The iButton® temperature logger (DS1925) is a rugged, self-sufficient system that measures temperature and records the result in a protected memory section. The recording is done at a user-defined rate. A total of 122K 8-bit readings or 61K 16-bit readings taken at equidistant intervals ranging from 5min to 273hrs can be stored. In addition, there are 512 bytes of nonvolatile memory for storing application-specific information. A mission to collect data can be programmed to begin immediately, after a user-defined delay, or after a temperature alarm. Access to the memory and control functions can be password protected. The DS1925 is configured and communicates with a host computing device through the serial 1-Wire® protocol, which requires only a single data lead and a ground return. Every DS1925 is factory-lasered with a guaranteed unique 64-bit registration number that allows for absolute traceability. The durable stainless-steel package is highly resistant to environmental hazards such as dirt, moisture, and shock. Accessories permit the DS1925 to be mounted on almost any object, including containers, pallets, and bags.

Applications:

  • Environmental and thermal management systems (HVAC).
  • Human and animal temperature monitoring.
  • Bio Science
  • Monitoring of refrigeration systems.
  • Temperature-critical product shipping and storage, such as fresh produce, pharmaceuticals, and blood products.
