RFID-TP was designed for long-term temperature recording, this device use a SD Card for a mass storage media which could store 134M points ( 4 Giga Byte for a file ) of temperature continually if power is always support like use a USB power adaptor plugged, but if not, optionally could use a onetime battery case or recharged battery power bank which could support about one week to one month’s recording base on one record per one second and variety battery. the duty depend on record period, period could be configured from 1 second to 12 hour for one record, recording data are easily be read out from USB port just like a USB disk, data stored on a file called “RECORD.TXT”, which is auto-generated and could be open by Notepad or Excel directly, simple and straightforward. User could copy, rename, delete it and reuse the SD Card for one thousand times.
This device has implement a real time clock which could support time-stamp function, meanwhile it use a golden capacitor to backup clock not stop if main battery or power not plug in, but only one day, so please keep in mind, after synchronize the clock, remember to plug it into main power in one day, otherwise, need to re-synchronize the clock again.
