-## Reducing power consumption of IoT nodes: a hands-on
 This project will be used in hands-on sessions to let attendees experience the development of low power IoT nodes.
-### More information about these sessions
-In this hands-on session the attendees will experience the development of a wireless sensor node. More
-specifically, how low-power operation can be achieved by clever utilization of the available resources.
-Such design choices include: selecting the right wireless technology, duty-cycled operation, hardware
-acceleration, etc.
-The participants will experiment with a custom LoRa-based sensor, built with a Semtec SX1272 Radio
-chip and an EFM32 Cortex M0 processor. The way operations are being performed on the node can be
-customized in the Silabs Simplicity Studio IDE. The effect of these changes on the energy consumption
-can be observed through the IDE’s built-in energy profiler.
-In the end, the lecturers will have shown that the design of true low-power wireless sensors requires a
-thoughtful design. Both software and hardware need to work seamlessly together within the boundaries
-of a specific application.
