DS1921G/DS1923 Temperature/Humidity Logger Kit:
This kit contains the following items:
K-CLIP®: A reusable and uniquely formed stainless steel spring temper K-CLIP®. The K-CLIP® instantly attaches, with finger tip application, to any style line of fencing commonly used to contain livestock or wildlife. The constant force of the spring tension by the K-CLIP® provides excellent slip resistance on smooth wire up to 1/8" diameter and cordage diameters to 5/16". In the "clipped-on-self" mode, the K-CLIP® provides attachment to larger diameter objects such as tree limbs and piping. In the "clip-on-object" mode, the K-CLIP® provides attachment to objects such as sheet metal.
iButton FOB: A uniquely formed plastic snap-in fob offering the simplest way to mount an iButton® for applications that require only momentary contact. The fob can be attached to objects using items such as the reusable K-CLIP®. Do not apply solvents or adhesives to this fob. This might affect the mechanical strength and reliability. This fob is now the DS9093AY+ yellow snap-in fob.
DS1921G iButton Thermochron Sensor: A complete self contained temperature data logger measuring only 17.35mm wide and 5.89mm thick. It has an accuracy of +/- 1°C from -30°C to +70°C. A built in real-time clock and timer has accuracy of +/- 2 minutes per month. The logger automatically wakes up and measures temperature as user-programmable intervals from 1 to 255 minutes. Logs up to 2048 consecutive temperature measurements are recorded in protected nonvolatile random access memory. A long-term temperature histogram is also recorded with a 2.0°C resolution. There are programmable temperature-high and temperature-low alarm trip points available. The device records 24 time stamps and durations when temperature leaves the range specified by the trip points. 512 bytes of general purpose read/write nonvolatile randam access memory is available for user programming of various information such as placement location information.
DS1923G Hygrochron Sensor: A complete self contained temperature/humidity logger 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 userdefined delay or after a temperature alarm. Access to the memory and control functions can be passwordprotected. 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.
POLY TAG: A HDPE Polyethalene UV stabilized plastic tag for indoor and outdoor use. It contains 2 reinforced extra thick hanging holes. It has a permanent molded 90° bend for providing movement in wind for excellent visibility. It can provide thermal draft blocking protection when used with the Thermochron sensor.
DS1402D-DR8 Blue Dot Receptor: Provides easy connect interfacing to PC via a 1-wire to PC interface such as the DS9097E. It has solder points on the solder side so you can hardwire other 1-wire networked devices.
DS9097E Serial Interface: A RJ-11/12 1-wire to PC DB-9 serial port interface.
IBM compatible personal computer (PC) with 1 serial port (can be used with some USB to serial converters)
Windows 98,ME,2000,XP operating system
Softwares Included on CD-ROM:
This program can be used to setup a temperature logging session in the DS1921. The recorded data can be downloaded and exported to other file formats using this program. More functional information is included in the program.
This program can be used to log 1-Wire temperature sensors with a PC. Text log files can be generated along with web pages including graphs. More functional information is included in the program.
In the plots below, the yellow line is the Logic Controlled Technology lab temperature and the blue line is the building attic temperature. These are being recorded using the interface in the kit and 2 not included DS1920 sensors. We will be selling a DS1920 sensor module soon.
These are the drivers needed to use the serial interface and other programs with the kit.
This program is needed to view and print the included datasheets on the CD-ROM.
