A human and technological adventure

Well-known in the marine industry, Mr. Lamiraux founded LCJ Sensors in 1999 after a successful career at MLR Électronique (radio-positioning and GPS pioneer) with the aim to lead the way in robust and accurate wind sensors, designed for marine use, with no moving parts, that are compact, lightweight, lowconsumption and affordable for all.  

Our company is a pioneer in the field of ultrasonic wind measurement for all, and this remains our aim.  

Our range has expanded along with the development of components, and our catalogue now provides solutions for all marine or terrestrial applications 

Christophe Michel, who joined the initial team, took over the company in 2012. He boosted the terrestrial sector, and developed product export, supported by the “Pays de la Loire” region and the “Nantes-Saint-Nazaire” Chamber of Commerce.
