## Summary description

TFA Spring Breeze Black is a battery-powered weather instrument combining anemometer (wind speed), indoor hygrometer, indoor and outdoor thermometer with trend display for temperature. It uses AAA 1.5 V batteries and transmits outdoor sensor data wirelessly at 433 MHz. Compact dimensions (208×26×140 mm) suit home, garden or hobby weather monitoring.

## Long description

TFA Spring Breeze Black is a battery-powered weather instrument that combines an anemometer for wind speed measurement with an indoor hygrometer and indoor/outdoor thermometers. The unit displays current values and trends on a colour-illuminated screen and receives outdoor sensor data wirelessly at 433 MHz. Compact dimensions (208 × 26 × 140 mm) and battery operation make it suitable for home, garden and hobby weather monitoring.
Advantages
The integrated anemometer shows wind force with an animated graphic while coloured bars indicate relative strength, and wind turbine animation corresponds to measured speed. Outdoor temperature and humidity are transmitted wirelessly to the base station at 433 MHz so the outdoor sensor can be mounted at a distance from the display. The display shows temperature trends and stores historical values for review over time. An electronic barometer provides air pressure readings and a simple weather symbol based on pressure changes. Room temperature and humidity are measured locally to support indoor climate control. The display offers two brightness levels and can be permanently lit when the unit is connected to an external power supply. Additional functions include alarm limits for values, display of highest and lowest readings, dew point and wind chill calculation, and automatic time/date reception via DCF-77.
Suitable for
Monitoring wind speed and local weather conditions at a private home or garden
Measuring indoor temperature and humidity for climate control in living spaces
Hobby meteorology and basic data logging of weather trends over time
Monitoring temperature and humidity in secondary rooms such as nursery, cellar or garage (additional transmitters supported)
Key specifications
Power: AAA 1.5 V batteries for both base unit and outdoor transmitter (battery-powered)
Wireless transmission: 433 MHz for outdoor sensor data
Measures: wind speed (anemometer), temperature (indoor and outdoor), relative humidity (indoor and outdoor), air pressure (electronic barometer)
Display: colour-illuminated screen with two brightness levels and animated wind graphic
Dimensions: 208 × 26 × 140 mm
Time synchronization: DCF-77 radio-controlled time and date reception
Additional sensors: supports connection of up to two further transmitters for temperature and humidity
How to use
Install AAA 1.5 V batteries in the base unit and in the outdoor thermo‑hygro transmitter according to the polarity markings. Mount the outdoor sensor in a sheltered, representative location away from direct heat sources and not in direct sunlight; ensure the anemometer is exposed to unobstructed airflow for accurate wind readings. The outdoor transmitter sends data to the base station at 433 MHz automatically after installation; the base station receives the DCF-77 signal to set time and date. Use the display controls to view current values, trend indicators, stored high/low values, and calculated dew point or wind chill. To keep the display permanently lit, connect the base unit to an external power supply following the manufacturer’s instructions.
Usage recommendations
For reliable outdoor measurements, place the transmitter and anemometer at the recommended height and away from buildings or obstructions. Replace batteries before low-voltage warnings appear and regularly check sensor mounts for secure positioning. When comparing wind data with other instruments, allow for local variation caused by nearby structures or vegetation.
