What This Model Is For
The FT0073 is a wireless thermo-hygrometer system with a console that receives data from up to three outdoor sensors over a 433MHz link. It displays indoor and outdoor temperature and humidity, records min and max values, and alerts on high or low thresholds. The system supports both Celsius and Fahrenheit, and the console can be placed freely or mounted on a wall. Each sensor runs on two AAA batteries and transmits every 60 seconds, making it suitable for monitoring multiple zones in a home, greenhouse, or small building without wiring.
- Up to three outdoor sensors can be paired to one console, reducing the need for multiple displays
- 60 second transmission interval ensures readings stay current without excessive battery use
- 433MHz link reaches 100 meters in open air, covering most residential and small commercial sites
- Manual calibration for temperature and humidity allows fine-tuning to match local conditions
- Min and max history helps track long-term trends in temperature and humidity

Where It Is Used
- Home monitoring where indoor and outdoor conditions affect comfort and energy use
- Greenhouse or nursery setups needing humidity and temperature tracking across multiple zones
- Small office or server room environments where temperature and humidity must stay within limits
- Retail display areas where environmental conditions affect product quality
- Agricultural sheds or storage rooms where moisture levels impact stored goods
Who It Is For
- Consumer electronics brands launching a multi-sensor environmental monitor under their own label
- Distributors offering a low-cost, easy-to-install environmental monitoring kit
- Horticultural suppliers bundling sensors with climate control systems
- Building services integrators adding environmental data to a monitored space
- Home automation developers needing a battery-powered sensor with a known RF profile
Problems It Solves
- Sensors that require a wired connection and limit placement to near the console
- Systems that only show one temperature or humidity reading, missing variation across zones
- Console displays that do not support alarms or min/max tracking, requiring manual logging
- Battery-powered sensors that die within months due to frequent transmissions
- Inconsistent readings between indoor and outdoor sensors due to uncalibrated sensors
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
- Supports up to three outdoor sensors on one console
- Min and max temperature and humidity recording with automatic reset
- Manual calibration for temperature and humidity on both indoor and outdoor sensors
- Trend indicators for temperature and humidity on the console display
- Humidity comfort level display to help interpret readings
- Alarms for high and low temperature and humidity on both indoor and outdoor sensors
- 433MHz wireless transmission with 60 second update interval

Materials and Construction
- Moulded plastic housing for the console and sensor units
- Weather sealed outdoor enclosure for the sensor body
- Battery compartment sized for 2 x AAA cells in the remote sensor
How It Is Made
Sensor and console sub-assemblies are populated and soldered on our own assembly line
Each sensor is tested for correct transmission frequency and interval
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 housing
- 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 integrity
- Final ageing test on every unit before packing
Customisation Options
- Own-label printing and retail packaging on request
- Console firmware configured to match a customer's existing protocol
- Alternative battery types (lithium) available in sensor units
- Manual and quick start guide in the destination language
Compared With the Alternatives
vs Wired temperature and humidity sensors
No cable run needed, but the battery-powered sensor has a limited lifespan compared to a wired unit
vs Wi-Fi connected sensors
No router dependency and lower power use, but requires a dedicated console instead of app access
vs Single-sensor wireless systems
Supports up to three sensors, reducing the number of consoles needed for multi-zone monitoring
Use Guide
- Place the console in a central indoor location, away from direct sunlight and heat sources
- Position each outdoor sensor at least 1 meter above ground and clear of obstructions
- Use lithium batteries in sensors if operating in temperatures below 0 degrees C
- Calibrate the sensor if readings drift from known reference points
- Check battery levels in both console and sensors every 6 months
FT0073 Wireless Thermo-Hygrometer Questions
What is the real range between the sensor and the console
100 meters in open air. Through walls, foliage, or a roof, expect around 30 to 50 meters depending on building materials.
How often does it update
Every 60 seconds, which balances battery life with timely data.
Can I use lithium batteries in the sensor
Yes. Two AAA lithium cells are supported and recommended for cold climates or long-term use.
How many sensors can one console support
Up to three outdoor sensors can be paired to one console.
Can I calibrate the temperature and humidity readings
Yes. Manual calibration is available for both indoor and outdoor sensors.
What certifications does it carry
TBC. Ask us for the current certificate set for your destination market before you place the order.
