The Tesa WS1151 is an excellent choice if you want useful information about the weather around your home without the complexity of a full wind and rainfall weather station.
A separate wireless outdoor sensor measures temperature and humidity outside, while the indoor display monitors your indoor temperature, humidity and barometric pressure. The result is a clear picture of conditions both inside and outside your home, together with information showing how the weather may be changing.
- Barometric pressure is particularly useful because changes in air pressure can indicate an approaching change in weather. The Tesa WS1151 displays current pressure, a 24-hour pressure history graph and a tendency arrow, then uses changing pressure to provide simple weather forecast icons.
The display also includes moon phase, time, date and calendar information, making the Tesa WS1151 an attractive everyday weather display for the home, bach or office.
Follow Changing Weather Conditions
- The Tesa WS1151 measures:
- outdoor temperature
- outdoor humidity
- indoor temperature
- indoor humidity
- barometric pressure
It also records minimum and maximum temperature and humidity readings, allowing you to see the extremes reached since the records were last reset.
The outdoor sensor communicates directly with the indoor display using a wireless radio signal, with a specified transmission range of up to 100 metres in open conditions.
No home Wi-Fi or internet connection is required.
Barometer, Pressure History and Weather Forecast
The Tesa WS1151 does more than simply show current temperature and humidity.
Its built-in barometer measures atmospheric pressure and displays a 24-hour pressure history graph, allowing you to see whether pressure has been rising or falling.
A pressure tendency indicator makes the trend easy to recognise, while forecast icons use changing barometric pressure to indicate the expected general weather trend.
This gives you useful information about how conditions are developing rather than simply showing what the weather is doing at that exact moment.
Moon Phase, Time and Calendar
The Tesa WS1151 also displays the current moon phase, along with time, date and a perpetual calendar.
The moon-phase display shows the progression through the lunar cycle, including new moon, crescent, quarter, gibbous and full moon phases.
The indoor console can be either free-standing or wall mounted and includes an LED backlight for easier viewing when required.
Simple Battery-Powered Operation
Both the Tesa WS1151 display and outdoor sensor are battery powered, so the station does not need to be positioned beside a mains power outlet.
The indoor receiver uses three AA batteries, while the outdoor temperature and humidity sensor uses two AAA batteries.
TESA specifies more than two years of battery life for the remote sensor under normal operating conditions.
Why Choose the Tesa WS1151?
- Simple home weather monitoring — see indoor and outdoor temperature and humidity together with barometric pressure.
- See how the weather is changing — a 24-hour pressure graph and tendency indicator help show whether atmospheric pressure is rising or falling.
- Weather forecast icons — changing barometric pressure is used to indicate the expected general weather trend.
- Moon phase display — follow the current stage of the lunar cycle directly on the console.
- Minimum and maximum records — see the temperature and humidity extremes recorded by the station.
- No Wi-Fi or internet required — the outdoor sensor communicates directly with the indoor display by wireless radio signal.
- Flexible placement — battery-powered operation and a wall-mount or free-standing display make installation straightforward.
The Tesa WS1151 is particularly well suited to home and hobbyist users who want an uncomplicated weather station for temperature, humidity and barometric-pressure monitoring, with the added interest of weather trends and moon phase.
FAQ’s
Does the Tesa WS1151 measure rainfall or wind?
No. The Tesa WS1151 monitors indoor and outdoor temperature and humidity together with barometric pressure.
It is designed for customers wanting straightforward home weather monitoring rather than a complete wind and rainfall weather station.
Does the Tesa WS1151 need Wi-Fi or an internet connection?
No. The outdoor sensor sends its readings directly to the Tesa WS1151 indoor display using a wireless radio signal.
The station does not require home Wi-Fi, internet access or an online weather service.
How does the Tesa WS1151 weather forecast work?
The Tesa WS1151 monitors changes in barometric pressure. Rising and falling pressure trends are used to provide forecast icons indicating the expected general weather trend.
It is a local pressure-based forecast rather than an internet weather forecast.
Does the Tesa WS1151 show the moon phase for the Southern Hemisphere?
The Tesa WS1151 correctly shows the current stage of the lunar cycle, but the moon-phase graphic itself uses Northern Hemisphere orientation. In New Zealand the illuminated side of the Moon will therefore appear reversed compared with the icon during waxing and waning phases.
Can I put the Tesa WS1151 outdoor sensor anywhere outside?
The outdoor temperature and humidity sensor should be positioned where it can measure representative outdoor conditions and communicate reliably with the indoor display. Avoid locations where direct sunlight or other local heat sources could distort the temperature reading.
Power requirements:
- Receiver: 3 x AA alkaline batteries (not included)
- Wireless sensor: 2 x AAA alkaline batteries (not included)
