Passive Sensing inlays and tags from Smartrac
To provide the best possible accuracy and reliability when embedded in construction materials with diverse physical characteristics, Smartrac’s high-quality, battery-less Sensor inlays and tags are optimized for interaction with readers and software infrastructure provided by SensThys. The thin and customized transponders are equipped with Axzon’s Magnus® S3 ICs that can accurately detect and measure temperature and moisture levels in the surrounding environment. Like Smartrac’s other Sensor inlays, this solution-specific product offers cost efficiency and ease of implementation.
The sensing inlays are interrogated using SensThys’ solution to monitor and track the physical state of the product at construction sites, distribution yards and manufacturing facilities. Specialized software on the reader controls the interaction between it and the sensor tag so that an accurate moisture sensor value is obtained in a timely fashion. Key applications include tracking infrastructure components such as roofing materials, monitoring changes in products including thermal and moisture cycling, and tracking concrete pre-casts that might be in inventory, in transit, at holding facilities, or physically embedded within their final infrastructure.
Reader and algorithms from SensThys
The SensThys SensX Extreme RFID reader is ideal for the construction industry due to its physical robustness, which includes IP67 rating, key military standards testing, and a wide operating range including cold starts and thermal shock. The 33dBm reader has a sweeping array of sensors, including an accelerometer, gyroscope, barometric pressure, GPS and BLE beacon detection, that together enable situational awareness including its physical position, orientation and movement.
Communication is handled natively by internal Ethernet, Wi-Fi or Bluetooth, with an external cellular connection available. SensThys created the algorithms to rapidly compute the location, temperature and moisture of a tag embedded within an object. These algorithms are now available for use on all M-Power readers including the SensArray and the SensX Extreme. The algorithm can also be made available for incorporation into other fixed and handheld readers.
Solutions for real-world problems
“This design effort, coupled with extensive in-situ testing, resulted in an upgraded M-Power reader capability to offer customers a practical method to quickly and reliably interrogate Smartrac’s sensor tags. Our IP67 SensX Extreme reader, which uses the M-Power core, allows us to identify the tagged item and provide the location, time, temperature and moisture information of the asset,” said Jo Major, CEO of SensThys. “For example, the seamless integration of sensors enables customers to understand where and when a roof has started to leak or when a concrete foundation is fully cured.”
SensThys have also developed a one-stop-shop “kit” that enables mutual customers to explore Smartrac sensor tags with minimal financial outlay. The SensorKit-MT (Moisture/Temperature) is an easy-to-use collection of everything required to evaluate passive sensor tags. This kit is specifically designed for use with the Magnus-based inlays including Sensor DogBone™ and other Smartrac moisture and temperature sensing passive RFID tags. The kit is a very inexpensive way to start the evaluation of these tags with a plug-and-play kit that includes a SensArray combo reader/antenna, power source, cables, tags and a sensor reading application.
