by The Leading Enterprise Internet of Things Solution Wireless 500 VAC Voltage Meters General Description Features of Monnit ALTA Sensors The Wireless 500 VAC Voltage Meter is an analog Wireless range of 1,200+ feet through 12+ walls * measuring device that reports the measured VACrms on Frequency-Hopping Spread Spectrum (FHSS) user specified intervals. Improved interference immunity Improved power management for longer battery life ** (12+ years on AA batteries) Wireless interface for measuring voltage Encrypt-RF Security (Diffie-Hellman Key Exchange Measures voltage up to 500 VACrms + AES-128 CBC for sensor data messages) Datalogs 2000 to 4000 readings if gateway connection Free iMonnit basic online wireless is lost (non-volatile flash, persists through the power sensor monitoring and notification cycle): system to configure sensors, view data - 10-minute heartbeats = ~ 22 days and set alerts via SMS text and email - 2-hour heartbeats = ~ 266 days Over-the-air updates (future proof) Free iMonnit basic online wireless sensor monitoring Principle of Operation and notification system to configure sensors, view data and set alerts via SMS text and email By connecting the leads on the Monnit Wireless 500 VAC Voltage Meter to the hot (black) and neutral (white) Actual range may vary depending on environment. * terminals of an AC power system, the sensor can Battery life is determined by sensor reporting ** measure the voltage and send data to the iMonnit Online frequency and other variables. Other power options Sensor Monitoring and Notification System. The data are also available. is stored in the online system and can be reviewed and exported as a data sheet or graph. Notifications can be set up through the online system to alert the user when Wireless Range Comparison certain thresholds have been met or exceeded.
