Calypso WeatherDot — Compact Precision for Environmental Monitoring
The Calypso WeatherDot is a high-precision, ultra-compact weather sensor that provides accurate readings of temperature, humidity and atmospheric pressure — all in a form-factor small enough to carry in your gear bag. Designed for precision shooters, field engineers, outdoor professionals and enthusiasts who require reliable environmental data, this sensor integrates seamlessly with the free Anemotracker app via Bluetooth.
Why the WeatherDot stands out:
-
Full environmental sensor suite — measures temperature (–15 °C to +60 °C), humidity (20 %-80 %), and pressure (500-1200 hPa) with high accuracy.
-
Bluetooth 5.1 connectivity — wirelessly sends real-time data to mobile devices for logging, analysis and integration with ballistic or meteorological workflows via the Anemotracker app.
-
Tripod-mount ready & ultra-portable — With a ¼-20 UNC tripod mount thread, easy to set up scenes, weigh only ~40 g, diameter approx. 43 mm making it one of the smallest professional weather sensors.
-
Wireless QI charging & long runtime — Recharge via wireless pad; up to ~150-400 hours of active use at low sample rate per various spec sources.
-
Designed for field reliability — Rugged construction, minimal complexity, ideal for deployment in field conditions for shooting, outdoors or remote telemetry.
Use the WeatherDot alone for ambient conditions or pair it with a wind meter (such as the Calypso Mini AB) for a full environmental set-up to feed your ballistic solver, range system or outdoor instrumentation.
