Model aSENSE GH “Green House” is a transmitter for installation in the climate zone. The special coated PCB and extra dust/water protection filter make aSENSE GH suited for all kinds of greenhouses, incubators and similar environments. The unit measures both temperature and carbon dioxide concentration. aSENSE GH measures both temperature and carbon dioxide concentration in the ambient air, transforms the data into digital output signals and sends these values to a comprehensive system. The transmitter measures CO2 concentration in the ambient air up to 3000 ppm and transforms the data into an analogue 0/2-10 V / 4-20mA output signal.
