Sense4Boat Boat Monitoring — NB-IoT Connected Sensors | Advanced Tracking
Your boat monitored 24/7, wherever you are
Sense4Boat smart sensors alert you in real-time as soon as an anomaly is detected onboard — water leak, battery discharge, overheating or freezing. No phone subscription, no complex wiring.
Boat monitoring reimagined
Sense4Boat is an IoT platform specifically designed for leisure boat monitoring. Unlike traditional GPS tracking systems, Sense4Boat monitors the internal state of your boat — what happens onboard when you're not there.
Each sensor communicates via the NB-IoT (Narrowband IoT) network, a long-range, ultra-low power cellular technology that allows for 5-year battery life on batteries, without consuming onboard electricity.
Data is centralized in the Sense4Boat cloud and accessible from the iOS and Android mobile app. In case of an anomaly, you receive an alert via voice call, SMS, email or push notification — and your marina or service provider can be alerted simultaneously.
Three sensors for complete protection
Each Sense4Boat sensor monitors a specific and critical risk for your boat. Used together, they cover all threats a boat at the dock or in a marina is exposed to.
- 2 independent floats on 3 m cables to monitor two water levels
- High water alarm before the situation becomes critical
- Self-diagnosis every 12h — confirmation that the sensor is working
- Internal buffer memory in case of network loss during navigation
- Installation without drilling or onboard electrical wiring
- Ideal for sailboats, motorboats, barges, and boats at the dock
- Simultaneous monitoring of 2 x 12V or 24V battery banks
- Deep discharge alarm to prevent irreversible sulfation
- Charging cycle monitoring: start, end and anomaly detected
- 3 m cables with protection fuses included
- Voltage history viewable in the mobile application
- Compatible with all marine batteries: AGM, gel, lithium, lead
- 2 probes to monitor engine room, chargers, and batteries
- Fire alarm: detection of abnormal rapid temperature rise
- Frost alarm: winterization protection for pipes and tanks
- Extended measurement range: −55°C to +125°C, ±0.5°C accuracy
- Measurement every 30 seconds for maximum responsiveness
- Ideal for boats in dry dock, winter storage and marina
