Monitor humidity remotely and get notified fast when it breaches preset limits.

Monnit’s Enterprise Wireless Humidity Sensor measures the relative humidity (RH) of the air within a room or enclosure.

Whether it’s artifacts or data, you know that maintaining a relative humidity (RH) between 40–60% percent can be the difference between proper preservation and irreversible loss.

This Humidity Sensors remotely monitors RH with a +/- 3% accuracy (between 10–90% RH), temperature, and dew point in facilities or enclosures. If the humidity exceeds your specified limits, these scientific-grade sensors alert you via text, email, or call for swift correction in real time.

Its not the heat, it’s the humidity

Monnit’s Wireless Humidity Sensor measures the RH at the device. The sensor returns RH and temperature values to the iMonnit Online Sensor Monitoring and Notification System. The system calculates dew point from the data and stores all three data points in the online system where the data can be reviewed and exported as a data sheet or graph. Notifications can be set up through iMonnit to alert you when defined thresholds are met or exceeded.

This sensor can be customised to yours needs with optional 3 – 25’ leads and seven-month NIST certification. Additionally, two replaceable 1.5 V AA-sized batteries are included with up to 10 years battery life.
