eSENSE is a CO2 transmitter for climate control and fits directly on top of EU electrical junction box standards. The units is available both with and without display for fixed installation in the climate zone. The transmitter helps you to save money by decreasing your energy consumption while creating a healthier indoor air climate. eSENSE measures CO2 concentration in the ambient air up to 2000 ppm and transform the data into a analogue 0/2-10 V / 4-20mA output signal.


-Two analogue outputs.

-Internal automatic self-diagnostics.

-Maintenance-free in normal applications.

-Cost-optimized for connection to DDC:s.

-Prepared for complementary passive temperature element (model -Tr).

-Different housing options.



eSENSE is an extremely cost-optimized sensor solution for climate control of buildings and other processes. By controlling the ventilation based on actual demand, it helps you decrease your energy consumption and yet have a healthy indoor climate! The different housing options makes the eSENSE available to almost any application or environment for example in greenhouses, residential and commercial buildings. eSENSE -Tr is also prepared for quick mounting of a complementary passive temperature element, which can easily be done by the customer.
