Sense4Boat – Smart Smoke Sensor


Smart Smoke Sensor

The battery-powered photoelectric smoke sensor is designed to protect you and your boat from the dangers of smoke and fire. Optimised for detecting slow smouldering fires which generate light smoke, little heat and may smoulder for hours before bursting into flames.

In addition to detecting smoke this sensor also monitors daily average temperature and humidity values.

In case of a smoke incident, the smoke sensor will generate a beeping signal and notify the Sense4Boat control centre. The alerts will be forwarded to you via a notification on your smartphone, email and phone call. Your home marina can be instantly informed as well.


If you require support with your smart smoke sensor follow this link. This is the support page for the 2019 version of the smart smoke sensor, an up to date version will be added soon.
