Smart-home Sensor Analysis

Reliability in smart home products gets more and more important due to the increasing popularity. In order to assess this, various criteria such as energy efficiency and communication security are to be defined, against which you can evaluate the reliability.

Many devices are supplied nowadays from a battery, thus the energy efficiency of the reliability is of crucial importance. For this purpose, we designed the data logger for current and voltage, a self-sufficient, high-resolution and low-cost measuring system to determine the energy consumption of individual nodes in interaction with other participants in a real-world scenario. As well, we can identify incorrect programming at an early stage of development.

Furthermore, many devices especially in existing buildings communicate wirelessly with each other in SRD band (868 MHz). As a tool for the assessment of radio communication, a network sniffer for the sub-gigahertz range emerged in our laboratories, which records and analyze the communication.
