About TERA Sensor

TERA Sensor premises in Rousset, near Aix-en-Provence

WHO WE ARE

We develop particle sensing technologies

TERA Sensor designs and manufactures particulate matter sensors and optical particle counting technologies for OEMs and professional monitoring systems.

Based in Rousset, in the south of France, our team combines particle measurement expertise, sensor engineering, electronics and industrialization capabilities to develop sensing solutions designed for real-world integration.

From compact PM sensors to precision optical particle counters, our technologies are used by manufacturers and integrators across environmental monitoring, building systems, industrial applications and controlled environments.

MEASUREMENT EXPERTISE

Built around measurement expertise

TERA Sensor’s technologies are developed around one core objective: obtaining useful and repeatable particle measurements under real operating conditions.

Our teams work across optical measurement, aerosol behaviour, airflow, electronics, signal processing and calibration to understand how each element of a sensing system influences its final performance.

This multidisciplinary approach allows us to develop sensors not only as components, but as measurement technologies designed for integration into professional systems.

DESIGNED IN FRANCE

Designed and manufactured in France

Our sensor technologies are developed in Rousset, near Aix-en-Provence, where engineering, prototyping and production capabilities are brought together within the Groupe TERA ecosystem.

Keeping development and manufacturing close together enables faster design iterations, tighter control of product quality and direct technical support for OEM customers.

GROUPE TERA

Part of Groupe TERA

TERA Sensor is part of Groupe TERA, a French technology group specializing in air quality, environmental measurement and related technologies.

Being part of this ecosystem gives TERA Sensor access to complementary expertise in measurement, electronics, engineering and industrialization while maintaining a dedicated focus on particulate matter sensing technologies.
