Garmin tempe External Wireless Ambient Temperature Sensor, ANT+, 10 m Water Resistant, CR2032 3V

Overview

The Garmin 010-11092-30 is an external wireless temperature sensor that sends ambient temperature to compatible Garmin devices using the 2.4 GHz ANT+ wireless communications protocol. It runs on a user-replaceable 3 V CR2032 battery (up to 1 year of typical battery life), is water resistant to 10 m (32.9 ft), and operates from -4°F to 140°F (-20°C to 60°C).

On a boat, this is a simple way to track real outside-air temperature without your device being influenced by body heat, a warm helm, or a sun-baked console. Clip it where it can “breathe” in open air, then view the reading on your compatible handheld or wearable nearby.

Key features

• Wireless temperature sensor for compatible Garmin devices using ANT+ (2.4 GHz)
• Operating temperature range from -4°F to 140°F (-20°C to 60°C)
• Water resistant to 10 m (32.9 ft) for use in wet, exposed conditions
• User-replaceable CR2032 3 V battery with up to 1 year of typical battery life
• External reading helps avoid heat soak and body-heat influence that can skew onboard temperature checks
• Pairs from close range (within about 9.8 ft / 3 m), which suits cockpit, cabin, or deck monitoring when your display device is nearby

Installation and setup

The sensor snaps into its clip and is meant to attach to a secure strap or loop. For marine use, common spots include a bimini or dodger strap, a life jacket lash point, a cockpit bag strap, or a rail-mounted gear lanyard, as long as the sensor is exposed to ambient air.

During pairing, keep the sensor close to the receiving device (within about 3 m / 9.8 ft) and away from other ANT+ sensors. Once paired, it can be used as the temperature source your device displays instead of relying on its internal sensor.

Compatibility and system notes

This is a self-powered wireless sensor. It does not wire into a boat’s 12 V or 24 V system and it does not connect to NMEA networks. Temperature is sent over ANT+ and will only appear on Garmin devices that support pairing with this type of temperature sensor.

Use cases on board

Useful for skippers who want a quick read on real deck temperature during coastal cruising, a night watch, or early-morning runs, and for anglers who track air temperature shifts that can affect conditions on the water. It also fits well on small craft where you carry a compatible handheld or wear a compatible watch and want the reading to stay consistent while you move around the boat.

Maintenance and care

Rinse salt spray off with fresh water when needed and let it dry before storage. If readings stop updating, replace the CR2032 battery and confirm the battery cover is properly seated and secured.
