New sensor technology leads to more efficient presence detection in sectors such as construction and real estate. They are small, inexpensive, battery-powered, and IoT-caged sensors that will connect into the IoT with upcoming 5G networks.

The Value of Thermopile Sensing

Most of today's presence detection sensors are built with pyroelectric sensors, which only sense changes in temperature. But the newest sensors can be used to measure absolute or relative temperature as well as to detect  heat flow movement and presence. Moreover, they do not consume any energy when not in use, so they have a long battery life.

They are equipped with a thermopile that converts thermal energy into electrical energy, manufactured using nanotechnology. The sensors themselves measure only 0.17 mm in thickness, almost entirely made of plastic, which makes them flexible and cost-effective.

The Uses of Thermopile Sensing

These sensors can be used for smoke and gas detection, movement detection, heat measurement, as well as control of heat-sensitive parts and plumbing. They can also potentially be used to activate biometric authentication systems, such as fingerprint scanning or facial and iris recognition, eliminating the need to leave the authentication systems in a constantly active status. 

Ultimately, new thermopile sensors save energy and increase safety when applied within the construction and property sectors.
