New Sensor Technology Can Allow for Smarter Presence Detection
Small, inexpensive, battery-powered and IoT-caged sensors can be quickly connected with the help of 5G networks to bring about new and more efficient presence detection in, for example, the construction and real-estate sectors.
Apr 14, 2019—
A rapid technological development within the Internet of Things (IoT) means that more and more things in our everyday life can be connected. The connection is made with the help of a gateway or a hub, which can collect data from a large number of sensors, which it then forwards to the cloud via, for example, 5G.
The IoT and sensors will be each other's preconditions in a variety of technical solution areas in this connected world. One such area is smart homes and buildings. Here, the development is very fast, ranging from older sensors that control a relay that turns on and off a lightning system, to a whole new generation of sensors that can send data to just a single gateway, which in turn controls the lamp exactly the way you want.
Most sensor systems currently used for presence detection are built with pyroelectric sensors. But their properties are limited and they can only sense changes in temperature, making them less suitable for areas in which a user is expected to remain, for example, in a room or in front of a computer. A new type of sensor, on the other hand, could detect human presence by monitoring for heat radiation. In this way, it would be much better at detecting immobile people in a room or office space, or in front of a unit, such as a computer or a tablet.
