester, using the IEEE 802.15.4 communication protocol, protocols using this standard, and the Bluetooth LE protocol. Part of the subject is the design and implementation of their own protocol, implementation of the wireless sensor network and its integration into the Internet of Things network. In the last part of the course the students will be acquainted with the possibilities of sensor unit design, power supply and sensing of physical quantities sensors.
Learning outcomes of the course unit
The students obtain knowledge about the wireless sensors, which are used in the home, building and transport automation- They will work with the Zigbee protocol and Atmel wireless nodes.
The subject knowledge on the Bachelor´s degree level is requested.
