Sense4Boat Temperature Sensor

The Sense4Boat temperature sensor continuously monitors the temperature of your engine room and equipment with two independent probes on 3-meter cables. Connect them to your batteries, charger, solar regulator, or any other heat-sensitive equipment.

Every temperature variation is transmitted to the Sense4Boat control center every 30 seconds and compared to the thresholds you have defined. In case of an anomaly — rapid rise, critical temperature, or freezing — an alert is immediately sent.

1 year Sense4Boat subscription included — Cloud monitoring, instant alerts, mobile app. Renewal at €63/year after the first year.
⚠️ Important notice: This sensor is an informative monitoring tool. It is not certified as a fire alarm system by regulatory and competent authorities. Measurements should be used for informational purposes only.
Key Features

Comprehensive thermal monitoring for your boat

Two independent probes to simultaneously monitor multiple critical pieces of equipment

🌡️
Two Independent Probes
Monitor two pieces of equipment simultaneously with the two probes on 3-meter cables. Connect them to your batteries, charger, solar regulator, or any other at-risk component.
🔥
Rapid Rise Detection
The sensor detects temperature variations every 30 seconds. Any abnormally rapid rise triggers an immediate alert — an early sign of a fire starting.
❄️
Anti-Frost Alert
Be warned as soon as the temperature drops below a critical threshold. Protect your pipes, valves, and tanks from freezing during winterization or in cold regions.
🔋
Battery Monitoring
Connect a probe directly to your batteries to detect any overheating during charging cycles. A "battery boiling" phenomenon can be detected before it becomes dangerous.
💾
Internal Buffer Memory
When navigating out of NB-IoT network range, the sensor stores all measurements and transmits them as soon as connectivity is restored. No data is lost.
⚙️
Customizable Thresholds
Define your own alert thresholds: low, high, critical temperature, and maximum rate of rise. Each probe can have its own parameters depending on the equipment being monitored.
Why it's essential

Fire and frost: two threats to monitor

The engine room concentrates the equipment most exposed to thermal risks

🔥

The challenge of onboard thermal monitoring

Fire risk: Motor boats concentrate many at-risk pieces of equipment in a small space — engines, chargers, batteries, pumps, fuel. The temperature in the engine room can reach 70°C in normal operation. Conventional smoke detectors do not work above 55°C and are not designed for the humid environments of the engine room.

Frost risk: The outside temperature does not always reflect the inside temperature of the boat. Unexpected frost can irreparably damage pipes, valves, tanks, and cooling systems — costly repairs that can be avoided with proper monitoring.

Battery overheating: During charging cycles, faulty batteries can reach dangerous temperatures. Real-time monitoring allows an anomaly to be detected before it causes an incident.

Applications

Protect all your sensitive equipment

The two probes adapt to all equipment and all boat configurations

⚙️

Engine Room

Place a probe in the engine room to detect any abnormal temperature rise. Ideal for motor boats with diesel engines, pumps, and concentrated electrical equipment.

🔋

Batteries and Chargers

Attach a probe directly to your batteries or charger to monitor their temperature during charging cycles. Detect overheating before it becomes dangerous.

☀️

Solar Regulator

Connect a probe to your solar panel regulator to monitor its operating temperature and detect any heat-related malfunction.

🧊

Winterization and Anti-Frost Protection

During winterization, monitor the interior temperature of your boat to be alerted as soon as frost threatens your water circuits, tanks, and hydraulic equipment.

Alert System

Be alerted immediately, everywhere

As soon as a thermal anomaly is detected, you and your emergency contacts are notified simultaneously

📞
Voice Call
An automatic phone call alerts you as a priority — even if your phone is on silent.
💬
SMS
An SMS with the measured temperature and exceeded threshold is sent to you and your emergency contacts.
🔔
Push Notification
An instant push notification on your smartphone via the Sense4Boat app.
✉️
Email
A detailed email with the temperature history is sent to keep a record of each incident.
Configurable thresholds: low temperature · high temperature · critical temperature · rapid rise · sensor status report
Commissioning

Operational in less than 15 minutes

No electrical wiring, no central unit — simply attach the probes to the equipment to be monitored

1
Attach the probes
Slide the probes into the 10 mm holes provided for this purpose to attach them directly to your batteries, chargers or equipment. The 3 m cables allow for flexible installation.
2
Configure the app
Download the Sense4Boat app, add your sensor and define your alert thresholds for each probe. Customize the emergency contacts to be notified.
3
Monitor remotely
View real-time temperatures from anywhere. Receive instant alerts as soon as a thermal anomaly is detected on any of your equipment.
