Monitor Your Boat's Temperature From Anywhere
The Garmin OnDeck™ Temperature Sensor (Part No. 010-13009-02) gives you real-time temperature readings from anywhere your phone has a signal. Whether you're watching for engine compartment heat, monitoring a live well, or keeping tabs on cabin conditions, this sensor feeds data directly into the ActiveCaptain® app so you always know what's happening aboard — even when you're not there.
It integrates seamlessly into the Garmin OnDeck™ remote monitoring ecosystem, which also tracks battery status, bilge activity, shore power, and more. Set custom alarm thresholds so you're notified the moment something needs your attention.

Parts Desk Insights
Best use case: This sensor is the right choice for boaters who want early warning on heat-related issues — particularly those with enclosed engine compartments, live wells, or refrigeration units aboard. It's especially valuable for trailered boats left in storage or at a marina, where temperature spikes from sun exposure or equipment faults can go unnoticed for days. Pair it with the OnDeck™ 24V Relay Switch if you need active control alongside your monitoring, or the OnDeck™ Shore Power Sensor (Hard-Wired) for a permanent installation.
