How Passive RFID Temperature tag Work

Passive RFID temperature sensors offer advantages over other types of battery-powered sensors for temperature data collection.

In this article, we look at another popular type of passive RFID sensor, the Passive RFID Temperature Sensor, to add to our series of posts on Passive Sensors and Passive Moisture Sensors.

We understand the impact of high temperatures on business processes and materials. We've been making tough RFID tags and labels that can withstand extreme heat and cold for years.

We now have new technology – passive RFID temperature sensors – to assist you in measuring temperature in new and powerful ways.
Temperature changes are being monitored.
Temperature sensing has long been used in a variety of materials and environments, particularly in warehouses, greenhouses, laboratories, factories, and other industrial settings. Traditional sensor technologies, on the other hand, face design challenges and high installation or replacement costs.

RFID passive sensor temperature tags have a significant advantage over existing temperature sensors, working in situations where active or semi-passive RFID sensors are impractical.

We're breaking new ground by deploying and sensing where existing technology can't. Our temperature-sensing tags are significantly smaller, thinner, and more flexible than battery-powered sensors, and they are significantly less expensive than active wireless sensing tags. In fact, because of their low cost, they are ideal for disposable and high-volume applications.

RFID passive sensors have additional advantages over other wireless sensing technologies. RFID passive sensors enable readers to read multiple RFID tags with a single reader, lowering infrastructure and hardware maintenance costs. RFID sensors can also transmit data with error correction codes, which aids in data accuracy.

Putting more RFID temperature sensor tags in more places will result in significantly more quality data for materials management and quality control in agriculture, healthcare, industrial, manufacturing, and new Internet of Things (IoT) markets.

Passive RFID temperature sensors detect temperature in the following ways:
Passive temperature sensors, which use the RFMicron S3 chip, detect temperature using circuit theory and the ability of temperature to change the voltage across a diode. This effect has the potential to turn a portion of the chip into a temperature sensor. Because temperature sensor tags return a simple 12-bit code based on what it detects rather than an actual unit of measurement, these values can be used to correlate the temperature of almost any object. The antenna design of the passive sensor, as well as the adjustable environmental tuning, provide a highly customizable sensing solution for almost any application.

DO RFID Group manufactures long-lasting, flexible passive temperature sensor tags that operate on standard UHF frequencies (915/868 MHz). These tags can be attached to or embedded in most materials and have a read range of 15-22 feet on average. Changes in impedance are wirelessly communicated to standard EPC Gen 2 readers and interpreted by a software application. The tags operate in a temperature range of -40°C to +85°C, covering most equipment and environments.

Applications for RFID temperature sensors
Because of their small size and low cost, passive RFID temperature tags can be used in a variety of industries, including manufacturing, retail, pharmaceutical, and industrial. Notably, passive temperature sensors lower telemetry costs by deploying a large number of sensors for real-time temperature mapping across assets and within a facility.

Data can be logged in all applications, and alarms can be set when temperatures fall outside of a predefined range. The RFID sensor tags' precision and placement on a variety of materials generates quality data on an unprecedented scale.

Passive RFID sensors monitoring mechanical plant and equipment temperatures make predictive maintenance easier in industrial and manufacturing environments. Temperature monitoring safeguards motors, bearings, and other components embedded in industrial machinery or exposed to variable electrical systems. Passive sensing can also help to improve the efficiency of cooling equipment (HVAC).

A wearable, disposable sensor tag for hospitals can travel with the patient, monitoring and recording temperature across a campus.

Passive RFID supports monitoring environmental and bulk material temperatures, as well as data center chiller and cooling monitoring, in warehousing and data centers.

RFID temperature tags can live in trucks, refrigerators, or thermal bags for cold chain applications, allowing for long-term monitoring of food and medicine. The combination of geolocation and temperature data is particularly effective in detecting deviations and proving that routes and allowed temperatures were followed.

In greenhouses and other green spaces, passive temperature sensors can be combined with passive moisture sensors to monitor and regulate a growing environment. The temperature of livestock can be monitored in order to manage breeding stock and separate sick animals from the herd.

Metalcraft provides temperature sensing that is passive.
Passive RFID temperature tags can serve existing sensor markets at much lower costs while also opening up new market opportunities – new ways to access quality-related data using large numbers of wireless, maintenance-free sensors.

Investing in passive RFID sensor tags generates significant new efficiency and competitive advantage; it will be easier to provide data that supports labs, grocery stores, factories, and other businesses. This new class of wireless sensor tag is battery-free and maintenance-free, lowering the total cost of ownership significantly.

As you consider the value of wireless sensing for your business, keep in mind that DO RFID Group has affordable, long-lasting RFID temperature tags on hand.
