The DS1922L temperature logger iButton® is a rugged, self-sufficient system that measures temperature and records the result in a protected memory section. The recording is done at a userdefined 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 applicationspecific 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 DS1922L 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 DS1922L 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 DS1922L to be mounted on almost any object, including containers, pallets, and bags.

Application
The DS1922L is an ideal device to monitor for extended periods of time the temperature of any object it is attached to or shipped with, such as fresh produce, medical drugs and supplies and for use in refrigerators and freezers.

Note that the initial sealing level of DS1922L achieves the equivalent of IP56. Aging and use conditions can degrade the integrity of the seal over time, so for applications with significant exposure to liquids, sprays, or other similar environments, it is recommended to place the Thermochron in the DS9107 iButton capsule.
