FABISENSE PTX-02 Wireless Temperature and Humidity Sensor Buying Guide Malaysia
Content
The FABISENSE PTX-02 Temperature and Humidity Sensor combines an on-device display with 433.92 MHz wireless transmission and three selectable signal channels, according to the supplied manufacturer catalogue.
It is an option for buyers who need temperature and relative humidity readings at a selected location, with wireless monitoring subject to confirmation of a compatible receiver.
What Does the FABISENSE PTX-02 Measure?
The PTX-02 displays:
Temperature
Relative humidity
The catalogue lists a temperature measurement range of −40°C to 70°C and a humidity range of 20–99% RH.
These are measurement ranges. Confirm the permitted operating conditions, battery limitations and environmental protection before placing the sensor in unusually hot, cold or humid locations.

The catalogue marks the batteries as optional. Confirm whether batteries are included in the supplied package.
Understanding Resolution and Accuracy
The specification table lists 0.1°C and 1% RH under an “Accuracy” heading, then separately gives ±1°C and ±5% RH under “Error”.
The smaller values appear to describe display increments, but the terminology requires manufacturer confirmation.
Do not advertise the PTX-02 as having ±0.1°C temperature accuracy or ±1% RH humidity accuracy. Use the separately stated error figures when discussing the catalogue, with operating conditions subject to confirmation.
433.92 MHz Wireless Transmission
The PTX-02 uses a listed wireless frequency of 433.92 MHz.
This differs from Wi-Fi or Bluetooth connectivity. The supplied page does not list direct smartphone pairing, Tuya Smart support or internet access.
Confirm the compatible receiver before ordering for wireless use. Matching the radio frequency alone does not establish that two products can communicate.
Ask for:
Compatible receiver model numbers
Pairing instructions
Wireless transmission distance
Update interval
Maximum supported sensors
Behaviour when a signal is lost
The catalogue does not provide these details on the supplied page.
Three Signal Channels
The catalogue lists three signal channels and illustrates Channel 1, Channel 2 and Channel 3.
This may support identifying sensors within a compatible monitoring system. However, the page does not establish how many sensors a particular receiver can display simultaneously.
For monitoring several rooms, confirm the complete system configuration, including the receiver and the required quantity of PTX-02 sensors.
Applications for Homes and Offices
The FABISENSE PTX-02 may suit users who want to observe temperature and humidity in living rooms, bedrooms, offices or meeting rooms.
For example, a user can check readings at a consistent position before and after changes to air-conditioning settings or room use.
For offices in Puchong, Kuala Lumpur, Johor and Penang, a compatible wireless system may allow readings from selected locations to be viewed at a receiver. Receiver capability and coverage require confirmation.
Storage Rooms and Cabinets
Temperature and humidity readings can provide useful information when observing conditions around stored equipment, documents or other materials.
Before using the PTX-02 for a controlled storage requirement, check:
Required measurement accuracy
Permitted environmental conditions
Calibration documentation
Alarm requirements
Historical recording requirements
The supplied page does not establish data logging, export or alarm functions.
Placement for More Representative Readings
Choose a consistent location. Moving the sensor changes the conditions being measured and makes comparisons less useful.
Avoid direct sunlight and nearby heat sources. These can affect the temperature at the sensor.
Keep the sensing openings clear. Do not cover the unit or place it tightly against objects that restrict air circulation.
Allow readings to stabilise after relocation. Follow the operating manual for the recommended waiting period.
The product illustration shows a rear hanging feature. Confirm the intended mounting method and required clearances in the manual.
What to Check Before Buying
For a standalone display requirement, confirm that the screen and reading update behaviour meet your needs.
For wireless monitoring, confirm receiver compatibility, channel configuration and practical coverage.
For applications involving records or quality control, ask whether the complete system provides logging, alarms, export and suitable calibration documentation. These capabilities should not be assumed from the sensor’s wireless function.
