Leddar Sensor Technology: Detection for Smart Homes and Buildings

Advanced presence detection for smart appliances, security, occupancy sensing and robot appliances

Many households and office buildings are already equipped with smart sensors, collecting and exchanging all kinds of data destined to make our lives easier, more comfortable and more productive. Made available remotely through our personal computers and smartphones, the information captured by sensing devices enables systems such as smart heating and lighting, smart appliances, perimeter security or touchless controls, to only name a few.


Leddar technology’s advanced capabilities for presence detection, occupancy sensing, and gesture recognition provide the most attractive cost/performance ratio to integrators and OEMs. Developers can benefit from complete Leddar sensor modules customized to their requirements, or leverage the LeddarCore ICs to develop their own optical sensors for high-volume applications.


Leddar’s unique added value for Homes and Buildings


  • Detects all types of objects (people, animal, vehicles)
  • Wide area coverage
  • Consistent performance both indoors and outdoors
  • Low maintenance, high durability, and no calibration
  • Small, flexible form factor adapted to various designs
  • Low power consumption
  • Unbeatable cost/performance ratio

Leddar has gotten the attention of many integrators and OEMs in sectors such as consumer electronics, healthcare, smart appliances or security. In addition to hassle-free household management and energy conservation enabled by Leddar-powered sensing systems, advanced healthcare facilities can rely on the same technology to automatically monitor the number of available beds, or optimize sanitation with hands-free, gesture recognition controls for medical equipment.
