Sense4Boat – Smart Heat Sensor


Smart Heat Sensor

The sensor continuously monitors (every 6sec) the temperature in an enclosed space (such a the engine room or electrical cabinets) and warns you about extreme temperatures or a sudden temperature rise as a possible indication of fire. The sensor can also warn you about low temperatures which might lead to freezing. The alert is delivered to the boat owner and all his emergency contacts via an automated voice call, SMS, email and push notifications. Optionally, the alert can also be shared with the selected Marina Link providers (marina, yacht service), enabling them to swiftly react and prevent potential disaster. All temperature measurements can be monitored via a user-friendly smartphone application.

The sensor is designed to operate at high temperatures on long terms (85°C) and even up to 5min @ temperature of 130°C.
