    eYc GS07 is a state-of-the-art non-dispersive infrared(NDIR)carbon dioxide(CO2 )transmitter. The direct insertion design and miniature size make it easy to install in the ventilation duct. eYc GS07 provides measurement in analog outputs(0 … 10 V, 4 … 20 mA)and digital output(RS-485 Modbus RTU protocol). With CO2 demand controlled ventilations, eYc GS07 helps to save money by decreasing the energy consumption while maintaining a healthier indoor climate
