What lcj capteurs does

LCJ Capteurs is a French designer and manufacturer of solid-state ultrasonic wind sensors, founded in 1999 by M. Lamiraux and headquartered in Vertou, Loire-Atlantique. The company produces vane-anemometers and wind measurement instruments based on ultrasonic transit-time measurement, eliminating moving parts and enabling low-power operation suited to autonomous and mobile deployments. Over more than two decades, it has commercialized 19,000+ sensors worldwide across marine, meteorological, and industrial segments, operating from a single French site as a private SARL with €38,000 of share capital.

The product portfolio is organized into four families: the CV7 series as the marine flagship, the CV3F for commercial applications, SONIC-ANEMO for terrestrial and industrial use, and the forthcoming METEO-SONIC line targeting professional meteorology. Supporting software (StatMETEO, €134 ex-VAT) handles data processing and statistical validation. Devices support NMEA0183, NMEA2000, SDI-12, Modbus, and analog protocols, enabling native integration with major marine electronics brands — Furuno, Garmin, Raymarine, B&G, and Simrad — and with industrial monitoring systems. Manufacturing is performed in France, with OEM customization available for embedded applications.

Revenue is generated primarily through unit hardware sales (sensors priced between €590 and €913 ex-VAT, with specialized variants higher) supplemented by software licenses and custom/OEM contracts. Distribution combines marine electronics channels, direct OEM relationships with shipyards such as Chantiers de l'Atlantique and operators such as NEOLINE, and project-based sales to defense (DGA) and commercial fishing fleets. Leadership transitioned from founder Lamiraux to Christophe Michel in 2012, and the company participates in the Wind-Ship Association and European trade events (MTWE 2025, Wind for Goods 2025) to support international expansion.

Core offering

LCJ Capteurs designs and manufactures ultrasonic wind vane-anemometers that measure wind speed and direction using transit-time differences of ultrasonic signals between paired electroacoustic transducers. The product portfolio covers marine (CV7 series for sailboats, CV3F series for commercial vessels), terrestrial/industrial (SONIC-ANEMO series), and a forthcoming METEO-SONIC ultra-fast sensor, complemented by interface adapters, displays, and StatMETEO data software. All sensors are designed and assembled in France at the Vertou facility and use no-moving-parts technology to deliver maintenance-free, high-precision wind measurement for navigation, meteorology, and industrial applications.

Product overview

LCJ Capteurs is a designer and manufacturer of ultrasonic wind sensors (wind vanes and anemometers) serving marine and terrestrial markets since 1999. The product portfolio centers on two main sensor families: the CV7 Series for marine sailboats and the CV3F Series for professional/commercial vessels, plus the SONIC-ANEMO line for terrestrial and industrial applications. All sensors use ultrasonic transit-time measurement technology with no moving parts, providing maintenance-free wind measurement. The CV7 family includes base models (CV7, CV7-V), high-speed racing variants (CV7-C, CV7-HR), wireless versions (CV7SF2), and specialized versions with barometric sensors (CV7-BARO3), rotating mast support (CV7-RM), and various interface options (STBG universal, WindyPlug NMEA2000, USB). The SONIC-ANEMO terrestrial line offers versions with SDI-12, Modbus, and analog (0-10V, 4-20mA) outputs for weather stations, industrial, agriculture, and building management applications. Supporting software includes StatMETEO for data visualization/recording and Config_CV7 for sensor configuration. The company also announced METEO-SONIC, an ultra-fast model capable of 60 m/s measurements for professional meteorology, available from 2026. All products are designed and manufactured in France at the Vertou facility near Nantes.
