Human detection

With the development of the Internet of Things, smart cities and smart homes are becoming more and more popular. For example, in the smart home scene, the night light is intelligently turned on at night, and change to away-home mode when going out. Another example is the "no-card power collection" in the hotel rooms. In long-term and short-term rental apartments, the management party needs to detect whether there are people in the room in real time, and whether there are safety hazards and other management demands. For the application of these scenarios, the prerequisite is to accurately detect whether there are people in the room. Human body detection technology has developed for a long time. Currently, there are human body detection sensor products of different qualities and principles on the market, and more than 95% of the market products belong to infrared pyroelectric technology.

1.Motion sensor lights

There are more use of motion sensor lights in home life and bring us great convenience. Winsen’s self developed PIR sensor is excellent for sensor lights indoor and outdoor. The sensor works based on pyroelectric infrared principle, detecting human body wave length going through light filter window which can pass other wave length interference. Adding different Fresnel lenses, the sensing distance can be adjusted from 2 to 10 meters according to different use demand.

3.Static human detection

The thermopile temperature sensor is the core component of the forehead and ear thermometers, which has the characteristics of good cost, long service life, fast response and high precision. With the development of technology, thermopile sensors are also used in kitchen range hood, extractor, exhaust, integrated stoves and smart air conditioners. The future market direction will promote its application in smart home appliances, consumer electronics (Bluetooth headsets, facial massages), and medical equipment.
