Human Presence Sensor

Human sensing also called human detection or human presence detection encompasses a range of technologies for detecting the presence of a human body in an area of space typically without the intentional participation of the detected person common applications include search and rescue surveillance and customer analytics for example people counters.

Human presence sensor.

Unlike typical pyroelectric human presence sensors that rely on motion detection the d6t thermal sensor is able to detect the presence of stationary humans by detecting body heat and can therefore be used to switch off unnecessary lighting air conditioning etc automatically when people are not present regardless of whether they move or not. The locations of the four ir sensors are defined as. As it has four ir sensors it can be used to detect the motion of the ir object and the relative position where the ir object moves. Each channel has a different field of view so not only can the ak9753 detect a human but it can also tell which direction the person is moving.

Each channel has a different field of view so not only can the ak9753 detect a human but it can also tell which direction the person is moving. The ak9753 human presence sensor is a qwiic enabled 4 channel nondispersive infrared sensor ndir. An integral analog to digital converter provides 16. Grove human presence sensor.

The grove human presence sensor can be used to detect the presence of the human body or any other infrared objects. Moreover it is composed of four quantum ir sensors and an integrated circuit ic for characteristic compensation so it can be used to detect the motion of the ir object and the relative position where the ir object moves. The sparkfun ak9753 human presence sensor breakout is a qwiic enabled 4 channel nondispersive infrared ndir sensor. The detection of human presence is becoming an important and even compelling requirement in a growing number of applications.

Moreover it is composed of four quantum ir sensors and an integrated circuit ic for characteristic compensation so it can be used to detect the motion of the ir object and the relative position where the ir object moves. The grove human presence sensor can be used to detect the presence of the human body or any other infrared objects. From computer peripherals personal electronics and domestic appliances to building access management healthcare and security systems today s applications must be able to ensure a seamless interactions of users with the systems and the services associated.
