Abstract: In order to accurately detect the temperature and humidity in curing facilities, WSD02-2 temperature and humidity monitor was developed with SCM and new type digital temperature sensors. The range of temperature detection was from -55 to +125℃, and the accuracy reached 0.1℃. The temperature and humidity of 10 points in curing facilities could be detected simultaneously with high accuracy and stability, and signals could be transmitted distantly. The monitor could meet the demands of accurately monitoring temperature and humidity during flue-curing.
