DS1990A - The most popular iButton (by volume). It provides a guarenteed unique serial number at a very affordable price.
DS1990R - provides a guarenteed unique serial number. In applications where a presence pulse on contact is critical the DS1990R should be preferred over the
The Memory iButtons are available with a number of types of Memory:
EEPROM - This memory can be written and rewritten many times. However, they do have a lower write cycle limit (and price tag typically) than NV RAM.
EPROM - This memory can be written once and read many times. It is ideal for applications were the data needs to be written permanently. To program EPROM memory, a higher programming voltage (12V) is required than most 1-
Wire adapters provide. We suggest using the DS9097U-E25# programming/writing to the EPROM Memory.
NV RAM - This memory can be rewritten to millions of times. They are ideal for applications requiring the memory to be constantly accessed and modified.
DS1921G-F5# - rugged temperature logger with ±1.0°C accuracy. The recording is done at a user-defined rate, as both a direct storage of temperature values and in the form of a histogram. Up to 2048 temperature values are taken and stored at equidistant intervals ranging from 1 to 255 minutes.
DS1921H-F5# - temperature logger with ±1.0°C accuracy and an operating range is 15°C to 46°C. This unit offers higher resolution (0.125°C) than the DS1921G model over a restricted temperature range. It makes the economical choice for applications which remain withing the operating range.
DS1921Z-F5# - temperature logger with ±1.0°C accuracy and an operating range of -5°C to 26°C. It offers a higher resolution (0.125°) than the DS1921G. This makes the DS1921Z preferrable in applications that will remain within th -5°C to 26°C operating range.
DS1922E-F5# - high temperature logger is designed to provide data logging in applications up to 140°C. When housed in the DS9107+ iButton capsule, it is capable of confirming autoclave performance.
DS1922L-F5# - this temperature logger covers the same wide general purpose temperature range of -40°C to 85°C as the DS1921G does, but it provides superior accuracy (±0.5°C), resolution (Up to 0.0625°C), and capacity (up to 8192 readings).
DS1922T-F5# - high temperature logger which monitors temperature from above boiling down to freezing (0°C to 125°C).
DS1923-F5# - this temperature and humidity logger has all the features of the DS1922L with humidity logging and a -20°C to 85°C operating range.
DS1920-F5+ - this iButton Thermometer covers a wide general purpose temperature range of -55°C to 100°C, but it does not provides any logging capacity. For applications requiring standalone logging, go to our Thermochron Data Loggers.
iButton Accessories are a suite of products which enable the iButtons to read, written to, and deployeed in wide variety of applications. The accessories fall into a number of general categories:
DS1404+ - This provides a dedicated location to hang the iButton Probe of the DS1402-RP3+, DS1402-RP8+, and DS1402-RPL when they are not in use. The DS1404 comes with double-sided adhesive tape which makes the installation simple. Merely, prepare a clean and dry surface then peal and stick.
DS9093A+ - This angled iButton key ring mount, available in multiple colors, supports F5 microcan iButtons. The fob securely holds the iButton which cannot be removed without damaging the fob.
IB-FOB - This lower cost DS9093A equivalent is available in multiple colors and supports F5 microcan iButtons. The fob securely holds the iButton which cannot be removed without damaging the fob.
DS9093F+ - allows for easy snap-in and removal of the iButtons. This key ring mount supports both the F5 & F3 microcan iButtons.
DS9093N+ - this angled fob provides a temporary hold to the iButtons which may be made permanent with the use of the DS9093RA+ (below). It also leaves the back of the iButton exposed while connected to the DS9093N+ allowing the iButton to read when inserted into a DS9094F+.
DS9093RA - This stainless steel lock ring allows for the mounting of an iButton onto a DS9093N+ permanently or onto items with a pre-punched hole. It is commonly used as a plastic card mount in conjunction with the DS9093RB+.
DS9093RB+ - This stainless steel washer when used in conjuction with the DS9093RA+ provides additional retention of the F5 microcan iButtons.
DS9093S+ - iButton mount's 2-hole design is perfect for permanently mounting iButtons onto walls and other flat objects using screws or rivets.
DS9096P+ - This small, low cost, double-sided adhesive pad offers excellent retention for use in exterior and interior based applications. It is cut to the exact diameter of the iButtons.
DS9098P+ - This iButton retainer is designed to secure an iButton F5 microcan onto a PCB board. It's three metal piece design allows for proper connection for two ground and a data connection.
DS9107+ - This iButton Capsule is designed to provide waterproof (IP68) protection to a Thermochron secured within it.
1-Wire Viewer - Designed to support all iButton models. It takes a more generic approach to memory & iButton management compared to software options dedicated to the Thermochron iButtons. It serves as the entry level software which is great for managing small numbers of Thermochrons.
Thermodata Viewer - 1-Wire Light Sensor which Provides an intuitive user interface (UI) which simplifies the management of larger quantities of Thermochron loggers. This is accomplished through simplifying the download & exporting process.
Thermochron Server - This Thermochron monitoring system is designed to optimize core functions of the iButton Thermochrons and Hygrochron. It enables the Thermochron and Hygrochrons to be configured and the data analyzed using standard web browsers which allows smartphones, tablets, Windows PC, Macs, and Linux computers to access the data without specialized software. It can also be configured to push data via FTP or HTTP POST.
DS9092+ - creates the necessary electrical contact with an iButton required for reading and writing to the iButtons. It features no moving parts for improve durability and is easily installed using a push nut.
DS9092L+ - Makes the necessary electrical contacts to the iButton. It features LED for visual confirmation and it is held in location using a threaded nut.
DS9092R+ - The iButtons port will make the electrical connection to DS1402 iButton Reader Cables. It can be used in applications where the actual iButton or 1-Wire device is not accessible to the reader cable.
DS9092T# - Provides a reliable electrical connection for reading/writing to iBut. It is ideal in applications where the iButtons will only be temporarily connected to the reader.
OR-DS9107+ - This is a replacement O-Ring for a worn or damaged O-Ring in the DS9107+.
