by The Leading Enterprise Internet of Things Solution Wireless DC Voltage Detection Sensors (0-50 VDC) General Description Features of Monnit ALTA Sensors The ALTA DC Voltage Detector detects the presence or Wireless range of 1,200+ feet through 12+ walls * absence of electricity. It is intended for use on battery or Frequency-Hopping Spread Spectrum (FHSS) other DC sources, up to 50 Volts. Not intended for use Improved interference immunity with AC Voltages. It is perfect for batteries, adapters, Improved power management for longer battery life ** solar equipment, vehicles or machinery, and any other (12+ years on AA batteries) electrical appliance monitoring. The sensor triggers on Encrypt-RF Security (Diffie-Hellman Key Exchange voltage presence to voltage Absence and vice versa. + AES-128 CBC for sensor data messages) The data is displayed as Voltage Detected or No All ALTA sensors now have up to 3200 readings: Voltage. - 10-minute heartbeats = 22 days - 2-hour heartbeats = 266 days Detects presence or absence of Voltage Over-the-air updates (future proof) Voltage presence detected above ~0.47 Volts Free iMonnit basic online wireless sensor monitoring Voltage absence detected below ~0.47 Volts and notification system to configure sensors, view Detects voltages up to 50 Volts data and set alerts via SMS text and email Reverse voltage protection, up to 50 Volts Actual range may vary depending on environment. * Battery life is determined by sensor reporting ** Principle of Operation frequency and other variables. Other power options are also available. The ALTA DC Voltage Detector detects the presence or absence of voltage. The sensor triggers on voltage presence to voltage absence and vice versa. The data Wireless Range Comparison Wireless Range Comparison is displayed as Voltage Detected or No Voltage. If no change is observed within the heartbeat interval, the state is continuously reported on the heartbeat interval. Monnit ALTA Transitions and heartbeat data is logged into a cloud service. The user can set the system to send an alert on either state, or on the transition of states.
