Temperature and Humidity Data Logger "iButton" Model: DS 1923

The DS1923-F5# is a high-resolution iButton® focused on applications that require humidity logging and containing a complete temperature and humidity logging system. This is a reliable, flexible, low-cost data logger with excellent battery life. The DS1923-F5# is great in applications such as food preparation and processing, transportation of sensitive goods, warehouse monitoring, and environmental studies.

The temperature range of this device is -20°C to +85°C with an accuracy range of ±0.5°C in the range of -10°C to +65°C after software correction. The humidity range is 0% to 100% relative humidity. The DS1923-F5# has a programmable resolution of 0.5°C for the 8 bit and 0.0625°C for the 11 bit. The device can read 8192 values at a logging rate of 1 second to 273 hours for the 8 bit, and the 11 bit can read 4096 values in with the same logging rate. Battery life information can be found on the DS1923-F5# data sheet.

The DS1923-F5# is calibrated against a NIST traceable source. A NIST traceable certificate for any DS1922T-F5# purchased from iButtonLink is available for download on the Maxim website. A sample certificate can be seen here. Please see the iButton® Data-Logger Calibration and NIST Certificate FAQs for more information.
