DS1923-F5#W - Hygrochron Temperature & Humidity iButton

Part Number:DS1923-F5#W


 Not for Sale
; -12

These units are no longer available. The standard DS1923-F5# are available for order.

*The DS1923-F5#W units do not meet the product specifications for the DS1923-F5# because they have up to 63K of device samples taken which could reduce the battery life (thus the price reduction).  The waiver for the DS1923-F5#W units is available in the "Downloads" tab.*

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.
