Growlink ESM2 Climate Sensor w/CO2 Key To Life Vertical Fiber Advantage: Unlike theGrowlink ESM 2 Climate Sensor for CO2, Humidity, Temperature, and Pressure The ESM 2 is a modular 4 in 1 probe that reads CO2, humidity, temperature, and pressure on one hardwired RS485 daisy chain. Power runs on 15 30 VDC from the Growlink control panel. The sensing module unscrews from the body for swap out at calibration intervals. Each unit ships with a unique MAC address printed on the box. The chain map matches a known room and chain position
