Aranet CO2 and Temperature Sensor | 0-9999 ppm Wireless PRO Ballasts The main effect is thatAranet PRO CO2 Sensor for Wireless Monitoring The Aranet PRO sensor pairs to an Aranet PRO base station over the Sub GHz US920 band. CO2 reads from 0 9999 ppm at (30 ppm + 3%), and temperature reads 0 50C at 0. 3C. It also logs atmospheric pressure from 300 1100 hPa. An IP67 ASA plastic enclosure lets it ride out the humidity of a working grow room. Wireless CO2 Sensor for Greenhouse and Grow Rooms Line of sight radio reaches up to 3 km, so one base
