Homematic IP presence sensor - registers the presence of people This presence sensor comes with a very sensitive motion sensor that responds to the smallest stimuli in a detection angle of a 105° within a radius of 3.5 m and to larger movements within a radius of 7 m. Automatic temperature compensation guarantees functionality even in rooms with floor heating or in the event of temperature fluctuations. The presence sensor can be activated by an additional twilight sensor. This makes it possible for the lighting to only be turned on by the presence of people when the ambient brightness falls below a defined level. In addition, the motion sensor can be used to control the alarm so that an unauthorised presence or tampering causes sirens to be triggered and push messages to be sent to your smartphone.
