Discover Leddar™ Technology
Leddar™ (Light-Emitting Diode Detection and Ranging) is a unique detection and ranging technology created by LeddarTech that performs time-of-flight measurement using pulses from infrared LEDs. Leddar™ continuously provides rapid and accurate detection and ranging, covering narrow and wide beams, in all cases without any moving parts. The diffused light beam, processed through innovative algorithms, allows for the detection of a wide range of objects under various environmental conditions.

The Leddar™One offers an efficient six-pin interface, including a RS-485. The module uses the MODBUS protocol, providing a robust, standard register-access interface for easy configuration and acquisition of measurement data. An interrupt signal is also provided to facilitate low-latency data acquisition.

Mechanical Integration
The module’s compact form factor and standard connector greatly facilitate integration in systems requiring detection and ranging capabilities.
Although not specific to level sensing, it is particularly well suited for NPT enclosures of 2” or more.
