SENSE4BOAT
Read full descriptionHide full description
The SENSE4BOAT application provides an innovative service to all boat owners with a combination of lightweight sensors installed onboard a ship and an intuitive and deep application. Whenever one of the sensors installed onboard your boat registers any state or activity that could lead to potential damage to your boat, you will receive a notification, thus allowing you to take actions to prevent said damage. Additionally, SENSE4BOAT also offers you the unique option of allowing your marina to receive critical notifications at the same time as you do. This allows your marina to take immediate action, preventing extensive damage and potentially even saving your boat altogether! SENSE4BOAT supports seven types of sensors: * Bilge sensor that will alert you whenever water accumulates in your bilge. Works equally for seawater intrusion and rainwater accumulation, * Smoke sensor which detects the presence of smoke * Heat sensor that monitors temperature in enclosed spaces, warning you of both high and low temperature, as well as rapid rises in temperature * Battery sensor that will alert you whenever the voltage of your batteries is outside the normal range, saving you significant amounts of money, * Temperature and humidity sensor that will warn you of high temperature and high levels of humidity * Docking assistance device which allows you to request docking assistance from your marina * Boat care device which allows your boat care company to inform you that all the arranged activities have been carried out
