Temperature logger ideal for food safety, biological, medical and pharmaceutical monitoring

Mouser is now stocking the DS1925 iButton temperature logger from Maxim Integrated. The temperature logger is a rugged, self-sufficient system that measures temperature and records the result in a protected memory section at a programmable rate. The system is ideal for logging temperatures in food safety, biological sciences, and medical and pharmaceutical product monitoring. The logger provides longer monitoring sessions compared to other data-logging products, while maintaining the desired sample rate. Designers can store a total of 122KBbytes of 8-bit readings or 61Kbytes of 16bit readings taken at equidistant intervals ranging from five minutes to 273 hours. Additionally, the device offers 512 bytes of nonvolatile memory for storing application-specific information. It 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. Designers can program the device to begin collecting data immediately, after a delay, or after a temperature alarm. The device delivers high accuracy (±0.5C) over a wide temperature range of -40C to +85C. The device can measure battery life and retains measurements even if the battery life ends before the logger is replaced. Every device is factory-lasered with a guaranteed unique 64-bit registration number that allows for absolute traceability. The durable stainless-steel 17.35mm × 5.89mm package is highly resistant to environmental hazards such as dirt, moisture, and shock.
