FT0374 WiFi PM2.5 Weather Station
The FT0374 WiFi PM2.5 Weather Station is a complete indoor console and integrated outdoor sensor system that measures temperature, humidity, wind speed and direction, rainfall, barometric pressure, UV and sunlight levels, and PM2.5 air quality. It transmits data every 16 seconds
What This Model Is For
The FT0374 WiFi PM2.5 Weather Station is a complete indoor console and integrated outdoor sensor system that measures temperature, humidity, wind speed and direction, rainfall, barometric pressure, UV and sunlight levels, and PM2.5 air quality. It transmits data every 16 seconds over a 433MHz link to a console that connects to a 2.4GHz Wi-Fi network, enabling real-time data upload to weather services like Weather Underground and WeatherCloud. The outdoor sensor uses solar assist to extend battery life, and the console includes alarm functions, historical min/max records, and manual calibration for all sensors.
- Integrated outdoor sensor with 433MHz transmission at 100m open range, no cabling needed
- Real-time PM2.5 monitoring with alarm at 35 μg/m³, updated every 2 seconds
- Solar assist reduces battery drain, extending life in sunny conditions
- Wi-Fi upload to Weather Underground and WeatherCloud for public data sharing
- Manual calibration for all sensors avoids drift issues in long-term use
Where It Is Used
- Urban home weather stations for residents tracking air quality and local weather
- Schools and community centres displaying real-time environmental data
- Horticultural greenhouses needing PM2.5 and humidity monitoring
- Retail chains selling own-label weather stations with environmental alerts
- Cold chain or warehouse monitoring where humidity and temperature trends matter
Who It Is For
- Consumer electronics brands launching an own-label weather station with air quality data
- Distributors replacing a sensor that failed after one season due to battery drain
- Agricultural integrators monitoring outdoor air quality and microclimate
- Building services teams needing a battery-powered sensor without trenching
- Hospitals or care homes tracking indoor and outdoor environmental conditions
Problems It Solves
- Sensors that fail after one winter due to battery depletion in outdoor units
- Air quality monitoring that updates only every 10 minutes, missing real-time changes
- Wi-Fi-only sensors that drop out when the router is unreachable
- Console systems that cannot be calibrated after installation, leading to drift
- Lack of public data sharing capability in basic weather stations
Technical Features
- Integrated outdoor sensor with 433MHz transmission every 16 seconds
- PM2.5 sensor updates every 2 seconds with accuracy ±10 μg/m³
- Solar panel acts as auxiliary power, not a battery charger
- Console supports 2.4GHz Wi-Fi and uploads data to Weather Underground and WeatherCloud
- Manual calibration available for temperature, humidity, pressure, wind, rainfall, sunlight, and PM2.5
- Outdoor sensor includes low power indicator for battery status
- Console supports wall mounting or desk freestanding use
- Displays wind speed in m/s, km/h, mph, knots, and Bft; direction as icon and numeric
- Barometric pressure in hPa, mmHg, or inHg with absolute or relative mode
- Rainfall data shows rate, 24-hour, weekly, monthly, and total accumulation

Materials and Construction
- Moulded plastic housing for the outdoor sensor
- Integrated solar panel on the sensor body
- Weather sealed battery compartment sized for 4 x AAA cells
How It Is Made
Outdoor sensor sub-assemblies are populated and soldered on our own assembly line
Housings are sealed and checked 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 outdoor sensor
- Constant temperature and humidity chamber runs covering the -40 to +60 degrees C range
- Vibration testing to simulate transport and mast loading
- Smog ageing to verify housing and seal integrity
- 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 and solar configurations on request
- Manual and quick start guide in the destination language
Compared With the Alternatives
vs Separate indoor console and outdoor sensor with no Wi-Fi
No public data sharing, but lower cost and simpler setup
vs LoRa-based weather stations
433MHz is cheaper and sufficient for a single property; LoRa is better for multi-site or long-range coverage
vs Battery-only sensors without solar assist
Solar assist extends battery life, especially in sunny climates, reducing maintenance
Use Guide
- Mount the outdoor sensor clear of obstructions, ideally 2m above ground
- Align the sensor’s direction mark to true north before securing the mast
- Use lithium cells for sites that drop below freezing
- Pair the sensor with the console before mounting it outdoors
- Check the cup bearing and clear debris at the start of each season
FT0374 WiFi PM2.5 Weather Station Questions
What is the real range between the sensor and the console
100m in open air. Through walls, foliage, or a roof, plan for around 30m, which covers a typical house and garden.
How often does the PM2.5 sensor update
Every 2 seconds, which allows for real-time tracking of air quality changes.
Does the solar panel charge the batteries
No. The panel supplies power during daylight and reduces the load on the AAA cells, extending battery life but not charging them.
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.
