SPS1M001 Product Preview Battery Free Wireless Sensor Quality Control Water Intrusion Sensor www.onsemi.com ON Semiconductors family of Battery Free Wireless Sensors are UHF RFID wireless sensors which use the MagnusS2 Sensor IC and can perform moisture and proximity sensing functions in a variety of applications. These are designed for use in enclosed areas where size and accessibility is at a premium. RF TAG 166X20 MM CASE 888AH/AJ The quality control water intrusion sensor is specifically designed for the passive sensing of moisture in finished goods as a form of leak detection. The sensors can be placed in specific areas of the object and greatly simplifies the quality control test for leaks. This Battery Free ORDERING INFORMATION See detailed ordering and shipping information on page 3 of Wireless Sensor can reduce the number of missed defects and this data sheet. significantly improve the quality of manufacturing lines.

The reflected power to the reader. This makes it important to SPSM001 incorporates an integrated RF antenna allowing account for the frequency at which the sensor was read. For it to harvest energy and report back wet environments from both the wet and dry tests seen in Figure 1, the resulting a standard UHF compliant reader. The sensor includes a sensor values shifted around 5 codes over the FCC strong and easy to apply adhesive backing. frequency range of 902928 MHz. This factor must be The SPS1M001 generates sensor codes from 0 to 31. With accounted for in the reader software in order to ensure as little as one drop of water (0.05 ml) placed on the sensor reliable wet vs. dry reads. For more information on how yields a sensor value 5 codes lower than the dry test.
