DS1925 - iButton High-Capacity Temperature Logger

Description

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.

Features

  • Provides High-Quality Temperature Exposure Assessment of an End Product.
  • Temperature Measurement Accuracy of ±0.5°C with Storage for Up to 125,440 Timestamped Values.
  • Flexibility to Monitor and Data-Log Long Duration Exposures with Short-Duration Time Intervals.
  • Unique Factory-Lasered 64-Bit Serial Number Ensures Absolute Traceability Because No Two Parts Are Alike.
  • Highly Configurable Options for Data Logging and Security.
  • Programmabl.

DS1925 EVALUATION KIT AVAILABLE iButton High-Capacity Temperature Logger with 122KB Data-Log Memory General Description 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.
