Product Overview

What This Model Is For

The FT004 is a wireless thermometer that measures indoor and outdoor temperature over a 433MHz link, transmitting readings every 60 seconds to a console up to 50 meters away in open air. It uses two AAA batteries in both the console and sensor, with the option to use lithium cells for cold environments. The sensor shares a common housing family with other UCTECH outdoor sensors, allowing a brand to expand from a single temperature sensor to a full weather station without redesigning the mounting system.

  • Measures indoor and outdoor temperature with a single sensor and console pair
  • 60 second transmission interval provides timely updates without overwhelming the link
  • 50 meter range in open air covers most residential and small commercial sites
  • Lithium battery option extends life in cold climates where alkaline cells fail
  • Shared housing design allows future expansion to multi-sensor weather stations

Application Scenarios

Where It Is Used

  • Home and apartment temperature monitoring for energy efficiency and comfort
  • Greenhouse and nursery environments where outdoor temperature affects plant health
  • Small retail stores and offices needing a simple indoor-outdoor display
  • Outdoor sheds and storage units where temperature control is critical
  • Rental property management with a single display for multiple units
Buyers

Who It Is For

  • Consumer electronics brands launching a low-cost wireless thermometer under their own label
  • Distributors replacing a sensor that failed after one winter due to battery drain
  • Agricultural suppliers bundling temperature monitoring with irrigation or heating controls
  • Building services integrators adding temperature visibility without wiring
Pain Points

Problems It Solves

  • Sensors that fail in winter due to alkaline battery failure in cold temperatures
  • Long transmission intervals that miss temperature swings in real time
  • RF links that drop out beyond 20 meters, requiring a repeater or gateway
  • Separate indoor and outdoor units that do not share a common mounting system

Manufacturing

How It Is Made

Step 01

Sensor sub-assemblies are populated and soldered on our own assembly line

Step 02

Temperature sensors are calibrated during final assembly

Step 03

Housings are sealed and checked on rainfall and waterproof test equipment

Step 04

Every unit is ageing tested before it leaves the factory

Testing

Quality Control

  • Rainfall and waterproof testing on the assembled sensor
  • Constant temperature and humidity chamber runs covering the -40 to +60 degrees C claim
  • Vibration testing to reproduce transport and mounting loading
  • Smog ageing to check the housing and seals
  • Final ageing test on every unit before packing
Own Label

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
Honest Comparison

Compared With the Alternatives

vs Wired temperature sensors

No cable run needed, but range is limited to 50 meters in open air

vs Wi-Fi connected sensors

No router dependency, but 433MHz is simpler and cheaper for a single sensor

vs LoRa sensors in our FT0310 and FT0832 range

433MHz is sufficient for a single building; LoRa is needed for larger sites with multiple sensors

Installation

Use Guide

  • Place the sensor at least 1 meter away from heat sources like radiators or windows
  • Mount the console in a location with clear line of sight to the sensor
  • Use lithium batteries if the sensor will be exposed to temperatures below 0 degrees C
  • Pair the sensor with the console before mounting it outdoors
  • Check the battery level in both units at the start of each season

FT004 Wireless Thermometer Questions

What is the real range between the sensor and the console

50 meters in open air. Through walls, foliage, or a roof, expect around 20 to 30 meters, which covers most homes and small buildings.

How often does it update

Every 60 seconds, which is long enough to save battery but short enough to track temperature changes in real time.

Can I use lithium batteries in the sensor

Yes. Lithium cells are recommended for outdoor use in cold climates where alkaline batteries lose power quickly.

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.
