FT009TW Wind Speed/Direction Sensor
The FT009TW Wind Speed/Direction Sensor is a sensor unit built around 5 measured parameters: outdoor temperature, humidity, wind speed, wind direction, and rainfall. Data reaches the console over 433 MHz RF, with no gateway, hub or subscription in the path. The sensor link is rated at 100 m in open area, which sets how far the outdoor unit can sit from the console.
Why this model
What the FT009TW Wind Speed/Direction Sensor gives a buyer
Verified measuring range
Outdoor temperature is specified at -40 °C to + 60 °C, accuracy: ±0.3 °C, so the range and tolerance are on the table before you sample.
Humidity specified both sides
Humidity is quoted as 1% to 99%, accuracy: ±3%, indoor and outdoor stated separately rather than as one blanket figure.
100 m sensor link
An open-area range of 100 m decides where the outdoor unit can be mounted; the figure is stated rather than left to the installer to discover.

Applications
Where the FT009TW Wind Speed/Direction Sensor is used
Farm and garden irrigation planning
Rain rate plus 24-hour, weekly, monthly and total accumulation lets an operator decide whether to irrigate without guessing at the weather report.
Roof, mast and yard exposure
Current, average and gust readings show when it is unsafe to work at height or leave equipment uncovered.
Wine cellar, greenhouse and storeroom humidity
Humidity is the variable that spoils stock; reading it continuously is what turns a storeroom into controlled storage.
Problems it removes
- Outdoor conditions guessed from a phone app that reports the nearest airport, not the site.
- Stock spoiling in storage because humidity was never measured, only assumed.
- No local wind record, so exposure limits at height are argued about instead of read.
Who buys it
- OEM customers pairing sensors to their own console
- Service and spares distributors
- System integrators building a multi-point install
Quality
How it is tested
Every FT009TW Wind Speed/Direction Sensor is aged before it leaves the factory and is checked on the same equipment the rest of the range uses: rainfall and waterproof testing, constant temperature and humidity chambers, radio link checks over the rated range, and vibration and smog aging equipment. A ten-person QC team inspects and tests in process, and the weather station line holds CE (GTS verification of compliance, RED 2014/53/EU) and FCC authorisation under FCC ID 2ALHJ-WS0300.
OEM and ODM
Building it under your brand
The FT009TW Wind Speed/Direction Sensor is available as an OEM or ODM build: own-logo and own-package builds and console artwork and unit selection (°C/°F, mm/inch, m/s or mph). MOQ runs from 300 to 1,000 pcs depending on model and delivery is normally 35 to 45 days; our own R&D team handles new development rather than subcontracting it.
Where it sits in the range
Inside Weather Sensors and Transmitters the FT009TW Wind Speed/Direction Sensor reads 5 parameters; if you need more on the same console, the FT025T Weather Station Sensor-UV carries 7; if the specification is heavier than the application needs, the Tank Liquid Level Indicator covers 3.
Questions buyers ask about the FT009TW Wind Speed/Direction Sensor
What is the wireless range of the FT009TW Wind Speed/Direction Sensor?
100 m in open area. Walls, metal cladding and other 433 MHz traffic reduce it, so plan the mounting point against the open-area figure rather than on top of it.
What temperature range and accuracy are specified?
Outdoor is -40 °C to + 60 °C, accuracy: ±0.3 °C. The full table is on this page; anything not in it is not a figure we will confirm by email.
What is the MOQ for the FT009TW Wind Speed/Direction Sensor?
MOQ is 300 to 1,000 pcs depending on the model. Tell us the model and the market and we will confirm which band it falls in.
What is the normal delivery time?
35 to 45 days for a normal production order. Sample lead time is shorter and is quoted per request.
Can we have our own logo and packaging?
Yes. OEM and ODM are standard here, including own-logo consoles and own-package builds, and our R&D team develops to customer requirements.
What certificates do you hold?
CE and FCC. The weather station range is covered by a GTS verification of compliance against RED 2014/53/EU and an FCC grant of equipment authorisation under FCC ID 2ALHJ-WS0300.
What is the warranty?
One year.
