Part 2 of this series continues with answering common questions about how sensors work in IoT system development. What are smart sensors? Basic sensors can detect changes in their environments and convert measured data into a digital format for the external microcontroller to process. The “smart” is in the microcontroller. Combining the microcontrollers in a […]
