What This Model Is For
The FT0047 is a wireless thermometer system that measures indoor and outdoor temperature across a wide range, transmitting readings every 60 seconds over a 433MHz link. The outdoor sensor operates from -40 to +60 degrees C and records min and max values, while the console displays both live and historical data. It runs on two AAA batteries in both units and can be placed freely on a desk or mounted on a wall. The system is designed for simple integration into existing weather monitoring lines without requiring a custom RF or firmware team.
- Measures outdoor temperature from -40 to +60 degrees C with ±1 degree C accuracy
- Records and displays min and max outdoor temperature values for trend tracking
- 60 second transmission interval ensures timely updates without excessive battery drain
- 433MHz link reaches 50 meters in open air, suitable for most residential and small commercial sites
- Free-standing or wall-mounted design allows flexible placement without wiring

Where It Is Used
- Home and office weather displays for users needing outdoor temperature without a wired sensor
- Greenhouse and cold storage monitoring where battery-powered sensors are preferred
- Small farm or garden setups where a wired connection is not feasible
- Retail and hospitality environments using a branded display with a remote sensor
- Building services projects requiring a low-cost temperature monitor for rooftop or wall-mounted use
Who It Is For
- Consumer electronics brands adding a wireless thermometer to an existing weather station line
- Distributors replacing a wired sensor with a battery-powered alternative
- Agricultural suppliers bundling temperature monitoring with irrigation or climate control
- HVAC integrators needing a low-cost sensor for zone temperature verification
- Cold chain logistics operators monitoring ambient conditions in small storage units
Problems It Solves
- Sensors that require a wired connection and limit placement options
- Temperature readings that lag due to long transmission intervals
- Inaccurate outdoor readings due to poor sensor calibration or narrow operating range
- Systems that fail to record min and max values, making trend analysis impossible
- Battery life that degrades quickly when sensors are left in extreme cold or heat
Technical Features
- Indoor temperature sensing from 0 to 60 degrees C
- Outdoor temperature sensing from -40 to +60 degrees C
- Temperature accuracy of ±1 degree C across the full range
- Min and max outdoor temperature recording with automatic reset
- 433MHz one-way transmission every 60 seconds
- 50 meter range in open air, with reduced performance through walls and foliage
- LCD display size of 38 x 32 mm for clear visibility
- Console and sensor both use 2 x AAA 1.5V alkaline or lithium batteries
- Free-standing or wall-mountable design for flexible installation

Materials and Construction
- Moulded plastic housing for the outdoor sensor
- Weather sealed battery compartment sized for 2 x AAA cells
- Integrated antenna within the sensor housing for 433MHz transmission
How It Is Made
Sensor and console sub-assemblies are populated and soldered on our own assembly line
Outdoor sensor housing is sealed and tested for water resistance
Each unit undergoes a final ageing test before packing
Console and sensor are paired and tested before shipment
Quality Control
- Rainfall and waterproof testing on the assembled outdoor sensor
- Constant temperature and humidity chamber runs to verify performance across -40 to +60 degrees C
- Vibration testing to simulate transport and mounting stress
- Smog ageing to assess long-term housing and seal integrity
- Final ageing test on every unit before packaging
Customisation Options
- Own-label printing and retail packaging on request
- Console display language and unit selection (Celsius or Fahrenheit) configurable
- Alternative battery configurations available upon request
- Manual and quick start guide in the destination language
Compared With the Alternatives
vs Wired temperature sensors
No cable run required, but range is limited to 50 meters in open air
vs Wi-Fi connected sensors
Lower cost and simpler setup, but lacks cloud data logging and remote access
vs LoRa-based sensors
433MHz is sufficient for a single building; LoRa is better for large sites with multiple sensors
Use Guide
- Place the outdoor sensor in a shaded, ventilated area away from direct sunlight and heat sources
- Mount the console at eye level for easy reading, or place it on a desk
- Use lithium batteries in the sensor if operating below freezing temperatures
- Pair the sensor with the console before mounting the outdoor unit
- Check battery status and clear any debris from the sensor housing every season
FT0047 Wireless Thermometer Questions
What is the real range between the sensor and the console
50 meters in open air. Through walls, glass, or foliage, expect around 20 to 30 meters, which covers most homes and small buildings.
How often does it update
Every 60 seconds, which balances battery life and data freshness for most monitoring needs.
Can I use lithium batteries in the sensor
Yes. Lithium cells are recommended for cold environments and extend battery life in extreme conditions.
Does it record min and max values
Yes. The outdoor sensor stores and displays the lowest and highest temperature recorded since last reset.
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.
