Our multi-gas microsensor products

EnviCam® series

Our flagship product line EnviCam-3x is microelectronic gas sensors for IoT & Industry 4.0 solutions.

These microchips are based on our patented CMOSEnvi™ technology, integrating several nanotech-based sensing materials within a CMOS-compatible process. The current products are integrated into a SiP package measuring 10 x 5 x 0.9 mm³, with power consumption below 50 µW continuously (up to 1 measurement per second).
