Smart Sensors & Drivers
Many Smart Buildings use motion and light sensors to reduce energy consumption of the buildings lighting. Understanding the pitfalls in design and installation leads to lower installation costs and lower energy consumption.
The introduction of a sensor into every luminaire can have a positive effect on the total cost of installation and help reduce the buildings energy consumption.
Common Motion Sensor Issues
Achieving accurate detection
The placement of motion sensors in room is important, however due to cost (limiting the number of sensors used), installation (the cost of installing more than one sensor) or placement of the sensors, the way the sensors operate may be undesirable.
Installation too close to a doorway can trigger a false detection as people walk past. This results in unoccupied rooms being turned on, effectively wasting power. Additionally, the lights will remain on until the idle time has expired because of the false trigger.
In some cases, obstructions on the ceiling grid caused by air-conditioning vents, smoke detectors, speakers or other lighting, means the placement of the sensor is not ideal. This can lead to an installation where the occupant is detected well after they have entered the room.
Common Light Sensor Issues
Modern buildings utilise daylight harvesting to save energy, using light level sensors to detect the lighting level and dynamically reduce the artificially lighting levels to maintain a desired lux level. The effectiveness of daylight harvesting depends on the arrangement and setup of the light level sensors.
The placement of the light level sensors and the control of the lighting are often met with cost issues. To save costs installers use a minimal number of light level sensors, and control groups, leading to a poor outcome, as changes to the environment close to the sensor can affect light fittings placed further down the row in a room.
If an occupant closes a blind next to the sensor, the lighting further down the building has its brightness increased, reducing the energy saving benefits. Even more problematic is when an occupant seated away from the sensor closes their blind, the sensor does not detect any change leaving the light levels too low in some areas.
The light level sensors position is quite often dictated by where the motion sensor is installed, close to doors and workstations, as they normally are contained in the same product. The result is that the sensors are often installed in the centre of an area and not directly under the lights needing control.
The Solution – One Sensor per Fitting
As the lighting is installed in a uniform grid arrangement the placement of the sensors is reasonably guaranteed and would typically be located above workspaces. Where previously an employee siting in a corner or a person behind furniture, large monitors and plants would not have been detected, a sensor per fitting arrangement helps to ensure movement detection at all workspaces.
One light level sensor on every luminaire is an ideal solution, as all sensors must be satisfied before the light levels are reduced. The light levels do not anymore drop below the desired minimum. Looking for energy savings? The fitting based controls ensures optimal light levels without over lighting other areas.
Light level sensor in every luminaire by using non DALi-2 control can be problematic due to bandwidth constraints of many control systems.
Zencontrol Smart Driver
The driver for the connected luminaire is solving all these issues: built on IEC62386 V2 and smart technologies, zencontrol has perfected the “sensor per-fitting” concept. This driver is designed to make the most out of latest technologies and is offering a lower overall cost of installation / commissioning fro an attractive very item price .
Human Centric Lighting (HCL) or Circadian Lighting is devoted to enhancing human performance, comfort, health and well being. It’s a radical paradigm shift, based on the ambition, that artificial light shall serve humans at any moment.
Human Centric Light considers the three functions of light:
Functional lighting prevents user discomfort while increasing eye comfort and facilitates users activities such as concentration and creativity
Biological lighting is sometimes referred to as circadian light and is designated to support the sleep-wake cycle of people
Emotional Lighting is of creating an environment, which people see as comfortable and/or safe, giving the human a representation of the time of the day and good feeling
Colour change, multi-channel tuneable with colour
Zencontrol provides the ability to add full colour tuning to your building, not just tuneable white but tuneable colour
Colour change, multi-channel tuneable with colour
With zencontrol you have the ability to add full colour tuning to your building, not just tuneable white but tuneable colour
Easily create a circadian prescription to change colour and intensity during the day or night. zencontrol supports up to seven different intensity and colour changes throughout a day.
Additional techniques for a good human centric lighting design
Avoid Dark Rooms
Don’t allow users to walk into dark rooms- it can make occupants feel unsafe.
Well positioned sensors and standby lighting levels can help avoiding it
User comfort is improved when walking into areas where lights arent instantly turn on or off.
The use of DALI-2 drivers and control can help to control the lighting reaction.
Having unlit adjacent work areas can reduce the feeling of safety.
Use functions like corridor hold or illuminate adjacent areas to a minimum levels to increase the human wellbeing.
Software & Cloud
Cloud based lighting management brings an unprecedented level of functionality and control to your building and installations and allows you to remotely supervise and manage all your installations.
Zencontrol Cloud is an enhancement to standard lighting control systems. While all zencontrol buildings can operate without a cloud connection, adding cloud control provides a set unprecedented beneftis:
No longer locked in or limited by a static control systems. Zencontrol Cloud allows to add/remove functions at any time: add power monitoring, plan view, heat map or many other features as required
Manage multiple sites over one, centralized surface from wherever you are.
It allows facilities manager or site engineers to visualise, manage, adjust and deploy solutions from a centralized platform
Smart data technology allows simultaneous multi-user access, right down to the single light fitting
Commissioning and operational management is becoming much quicker, safer and error free
Setup and commission any site from the comfort of your office.
Change in real time how your building operates, or just add “earth hour”
Dramatically decrease building commissioning time by up to 100x with zencontrol Grid view. Quickly change device settings on thousands of devices in seconds.
Cut and paste settings across floors, buildings or sites. It has never been quicker or easier.
View your installation in an easy to understand plan view. See the location of lighting, switches and sensors. Plan view allows users to see the position of faults and the current state of the lighting.
Quickly and easily change room settings or light levels.
View occupancy maps, energy consumption, people movement profiles or even lux maps to better understand the usage of your building.

Get secure access to your site and data over the cloud API, allowing the seamless integration with your BMS
The zencontrol cloud protects your site data against loss of data for emergency test records and logs / malicious changes by rogue employees / loss or theft with automatic backups / crypto-lockers and ransomware / PC failure
zencontrol takes security seriously and sets an unprecedented standard in lighting control by using standards like TLS 1.2, SHA-2 and AES256-GCM over TCP/IP. The respective security documentation is available on request.
fast and reliabld data access is critical for proper building management. The zencontrol packet handlers ensures handshaking and closed-loop acknowledgements, ensuring all lights are controlled at any time and without compromise.
The World isn’t an Island and the seemless integration of newly build systems is vital to ensure the value for the Client.
