Passive Infrared Sensor
The Kozee Passive Infrared Sensor (PIR Sensor) is a self-powered ceiling-mounted sensor that monitors the environment for person movement and measures ambient light level both via a dedicated illumination.
Under standard operation conditions the Kozee PIR sensor is self-supplied via its solar cell in conjunction with an internal energy store which enables the Kozee PIR sensor to operate 4 days in absolute darkness.
Key applications include lighting control based on presence and ambient light level as well as occupancy monitoring.
The Kozee PIR sensor reports motion detection and illumination measurements wirelessly using Bluetooth Low Energy (BLE) advertising and therefore does not require any wiring.
Additionally, as simple user interface consisting of one button, one switch and one LED allows for simple configuration without additional tools.
The Kozee PIR sensor reports regularly the measured light level and the status of the motion detection sensor. The motion sensor of the Kozee PIR sensor is permanently active so that initial motion will be reported immediately.
