aSENSE Display is an all-digital, low-cost transmitter for installation in the climate zone. It measures both CO2 concentration and temperature in the ambient air, transforms the data into output signals and sends these values to a comprehensive system. The aSENSE is a key component for climate control of buildings and other processes. It is also a cost-efficient gas alarm sensor for spaces where carbon dioxide gas is a potential danger.

This maintenance free device helps you save money by decreasing your energy consumption while creating a healthier indoor climate. This is achieved in normal indoor applications using the Senseair ABC algorithm.
