Welcome to SENSE4BOAT, a unique boat monitoring system of the next generation. S4B is designed using cutting-edge Internet-of-Things (IoT) technology to monitor all the vital parameters of the boat and to detect potential threats long before they become a real hazard.

All the sensors and the measurements collected from the various sensors can be checked anywhere with the SENSE4BOAT mobile application. When a critical alert is generated, the owner, and optionally the marina where the boat is berthed in, will receive a voice call with a detailed description of the hazard, as well as an email, SMS, and a push notification on the mobile application. The application also logs all alerts and warnings generated by the sensors.

Each of the sensors is directly connected to the Internet so there is no need for an expensive and complicated central unit, it is powered by internal batteries so it does not drain the boat’s batteries and the installation is done in several minutes.


In order for the sensors to work, they need to be in the area covered by the Sigfox Network, the world’s largest IoT network. No SIM cards are required and only a moderate annual subscription. Please check the coverage and the strength of the Sigfox Network signal here.
