FT0424 Wireless Thermometer
The FT0424 is a wireless thermometer system that measures indoor temperature and humidity, plus two remote sensors for fridge and freezer environments, all linked via a 433MHz radio signal. The indoor console displays readings from all three locations, updating every 60 seconds.
What This Model Is For
The FT0424 is a wireless thermometer system that measures indoor temperature and humidity, plus two remote sensors for fridge and freezer environments, all linked via a 433MHz radio signal. The indoor console displays readings from all three locations, updating every 60 seconds. It uses standard AAA batteries in both the receiver and remote sensors, with no external power needed. The system is designed for simple integration into consumer electronics brands' own-label lines without requiring a dedicated RF or firmware team.
- Measures indoor, fridge, and freezer temperatures with one console, reducing the need for multiple devices
- 433MHz transmission reaches 50 meters in open air, covering most homes and small commercial spaces
- 60-second update interval provides timely readings without overwhelming the display
- Battery-powered sensors require no wiring, making installation quick and flexible
- Shared housing and protocol with other UCTECH sensors allow for future expansion

Where It Is Used
- Retail chains selling temperature monitoring kits for home kitchens and pantries
- Distributors replacing a wired fridge sensor that failed after one winter
- Cold chain logistics providers needing to monitor temperature in small storage units
- Home appliance brands bundling a temperature monitor with refrigerators
- Horticultural suppliers offering climate monitoring for small greenhouses
Who It Is For
- Consumer electronics brands adding temperature monitoring to an existing product line
- Distributors replacing a sensor that failed due to battery drain or RF dropouts
- Cold storage integrators who need a low-cost, battery-powered solution
- Appliance manufacturers bundling a monitor with a refrigerator or freezer
- Retail chains sourcing a ready-to-sell temperature monitoring kit
Problems It Solves
- Sensors that fail after one winter due to poor battery life or RF instability
- Wired sensors that require trenching or conduit, increasing installation cost
- Console systems that only show one temperature, forcing multiple units to be used
- RF links that fail beyond 10 meters, especially through walls and metal
- Lack of a simple, low-cost solution for monitoring both fridge and freezer
Technical Features
- Indoor temperature and humidity sensing from 0 to 60 degrees C
- Fridge and freezer temperature sensing from -40 to 60 degrees C
- Temperature accuracy of plus or minus 1 degree C across all ranges
- 433MHz one-way wireless transmission with 50 meters open area range
- 60-second transmission interval for consistent and timely updates
- LCD display size of 52 x 41 mm for clear, readable data
- Remote sensors use 2 x AAA 1.5V alkaline or lithium batteries
- Console uses 2 x AAA 1.5V alkaline batteries
- Wall mount or free-standing placement options for the console
- Sensors and console share the same UCTECH 433MHz protocol

Materials and Construction
- Moulded plastic housing for the indoor console and remote sensors
- Weather sealed battery compartment sized for 2 x AAA cells
- Integrated antenna within the sensor housing for 433MHz signal
How It Is Made
Sensor and console sub-assemblies are populated and soldered on our own assembly line
Housings are sealed and checked on rainfall and waterproof test equipment
Each unit undergoes a final ageing test before packing
Battery compartments are assembled and tested for proper fit and contact
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 mounting stress
- Smog ageing to check housing and seal durability
- Final ageing test on every unit before packing
Customisation Options
- Own-label printing and retail packaging on request
- 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 Separate indoor and fridge sensors with different protocols
One console reduces complexity and cost, but you cannot mix brands if the protocol differs
vs Wired temperature sensors
No cable run needed, but range is limited to 50 meters in open air
vs LoRa-based sensors
433MHz is cheaper and sufficient for a single home; LoRa is better for large sites with multiple sensors
Use Guide
- Place the indoor console in a central location, away from direct sunlight and heat sources
- Mount the fridge sensor inside the refrigerator, away from the cooling vent
- Place the freezer sensor on a shelf, not touching the wall or ice
- Use lithium batteries in the remote sensors if the environment drops below freezing
- Pair the sensors with the console before mounting them in their final location
FT0424 Wireless Thermometer Questions
What is the real range between the sensor and the console
50 meters in open air. Through walls and metal, expect around 15 to 20 meters, which covers most homes and small commercial spaces.
How often does it update
Every 60 seconds, which is frequent enough to track temperature changes without overwhelming the display.
Can I use lithium batteries in the sensors
Yes. Lithium batteries are recommended for cold environments or long-term use, especially in freezers.
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.
