These sensors need periodic calibration to ensure reliable measurements. This paper proposes a dedicated smart calibration rig with a set of novel features enabling complete automation and parallel calibration. The calibration process is completely automated by developing a LabVIEW-based platform that controls the calibration environment for the sensor nodes under test, logs sensor data, generates an updated calibration equation and uploads it to the sensor node for next deployments. The results demonstrate the effectiveness of the sensor calibration rig. Keyphrases: Gas sensors calibration, IEEE 802.15.4, ZigBee, cross sensitivity, piecewise curve fitting
