FT009TR Rain Gauge Sensor (Weather Sensors Variant 2)
The FT009TR is a rain gauge sensor that measures rainfall from 0 to 9999mm with 0.3mm resolution below 1000mm and 1mm above, transmitting every 60 seconds over a 433MHz link. It uses four AAA alkaline cells and is designed to fit the same outdoor mounting system as other UCTECH s
What This Model Is For
The FT009TR is a rain gauge sensor that measures rainfall from 0 to 9999mm with 0.3mm resolution below 1000mm and 1mm above, transmitting every 60 seconds over a 433MHz link. It uses four AAA alkaline cells and is designed to fit the same outdoor mounting system as other UCTECH sensors, allowing a brand to expand a weather station line without redesigning the sensor interface. The sensor is built for long-term outdoor use with a sealed housing and internal ageing testing before shipment.
- Measures up to 9999mm of rain with 0.3mm resolution below 1000mm, suitable for extreme weather monitoring
- 60-second transmission interval ensures timely data updates without overwhelming the console
- 433MHz link reaches 100m in open air and around 30m through typical obstructions
- Shares the same mounting and power system as other UCTECH outdoor sensors for easy integration
- Uses four AAA alkaline cells with no solar assist, simplifying battery replacement and logistics

Where It Is Used
- Rooftop and garden weather stations sold under a distributor's own brand
- Agricultural and horticultural monitoring where precise rainfall data drives irrigation decisions
- Building services and cold chain sites needing to track roof or ground-level precipitation
- Marina and pool monitoring for storm surge and drainage planning
- School and visitor centre weather displays requiring accurate rainfall tracking
Who It Is For
- Consumer electronics brands adding rain measurement to an existing weather station line
- Distributors replacing a rain sensor that failed after one season due to moisture ingress
- Agricultural equipment suppliers bundling sensors with irrigation or greenhouse controls
- Integrators who need a battery-powered sensor because trenching cable is not feasible
Problems It Solves
- Rain sensors that report only totals and miss short bursts or storm intensity
- Sensors with poor resolution that round 0.2mm to 1mm, losing detail in light rain
- RF links that fail beyond 30m, requiring a gateway or cabling in larger sites
- Sensors that require frequent battery changes due to high power draw or no solar assist
Technical Features
- Rain volume measurement from 0 to 9999mm with OFL indication if outside range
- Resolution of 0.3mm below 1000mm, 1mm above 1000mm
- Rain accuracy of plus or minus 1mm under 15mm, plus or minus 7 percent from 15mm to 9999mm
- Transmission interval of 60 seconds
- 433MHz one-way transmission with 100m open area range and around 30m in most conditions
- Outdoor temperature sensing from -40 to +60 degrees C at 0.3 degrees C accuracy
- Humidity sensing across 1 to 99 percent RH at 3 percent accuracy
- Integrated solar panel not present; powered by four AAA alkaline cells

Materials and Construction
- Moulded plastic housing for the rain collector and sensor body
- Weather sealed battery compartment sized for 4 x AAA cells
- Integrated rain funnel and internal drainage channel
How It Is Made
Sensor sub-assemblies are populated and soldered on our own assembly line
Rain funnel and internal channels are checked for alignment and flow before sealing
Housings are sealed and tested on rainfall and waterproof test equipment
Every unit is ageing tested before it leaves the factory
Quality Control
- Rainfall and waterproof testing on the assembled sensor body
- Constant temperature and humidity chamber runs covering the -40 to +60 degrees C claim
- Vibration testing to reproduce mast and transport loading
- Smog ageing to check the housing and seals
- Final ageing test on every unit before packing
Customisation Options
- Own-label printing and retail packaging
- Console pairing to a customer's existing UCTECH-protocol display
- Alternative battery configurations on request
- Manual and quick start guide in the destination language
Compared With the Alternatives
vs Sensors with no resolution below 1mm
0.3mm resolution captures light rain and short bursts that would otherwise be lost
vs Wired rain sensors
No cable run required, but limited by battery life and 100m range ceiling
vs LoRa-based rain sensors
433MHz is lower cost and sufficient for single-site monitoring; LoRa is better for large or multi-sensor sites
Use Guide
- Mount the sensor clear of overhangs and obstructions to avoid splash and blockage
- Ensure the rain funnel is level and unobstructed by debris or leaves
- Replace the four AAA alkaline cells every 12 to 18 months depending on usage and climate
- Pair the sensor with the console before mounting to confirm signal strength
- Clear the funnel and internal channel at the start of each rainy season
FT009TR Rain Gauge Sensor Questions
What is the real range between the sensor and the console
100m in open air. Through walls, foliage and a roof, plan for around 30m, which covers a typical house and garden.
How often does it update
Every 60 seconds, which provides a balance between data freshness and battery life.
Does it have a solar panel
No. It is powered by four AAA alkaline cells only. There is no solar assist.
Can it work with a console we already sell
If that console is on the UCTECH 433MHz protocol, yes. Send us the model and we will confirm before you order.
What is the lead time and minimum order
Tell us the quantity and target ship date and we will confirm both by email. Lead time depends on whether own-label printing and packaging are involved.
Which certifications does it carry
TBC. Ask us for the current certificate set for your destination market before you place the order.
