by The Leading Enterprise Internet of Things Solution Wireless Humidity Sensors General Description Features of Monnit ALTA Sensors The ALTA Wireless Humidity (RH) Sensor allows you to Wireless range of 1,200+ feet through 12+ walls * accurately monitor the relative humidity of the air within Frequency-Hopping Spread Spectrum (FHSS) a room or enclosure. Improved interference immunity Improved power management for longer battery life ** Measures relative humidity, temperature and dew (12+ years on AA batteries) point with high accuracy Encrypt-RF Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages) Datalogs 2000 to 4000 readings if gateway connection is lost (non-volatile flash, persists through the power Principle of Operation cycle): - 10-minute heartbeats = ~ 22 days The ALTA Wireless Humidity (RH) Sensor measures the - 2-hour heartbeats = ~ 266 days relative humidity at the device. The sensor returns RH Over-the-air updates (future proof) and temperature values to the iMonnit Online Sensor Free iMonnit basic online wireless sensor monitoring Monitoring and Notification System. The system and notification system to configure sensors, view calculates dew point from the data and stores all three data and set alerts via SMS text and email data points in the online system where the data can be reviewed and exported as a data sheet or graph. Actual range may vary depending on environment. * Notifications can be set up through the online system Battery life is determined by sensor reporting ** to alert the user when defined thresholds have been frequency and other variables. Other power options met or exceeded. are also available.
