What This Model Is For
The FT0423 is a wireless thermo-hygrometer system that measures indoor and outdoor temperature and humidity, transmitting data every 60 seconds over a 433MHz link. The console displays readings from both the indoor unit and a remote sensor (FT017T), which is designed to operate in temperatures from -40 to +60 degrees C. The system uses two AAA batteries in the console and two in the remote sensor, with lithium cells available as an option for cold environments. It is built for use in residential, commercial and industrial settings where remote environmental monitoring is needed without wiring.
- Measures both indoor and outdoor temperature and humidity in one system
- 433MHz transmission reaches 100 meters in open air with no gateway or cabling
- 60 second update interval provides timely data without excessive battery drain
- Remote sensor operates from -40 to +60 degrees C, suitable for cold climates
- Lithium battery option available for long-term reliability in low temperatures

Where It Is Used
- Home and office environmental monitoring with a single display console
- Greenhouse and cold storage monitoring where temperature and humidity must be tracked remotely
- Retail and warehouse environments needing ambient condition tracking across multiple zones
- Outdoor weather stations where a single sensor can be placed in a protected but exposed location
- Industrial sites with equipment sensitive to humidity and temperature shifts
Who It Is For
- Consumer electronics brands launching an own-label environmental monitor
- Distributors needing a complete indoor-outdoor monitoring kit for resale
- HVAC and building services integrators adding environmental feedback to control systems
- Agricultural and horticultural suppliers bundling sensors with climate control gear
- Cold chain logistics providers monitoring storage conditions during transport
Problems It Solves
- Sensors that fail in sub-zero temperatures due to poor battery or component tolerance
- Systems that require wiring between indoor and outdoor units, increasing installation cost
- Data updates that are too slow to reflect real-time changes in temperature or humidity
- Lack of a single display that shows both indoor and outdoor readings clearly
- Remote sensors that cannot survive extended exposure to cold or high humidity
Technical Features
- Indoor temperature sensing from 0 to 60 degrees C
- Outdoor temperature sensing from -40 to +60 degrees C
- Humidity sensing from 10 to 99 percent RH
- 433MHz one-way wireless transmission with 100m open area range
- Transmission interval of 60 seconds
- Temperature accuracy of plus or minus 1 degree C
- Humidity accuracy of plus or minus 5 percent
- LCD display size of 52 x 41 mm
- Remote sensor (FT017T) compatible with the console and powered by two AAA batteries

Materials and Construction
- Moulded plastic housing for the console and remote sensor
- Weather sealed battery compartment sized for 2 x AAA cells
- Integrated LCD display with 52 x 41 mm viewing area
How It Is Made
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 sensor and console
- Constant temperature and humidity chamber runs covering the -40 to +60 degrees C range
- Vibration testing to simulate transport and site loading
- Smog ageing to verify housing and seal durability
- 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 Wired thermo-hygrometers
No cable run required, but limited by battery life and range compared to 433MHz
vs Wi-Fi based sensors
No network dependency or router needed, but 433MHz has shorter range than Wi-Fi in open air
vs LoRa sensors in the FT0310 and FT0832 range
433MHz is lower cost and sufficient for a single building; LoRa is better for multi-site or long-range deployments
Use Guide
- Place the remote sensor away from direct sunlight, heat sources and drafts
- Mount the console at eye level for easy reading, ideally near a power outlet
- Use lithium AAA batteries in the remote sensor if operating below 0 degrees C
- Pair the sensor with the console before mounting it outdoors
- Clear dust and debris from the sensor housing at least once per season
FT0423 Wireless Thermo-Hygrometer Questions
What is the real range between the sensor and the console
100 meters in open air. Through walls, glass or foliage, expect around 30 meters, which covers most homes and small buildings.
How often does it update
Every 60 seconds, which balances data freshness with battery life.
Can I use lithium batteries in the remote sensor
Yes. Lithium AAA cells are recommended for use in cold environments or where long-term reliability is needed.
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.
