by The Leading Enterprise Internet of Things Solution Wireless 0-20 mA Current Meters General Description Features of Monnit ALTA Sensors The ALTA Wireless 0-20 mA Current Meter is capable of Wireless range of 1,200+ feet through 12+ walls * measuring the current off another device or sensor up Frequency-Hopping Spread Spectrum (FHSS) to 20mA VDC. Improved interference immunity Improved power management for longer battery life ** Measures current up to 20 mA (12+ years on AA batteries) Encrypt-RF Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages) Principle of Operation Datalogs 2000 to 4000 readings if gateway connection is lost (non-volatile flash, persists through the power By connecting the leads on the ALTA Wireless cycle): 0-20 mA Current Meter to the positive and ground - 10-minute heartbeats = ~ 22 days terminals of another device, the sensor can measure - 2-hour heartbeats = ~ 266 days the current and send data to the iMonnit Online Sensor Over-the-air updates (future proof) Monitoring and Notification System. The data is stored Free iMonnit basic online wireless sensor monitoring in the online system and can be reviewed and exported and notification system to configure sensors, view as a data sheet or graph. Notifications can be set up data and set alerts via SMS text and email through the online system to alert the user when certain Actual range may vary depending on environment. thresholds have been met or exceeded. * ** Battery life is determined by sensor reporting frequency and other variables. Other power options Example Interfacing are also available.
