Full Stack Connectivity

Full Stack Connectivity

The BM-50, equipped with Bluetooth, WiFi, CAN, Ethernet, NMEA2000, and RS-485 (features vary by version), ensures seamless integration with the boat’s instrument backbone. Both Standard and Pro versions support NMEA2000, while the Pro version includes dual CAN interfaces for advanced connectivity. All versions offer mobile connectivity, providing a reliable link to essential systems.

Environmental Monitoring

Environmental Monitoring

Equipped with multiple sensor inputs, the BM-50 continuously monitors essential systems such as battery levels, shore power, bilge pump activity, door access, and more. Digital inputs for specific sensors (e.g., bilge, door, shore power) enable tailored monitoring configurations, all managed easily through the Sentinel app.

Remote Control Capabilities

Remote Control Capabilities

In the Standard and Pro versions, the BM-50 includes relay outputs, enabling remote control of connected devices such as lights or other onboard systems. Compatible with digital switching systems like CZone, this feature ensures critical devices can be activated or managed remotely, providing convenience and control even when you’re off the boat.

Power Efficiency and Safety

Power Efficiency and Safety

Built for efficient energy consumption, the BM-50 operates on 12-30 V DC and includes safety features like battery discharge  protection on the power supply. It’s designed to function reliably within a broad voltage range and challenging temperature conditions, ensuring continuous operation even in demanding marine environments.

PCB form

PCB form

The BM-50 can be delivered in PCB form, ready for seamless white-label integration into OEM marine products, enabling them to become “IoT ready” with advanced connectivity and real- time monitoring capabilities.

Sentinel Hub

Sentinel Hub

The Sentinel Hub enhances your boat’s monitoring capabilities by adding additional inputs and outputs to the system. It wirelessly connects to the Boat Monitor, simplifying the installation or retrofitting of extra sensors. Powered either directly or by its internal battery, this versatile device enables real-time monitoring of boat systems like engines, batteries, and security, providing reliable data and control for both boat owners and fleet operators.

Sentinel collaborates with trusted external partners to offer sensors designed for easy installation and reliable performance. Many of these sensors are wireless and battery-powered, enabling flexible placement on your boat without the need for complex wiring. With a battery life of up to 2 years, they ensure long-term monitoring and reduce the need for frequent maintenance, providing seamless integration with Sentinel’s advanced solutions.

Shore Power Sensor

Shore Power Sensor

Ensure reliable dockside power with the Shore Power Sensor. This sensor monitors your shore power connection and instantly alerts you via the Sentinel app if the connection is lost, keeping essential systems like refrigerators and battery chargers running smoothly while docked.

Gen-Set Ignition Sensor

Gen-Set Ignition Sensor

Take control of your generator with the Gen-Set Ignition Sensor. This sensor tracks generator activity, notifying you through the Sentinel app if it starts or stops unexpectedly, helping you ensure reliable power supply and prevent unauthorized use.

Temperature and Humidity Sensor

Temperature and Humidity Sensor

Maintain a comfortable and safe onboard environment with the T emperature and Humidity Sensor. This sensor continuously monitors cabin conditions, sending real-time updates and alerts through the Sentinel app if set thresholds are exceeded, helping you prevent issues like mold or overheating.

Air Conditioning Ignition Sensor

Air Conditioning Ignition Sensor

Manage your boat’s air conditioning effectively with the Air Conditioning Ignition Sensor. This sensor monitors the status of your AC system, letting you remotely check if it’s active and receive alerts if it turns on unexpectedly. It helps you optimize energy use and reduce unnecessary wear.

Motion Sensor

Motion Sensor

Protect sensitive areas on your boat with the Motion Sensor. This sensor detects movement in specific zones and immediately notifies you through the Sentinel app if any unusual activity occurs. Ideal for securing cabins or restricted areas, it provides an additional layer of security for peace of mind. COMFORT Air Conditioning Ignition

Boat Hatch Sensor

Boat Hatch Sensor

Ensure the security of your boat with the Boat Hatch Sensor, which monitors hatches for unauthorized access. If any hatch is opened unexpectedly, you’ll be alerted through the Sentinel app, allowing you to keep your vessel secure, even from a distance.

Tender Anti-Theft Sensor

Tender Anti-Theft Sensor

Keep your tender safe with the T ender Anti-Theft Sensor. This sensor detects any unauthorized movement or tampering, sending instant alerts to the Sentinel app. Whether you’re nearby or ashore, you can rest easy knowing your tender is protected.

Boat Door Sensor

Boat Door Sensor
