General Description

It is intended for use on battery or other DC sources, up to 50 Volts. Not intended for use with AC Voltages. It is perfect for batteries, adapters, solar equipment, vehicles or machinery, and any other electrical appliance monitoring. The sensor triggers on voltage presence to voltage Absence and vice versa. The data is displayed as “Voltage Detected” or “No Voltage”.
• Detects presence or absence of Voltage
• Voltage presence detected above ~0.47 Volts
• Voltage absence detected below ~0.47 Volts
• Detects voltages up to 50 Volts
• Reverse voltage protection, up to 50 Volts

Principle of Operation

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 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. 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.

Features of Monnit ALTA Sensors
•   Wireless range of 1,200+ feet through 12+ walls *
•   Frequency-Hopping Spread Spectrum (FHSS)
•   Improved interference immunity
•   Improved power management for longer battery life **(12+ years on AA batteries)
•   Encrypt-RF® Security (Diffie-Hellman Key Exchange+AES-128 CBC for sensor data messages)
•   Onboard data memory stores up to 512 readings per sensor:
– 10-minute heartbeats = 3.5 days
– 2-hour heartbeats = 42 days
•   Over-the-air updates (future proof)
•   Free iMonnit basic online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email
*Actual range may vary depending on environment.
**Battery life is determined by sensor reporting frequency and other variables. Other power options are also available.
