Sensors

Our multi-sensor IoT system can be quickly installed to monitor live indoor occupancy levels and environmental conditions

It is a fully customisable system – which can be extended with 10s-100s of IoT sensors without additional cabling or new IOs.

SAHARA – Indoor air quality sensor

More info

The Sahara sensor is fully kitted out to measure: 

  • Carbon Dioxide (CO2) levels with a dual-channel NDIR chip (which achieves the accuracy to WELL Standard)
  • Particulate Matter (PM2.5) 

With an additional option of measuring:

  • Volatile Organic Compounds (relative change only), or
  • Ambient light levels and colour

It can be powered via a micro-USB cable or internally via hidden cables, compatible with 5V USB adapters. 

BASE – Broad range occupancy level sensor

More info

The “Base” is our long-range, broad level occupancy sensor, which determines the percentage occupancy levels by measuring the number active WiFi devices on a floor area c.3,000 – 5,000 sqft wide.

It also acts as a gateway node for our other wireless IoT sensors, and forms the backbone of our system.

EXTRA: The Base integrates directly with your building infrastructure (e.g. your BMS), locally via industry standard protocols (BACnet/IP), to reduce energy consumption, lower carbon emissions and improve comfort & air quality.

HAL – Granular occupancy count

More info

Hal is a ceiling-mounted sensor counts number of people in a room. For a normal office ceiling of ~2.5m Hal’s range is 6m x 6m.

It uses infrared technology and edge machine learning to detect thermal signatures (related to people) that are present in its field of view.

It pin points the position of such thermal signatures, and as well as counting the number of people, it is able to determine their position.

It is battery powered and has an estimated battery life of 5 years.

X1 – Desk motion sensor

More info

The X1 sensor is designed to measure if a desk is occupied, not occupied, or how long since it was last occupied. It uses a passive infrared (PIR) sensor chip to detect the movement of heat.

It is battery powered and lasts up to 5 years.

It is designed to be easily stuck under a desk, but can also be placed in a small meeting room.

HOTH – Temperature and humidity sensor

More info

The Hoth sensor measures temperature and relative humidity. Multiple temperature sensors in one space can be used to create and monitor spatial heatmaps, and balance floor heating or cooling, especially where solar gain is high.

It is battery powered, lasts up to 5 years.

Recommended placement is at shoulder height, away from heating or cooling sources.

ALPINE – CO2 sensor

More info

The Alpine sensor is the smaller brother of the Sahara, and measure only CO2 levels (via a dual-channel NDIR chip)

It is powered via a USB C cable, and can be used with any 5V USB power supply / adapter, eg your laptop.

Live Data Platform

Data collected in your buildings can be monitored in real-time and on the go through our insight digital portal

Intuitive dashboards, with historic analytics, live floor-plans, heat-maps and timeline

Different levels of information for building managers and building end user

Email alerts and notification when environment quality levels drop below optimal benchmarks.

IoT sensors

Sensor Unit

The data starts with the sensor units selected by the customer, such as air quality or temperature sensors. These subsidiary sensors operate in a transmit-only mode to send data to the LightFi Base sensor. The base sensor operates as both a sensor gateway and our patented long range occupancy level sensor. 

The Base Sensor

It includes an internal firewall and only communicates data outward to our managed IoT cloud systems using authenticated and encrypted connections.

BMS Integration and Building Automation

The base sensors can also send data directly into building management systems (BMS) to, for example, control ventilation based on occupancy levels, provide healthy and comfortable working conditions while saving a lot of energy.

Technical info

Our secure architecture

Highly secure 

Data is stored securely in the cloud and approved users can authenticate using our managed user system to view data for their building(s) using our web platform. User access can be restricted on a per site/building/floor basis depending on customer needs.  Sensor device functionality is restricted throughout to ensure only minimal required hardware and services are used. The limited nature of the communication used means that it is possible for customers to implement highly secure locked down internal networks and firewalls to further enhance their own security.  

Protecting your information and privacy  

Sensor selection can be tailored to customer needs but even the most extensive sensor package installed in a building presents both lesser potential intrusion (no microphone, camera etc.) and smaller attack surface (stripped down connectivity, minimal software overhead and hardware capabilities) than a typical mobile phone carried by building occupants.  The sensor system is fully GDPR compliant, and LightFi does not collect personally identifying information from the sensors. A DPIA is carried out regularly and fully accessible to our clients.
