The DS1923 temperature/humidity logger iButton® is a rugged, self-sufficient system that measures temperature and/or humidity and records the result in a protected memory section. The recording is done at a user-defined rate. A total of 8192 8-bit readings or 4096 16-bit readings taken at equidistant intervals ranging from 1s to 273hrs can be stored. In addition to this, there are 512 bytes of SRAM for storing application-specific information and 64 bytes for calibration data. A mission to collect data can be programmed to begin immediately, or after a user-defined delay or after a temperature alarm. Access to the memory and control functions can be password-protected.

The DS1923 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 DS1923 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.

  • Digital hygrometer measures humidity with 8-bit (0.6%RH) or 12-bit (0.04%RH) resolution
  • Operating range: -20 to +85°C; 0 to 100% RH
  • Automatically wakes up, measures temperature and/or humidity and stores values in 8KB of datalog memory in 8- or 16-bit format
  • Digital thermometer measures temperature with 8-bit (0.5°C) or 11-bit (0.0625°C) resolution
  • Temperature accuracy better than ±0.5°C from -10 to +65°C with software correction
  • Built-in humidity sensor for simultaneous temperature and humidity logging
  • Capacitive polymer humidity-sensing element
  • Hydrophobic filter protects sensor against dust, dirt, contaminants, and water droplets/condensation
  • Sampling rate from 1s up to 273hrs
  • Programmable recording start delay after elapsed time or upon a temperature alarm trip point
  • Programmable high and low trip points for temperature and humidity alarms
  • Quick access to alarmed devices through 1-wire conditional search function
  • 512 bytes of general-purpose memory plus 64 bytes of calibration memory
  • Two-level password protection of all memory and configuration registers
  • Communicates to host with a single digital signal at up to 15.4kbps at standard speed or up to 125kbps in overdrive mode using 1-wire protocol
  • Individually calibrated in a NIST-traceable chamber
  • Calibration coefficients for temperature and humidity factory programmed into non-volatile (NV) memory
  • Meets UL 913, 5th Ed., Rev. 1997-02-24; Intrinsically Safe Apparatus, Approved under Entity Concept for use in Class I, Division 1, Group A, B, C, and D Locations
