How does Signify SC1500 work?

The SC1500 Multi Sensor Bundle consists of a set of environment and occupancy sensors. Only occupancy data is integrated to the Workplace platform.

Motion Sensor

The detection area is sensed by a thermopile array. By software processing the information is processed to radiant temperature at surface level and people count data.

How is Signify Occupancy data reflected in Workplace Live Views?

Sensor Occupancy changes are communicated to Workplace upon value change, yet data streams can experience latency of up to 10 minutes:

• So as soon as occupancy is detected, a signal is send to the Workplace Platform, which will reflect in Workplace touchpoints' floorplans in near-real time: the location occupancy color goes from GREEN to RED almost instantly, but goes from RED to GREEN based on a fixed timer which cannot be shorter than 10 minutes.

• This means that human motion can only trigger the sensor to go from '0' to '1' , and not the other way around.

Once the sensor goes up (meaning “presence detected”), it can't change its state faster than 10 minutes, which is why the default decay on the red icon lasts 15 minutes. The decay is actually nothing more than a clock counting down .

In Workplace, a decay acts like a count down clock until the next refresh, regardless of the presence during that window.

In other words: The reason for using this decay is to indicate that the probability that the location is still occupied is lowering.

Decay Configuration options

Perhaps you would want to indicate in Workplace Live Occupancy View that if a Desk sensor has been triggered, the location is occupied for at least 2 more hours, so that colleagues and guests can go to lunch or drop by a meeting without having to fear that someone is clearing out their workplace? But at the same time you want to indicate that a meeting room has freed up as quickly as possible, so that it turns green (“available”/”not occupied”) and people can recognize this at a glance?

The Workplace back-end Studio configuration options have you covered: per room category, both the icon and the decay timer can be modified.

How does this reflect in Workplace Dashboards?

Even if you want to show your colleagues in Workplace Live Occupancy View that a desk is “occupied” while you’re actually jumping from meeting to meeting in other rooms, the data will show that the desk was only really occupied for some brief moments. Per default, data aggregation happens per 15 minutes.
