Smart Engine Compartment Heat Sensor
Protect your boat from engine-room fires and freezing conditions with Sense4Boat’s Smart Heat Sensor.










Advanced Fire and Freeze Monitoring
Designed for harsh marine environments, this rugged, marine-grade sensor continuously monitors temperature and alerts you instantly when rapid or extreme fluctuations occur—helping you catch issues before they escalate.
Why It's A "Must Have" Sensor
Early Fire Detection: Detects sudden temperature spikes linked to overheating or fire in engine compartments.
Freeze Risk Alerts: Monitors for low-temperature conditions to help prevent freeze damage in cold spaces.
Built Tough: Built to withstand engine-room fumes, humidity, and high heat. facebook.com+4sense4boat.
Simple & Independent: Battery-powered, no wiring or SIM needed—connects via global Sigfox network.


How It Works
1. Install & Activate — Hold the activation magnet for 5–7 seconds, then mount the sensor high in the engine room via screws or adhesive.
2. Continuous Monitoring — It tracks ambient temperature and watches for sudden rises or drops.
3. Threshold Comparison — Readings are sent to the Sense4Boat control center and compared to your set alarm thresholds.
4. Instant Alerts — If limits are breached, you—and your marina or service provider—receive notifications via app push, SMS, email, or voice call.
