The BrightBooking platform supports specific hardware for detection of people at a desk or in a room.
The currently supported sensoring work are battery powered occupancy sensors, which communicate over RF (868 MHz fo EU/Middle East, 915 MHz for the USA). Receiver units consist of an RF antenna, connected to an processing unit, and are used to receive the data and send it to the platform for analysis.
The sensors are powered by 3 standard AAA batteries, battery life will be 3 years, but keep in mind you need to use high quality batteries (lithium).
Desk occupancy sensor
The Desk Occupancy sensor is a sensor which measures the occupancy of a workplace position (e.g. a desk), through movement and thermal measurement. In an office environment this sensor would be placed under the desk, at a team table, reception desk, etc. Any location occupied by a person.
The combined movement and thermal measurement, gives the best possible detection.
It is the combined measurement of all these positions that provide valuable insights into how your space is used. Because the sensor is continually monitoring the occupation the data provides fact-based proof of occupancy over long periods of time supporting changes within the workplace by identifying those occupants with high levels of mobility.
Installation and positioning
The sensor is positioned under the desk at approximately 400mm from the front edge, with a measurement distance of up to 800mm from the sensor at an angle of 60° (fig. 1). In some cases, the desk has a metal support bar running down the middle of the desk so the sensor location needs to be in front of the bar (fig. 2).
Room PIR sensor
The PIR room detection sensor senses the movement of a person within a space and transmits the measurement of movement / the lack of movement. This way the sensor provides confirmation that the space is in use.
The PIR sensor has an optimal range of 2.5m with a coverage area of 7.5m by 6m at that distance (Fig 1). If a PIR sensor is placed flat on a standard office ceiling of 2.5m and a standard conference table is at a height of 0.73m the detection area at that level would be approximately 5.2m by 4.2m (Fig 2).
For ideal range and measurement the PIR sensor is placed at an angle towards the location where people use the room.
RF iLan Receiver
The RF Receiver is a combination of an RF Antenna, connected to an box processing unit. The processing unit connects to the internal network via Ethernet or WiFi, and processes the data to the platform.
The sensors / receiver have a range of about 40 meters indoors, in an open space environment.
