by The Leading Enterprise Internet of Things Solution Wireless Water Detection Sensors General Description Features of Monnit ALTA Sensors The ALTA Wireless Water Detection Sensor detects the Wireless range of 1,200+ feet through 12+ walls * presence or non-presence of water. Frequency-Hopping Spread Spectrum (FHSS) Improved interference immunity Improved power management for longer battery life ** Water Detection (12+ years on AA batteries) Encrypt-RF Security (Diffie-Hellman Key Exchange 3 ft leaded wires + AES-128 CBC for sensor data messages) Immediately detects water 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 Water Detection Sensor detects - 2-hour heartbeats = ~ 266 days when water is present by completing the circuit between Over-the-air updates (future proof) the two leaded wires. When water is present the sensor Free iMonnit basic online wireless sensor monitoring will immediately turn on the RF radio and transmit the and notification system to configure sensors, view data to the wireless gateway and iMonnit Online Sensor data and set alerts via SMS text and email Monitoring and Notification System, allowing the user to immediately receive an SMS text or email alert. The Actual range may vary depending on environment. * sensor can be configured to detect both the presence Battery life is determined by sensor reporting ** and non-presence of water. frequency and other variables. Other power options are also available.
