Thermo-Electric Coolers (TECs, TE coolers, or peltier modules) can generate both heating or cooling thermal power when applying an electric DC current at different directions. When the current flows in one direction, one of the TEC's plates is heated up while the other is cooled down. As the current reverses the direction, the TEC plates will reverse their thermal polarity accordingly.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
