About TERA Sensor
Particle sensing technologies engineered and manufactured in France.
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.
Designed in France
Sensor technologies developed by our engineering teams.
OEM focused
Products designed for integration into customer equipment and monitoring systems.
Measurement expertise
Deep expertise in optical particulate matter measurement.
Industrial approach
From sensor architecture and prototyping to production-ready solutions.
More than a sensor manufacturer
Measurement performance depends on much more than the sensing element. Our expertise extends from particle measurement physics to electronics, mechanical integration and industrialization.
Sensor technologies
We develop our own particulate matter sensing architectures and products for different measurement requirements.

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.

- Validation & characterization
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.
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.
