Monnit wireless humidity sensors allow you to monitor the relative humidity of the air within a room or enclosure. Ideal for monitoring humidity within greenhouses, industrial spaces, museums, saunas and humidors. They can also be used for residential applications such as controlling mold, mildew or dust mites.
Available with NIST traceable certificate good or 7 months. (In the Customize section above select NIST Certified.)
NIST certified sensors orders may take up to 6 weeks to prepare, certify and ship.

The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries (included with purchase). This sensor is also available with a line power option. The line powered version of this sensor has a barrel power connector allowing it to be powered by a standard 3.0 - 3.6 V power supply (Included with Line Power option upgrade). The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted operation in the event of line power outage.
Power options must be selected at time of purchase, as the internal hardware of the sensor must be changed to support the selected power requirements.
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
