Maxim Integrated DS1922L-F5 iButton Temperature Logger

The Maxim Integrated DS1922L-F5 is a highly reliable and robust iButton temperature logger designed for a wide range of temperature monitoring applications. This compact device is encapsulated in a durable stainless steel can, known as an F5 MicroCan, which provides a protective shell that is both water-resistant and able to withstand harsh environmental conditions, making it suitable for use in both indoor and outdoor settings.

The DS1922L-F5 is part of the iButton family, which is a series of microchip devices that communicate with host systems via a simple 1-Wire interface. This allows for easy integration with a variety of systems and ensures that the temperature data can be read and recorded with minimal setup. The device is capable of measuring temperatures ranging from -40°C to +85°C with an accuracy of ±0.5°C, making it an ideal choice for precise temperature monitoring tasks.

One of the key features of the DS1922L-F5 is its ability to store up to 8,192 temperature readings in its non-volatile memory. This large storage capacity, combined with user-programmable sampling rates, allows the device to record temperature data over extended periods without the need for frequent data retrieval. Users can configure the logging resolution to be either 8-bit or 11-bit, depending on the precision required for their specific application.

The device is powered by a built-in battery with a long lifespan, which ensures continuous operation and data logging even in the absence of external power. The DS1922L-F5 also includes a real-time clock (RTC) that timestamps each temperature reading, providing a detailed and accurate temperature history for analysis.

Programming and data retrieval from the DS1922L-F5 are made simple with the use of Maxim Integrated's 1-Wire software tools, which support a variety of host devices. The iButton design also allows for easy attachment to objects or locations being monitored, with accessories available for mounting the logger in a fixed position if required.

In summary, the DS1922L-F5 iButton temperature logger from Maxim Integrated is a highly versatile and dependable solution for anyone needing to track temperature with precision and ease.
