Anemometer TFA-Dostmann Spring Breeze Black

The TFA‑Dostmann Spring Breeze Black combines a wireless anemometer with a thermo‑hygro transmitter to measure outdoor wind speed, outdoor temperature and humidity, while also monitoring indoor temperature and humidity. Measured values are transmitted to the base station and shown on a colour display with an animated wind graphic; historical data is stored for up to one year. An integrated electronic barometer measures air pressure and provides a short weather forecast based on pressure changes. Time and date are received via the DCF‑77 radio signal. The unit is powered by AAA batteries; the display can be kept permanently lit when connected to an external power supply.

Advantages

The device provides combined wind, temperature and humidity monitoring in a compact black housing, with wireless transmission at 433 MHz. The colour display shows an animated wind turbine and coloured bars to visualise wind force, and offers two brightness levels. The station records highest and lowest values, supports alarm limits, and calculates dew point and wind chill. Historical trends for up to one year enable review of past conditions.

Suitable for

• Home weather monitoring (indoor and outdoor)
• Garden and balcony wind measurement
• Monitoring nursery, bedroom, cellar or garage climate (additional transmitters supported)
• Hobby meteorology and trend tracking

How to use

Install the outdoor thermo‑hygro transmitter and wind sensor in a location representative of the measured site, avoiding strong obstructions and mounting the wind sensor where it receives unobstructed airflow. Place the base station indoors within range of the transmitters. The measured data are sent wirelessly to the base station and displayed automatically. Set the clock via DCF‑77 reception and configure alarm limits or additional transmitters through the base station menu. If continuous display illumination is required, connect the base station to the external power supply; otherwise operate on AAA batteries.

Recommendations

Mount the wind sensor at a clear, elevated position away from buildings or trees for accurate wind readings. For reliable temperature and humidity measurements, avoid direct sunlight and heat sources. Use additional transmitters to monitor other rooms such as the nursery or cellar, and check battery status periodically to ensure uninterrupted data transmission.
