Embedded Data Systems offers a low cost handheld data collector, PIR2, well suited for asset tracking, guard tour management, or any application requiring a definitive audit trail. Each time an iButton is presented to a PIR2, the PIR2 reads and stores the iButton’s serial number along with a date/time stamp. These records are later downloaded to a Windows PC and form the basis upon which a custom audit system may be constructed.
Each PIR2 has a guaranteed unique serial number. Our SK-PIR2 development kit includes two PIR2s, which enables solutions which track multiple PIR2s to be developed. Enough iButtons are provided to allow non-trivial modeling of real world solutions. The host interface supplied is USB based; however, a serial host interface is also available. The PIR2Srv isolates the end-user software from the communication details. This means a simple configuration change is all that is needed to switch between USB and serial (there is no impact on the end-user software).
