  • Specifically designed microchip to identify temperature
  • Can be affixed or embedded into most materials
  • Passive UHF

The ReadySense Passive RFID Temperature Sensor Tag is an easy-to-use, robust tag that outperforms other traditional temperature sensing tags.

The ReadySense Pasive RFID Temperature Sensor Tags are much smaller, thinner and more flexible than battery-powered sensors, and they are more cost efficient than active wireless sensing tags. In fact, their low cost makes them useful for disposable and high-volume applications.

With the ability to access and collect quality data, ReadySense Passive RFID Temperature Sensor Tags enable users to consistently monitor temperatures and provide critical information to help make informed decisions.

Specifications Data
RFID temperature sensor tag product information
Material Polyester
Serialization Barcode and human-readable equivalent is digitally printed – providing excellent clarity and easy scanning. Code 39 is the standard symbology with a range of 2.7 to 9.4 CPI (characters per inch). Optional linear and 2D symbologies available. Although this product is primarily marketed as a bar code product, we can produce it with human-readable numbers only or unserialized.
Label Copy The label copy may include block type, stylized type, logos or other designs
Colors Standard colors include black, red, yellow, green or blue. Custom spot colors are also available at no additional charge. Due to contrast needed for the bar code scanner, all bar codes are black.
Standard Adhesive High performance adhesive
Sizes 4.1875" x 1.125"
Packaging Shipped on convenient rolls with scrap matrix removed for ease of removal. Cartons are clearly marked to indicate serial numbers of labels.
Shipment 14 business days


Chemical Test Summary
The ReadySense temperature tags were attached to a sheet of glass submerged in various chemicals. Observations were made at the following intervals: 2 hours, 24 hours, 48 hours. A Motorola handheld RFID reader as well as a handheld barcode reader were used to test the samples.

Temperature Test Summary
High-temperature resistance test: These tags were attached to a sheet of glass at raised temperatures for 15 minutes. Tags were then removed from the oven and tested for readability immediately.

Low-temperature resistance test - The tags were attached to a sheet of glass and exposed to -40°F for 24 hours. Tags were then checked for readability with an Alien ALH-9000 handheld RFID reader. All samples were readable while at temperature just prior to removal from freezer. No tag construction defects were observed and adhesive still had a strong bond while in the freezer.
