How it works
From logger to data in three steps
Place the iButton, it records on its own, then download the readings with a USB adapter and software.
Place the logger
Attach the iButton to the goods, vehicle or location you need to monitor.
It records automatically
Measures temperature or humidity and stores thousands of readings in memory.
Download the data
Connect via USB adapter and software to view, graph and export the log.
*USB adapter, cable and software required
Description
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. Accessories permit the DS1923 to be mounted on almost any object, including containers, pallets and bags.
Features
- Digital Hygrometer Measures Humidity with 8-Bit (0.6%RH) or 12-Bit (0.04%RH) Resolution
- Operating Range: -20°C to +85°C; 0 to 100%RH (see Safe Operating Range Graph in the full data sheet)
- 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°C 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 Nonvolatile (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
- Underwriters Laboratories (UL) Recognized
Specifications

- Data Logger Sample Rate1s to 273 hours
- Data Logger Accuracycorrectible to +/- 0.5’C
- Data Logger ResolutionSelectable
8-bit = 0.5’C
11-bit = 0.0625’C - Measurement Range - Temperature -20 to +85’C
- Measurement Range - Humidity0 to 100% RH
- Security Featurespassword protected
- Programmable AlarmTemperature High/Low, Humidity High/Low
- Real Time ClockYes
- Weight5g
- Sizediameter 17.35 x 5.9mm
- IP RatingIP56
- Battery Lifedepends on number of factors such as Temperature and Logging rate. E.g. 8-bit logging @ 20’C at 30 second intervals, the battery should last around 300 days. Record every 10 minutes in 8-bit mode @ 20’C, the battery should last around 5.5 years.
