1. Introduction
This manual provides essential information for the proper use and understanding of the Fonkan FT-9824 UHF RFID Passive Temperature Sensor Sticker Tags. These tags are designed for long-range temperature monitoring in various applications, particularly cold chain management, by leveraging passive UHF RFID technology. They are battery-free and rely on an external RFID reader for power and data communication.
2. Product Overview
The Fonkan FT-9824 tags are advanced UHF RFID labels equipped with integrated temperature sensing capabilities. They are fully passive, meaning they do not require an internal power source, making them ideal for long-term, maintenance-free deployment. The tags communicate temperature data to compatible UHF RFID readers within their reading range.

4. Setup
The FT-9824 temperature sensor tags are designed for ease of use. Their primary setup involves physical application and integration with a compatible UHF RFID reader system.
4.1 Tag Application
- Prepare Surface: Ensure the surface where the tag will be applied is clean, dry, and free from dust or grease for optimal adhesion.
- Apply Tag: Peel the tag from its backing and firmly press it onto the desired item or surface. Ensure there are no air bubbles.
- Placement Considerations: For best reading performance, avoid placing tags directly on metallic surfaces or in close proximity to other RFID tags without proper spacing, as this can interfere with signal integrity.
4.2 Reader System Integration
To read the temperature data from these passive tags, a compatible UHF RFID reader is required. The reader system typically involves:
- A UHF RFID reader with an antenna (e.g., 7dBi, 9dBi, 12dBi integrated readers).
- Software to interpret the EPC and temperature data from the tags.
- Appropriate communication interfaces (e.g., RS232, RS485, TCP/IP, Wiegand) to connect the reader to a host system.
Fonkan can provide compatible readers and communication protocols for development. Please contact the seller for detailed reader setup instructions and software integration guides.
5. Operating Instructions
Once the FT-9824 tags are applied and the UHF RFID reader system is set up, operating the system to read temperature data is straightforward.
- Power On Reader: Ensure your UHF RFID reader is powered on and properly connected to its antenna and host system.
- Activate Reading Mode: Start the reader's software application (e.g., "Reader1100Demo V1.85") and activate the continuous or auto-working reading mode.
- Scan Tags: Position the items with the applied FT-9824 tags within the reading range of the reader's antenna. The reading distance can vary based on the reader's power and antenna gain (e.g., 0-2m for 7dBi, 0-4m for 9dBi, 0-6m for 12dBi readers).
- Monitor Data: The reader software will display the EPC (Electronic Product Code) and the corresponding temperature data from each detected tag. The tags support reading MMVD Temperature sticker labels.

6. Maintenance
The Fonkan FT-9824 passive RFID temperature tags are designed for minimal maintenance due to their battery-free nature.
- Cleaning: If necessary, gently wipe the tag surface with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials that could damage the tag.
- Storage: Store unused tags in a cool, dry place, away from direct sunlight and extreme temperatures, to preserve adhesive quality and tag integrity.
- Physical Damage: Avoid bending, creasing, or puncturing the tags, as this can damage the internal antenna and chip, affecting performance.
7. Troubleshooting
If you encounter issues with your FT-9824 tags, consider the following troubleshooting steps:
- Tag Not Reading:
- Check Reader/Antenna: Ensure the UHF RFID reader and antenna are properly powered, connected, and functioning correctly.
- Reading Distance: Verify that the tag is within the optimal reading range of the antenna. Reading distance is dependent on the reader's power and antenna gain.
- Tag Orientation: Experiment with different tag orientations relative to the antenna.
- Interference: Check for potential sources of electromagnetic interference or metallic objects near the tag or antenna that might obstruct the signal.
- Tag Damage: Inspect the tag for any visible physical damage.
- Incorrect Temperature Readings:
- Tag Placement: Ensure the tag is applied correctly to the item being monitored and is not covered by materials that could insulate it from the actual temperature.
- Reader Calibration: If the reader system allows, verify its calibration for temperature readings.
- Environmental Factors: Consider extreme environmental conditions that might affect the tag's performance or the accuracy of the reading.
- Multiple Tags Not Reading Simultaneously:
- Tag Density: If many tags are in close proximity, ensure the reader's anti-collision algorithm is optimized.
- Reader Power: Increase reader power if possible, within regulatory limits.
8. User Tips
- Optimal Placement: For critical temperature monitoring, place the tag directly on the surface or within the environment where the most accurate temperature reading is needed.
- Batch Testing: Before large-scale deployment, test a small batch of tags with your specific reader setup to confirm compatibility and reading performance.
- Data Logging: Utilize reader software with data logging capabilities to record temperature histories for compliance and analysis in cold chain applications.
- Reader Compatibility: While these tags adhere to EPC Class 1 Gen 2 V1.2 protocol, ensure your chosen reader is specifically compatible with passive temperature sensing RFID tags for full functionality.
