What VoltSense monitors

Batteries

Up to three battery banks on 12, 24 or 48 V systems. See voltage and charging at a glance and catch a draining battery early.

Position and geofence

Live position and movement history, with an alert if the boat leaves its berth.

Bilge pump

A notification every time the bilge pump starts, with its full run history. Unusual activity stands out straight away.

Temperature and humidity

Cabin or engine-room climate, so damp and frost are caught before they cause damage. Humidity is measured with the e-paper display or an EYE Sensor.

Wireless add-ons

EYE Sensors for movement, hatches and doors, and extra temperature points. An e-paper display shows the readings on board.

Marinas and fleets

VoltSense HUB shows every boat in one view, for marinas, charter fleets and service companies.

VoltSense HUB for marinas and fleets

Every boat, its maintenance log and its alarms in one place. Give your team access to the data and reports they need, while owners' locations and personal details stay private.
