Wireless Humidity Sensor (RH) - High Accuracy

The high accuracy wireless humidity sensor allows you to monitor relative humidity, temperature and dew point from 10% - 90% RH. Ideal for monitoring humidity within greenhouses, industrial spaces, museums and humidors. They can also be used for residential applications such as controlling mold, mildew or dust mites. User customization allows you to set the frequency of readings and the ability to set thresholds for alerts.
