Abstract

Multiple identical data loggers are produced on sheet material and then separated to produce individual products for distribution to separate locations. A continuous roll of tape sheet material comprises a contiguous series of data loggers which each include a cover sheet, a transponder, a sensor, a power source (such as a battery), an antenna, a microprocessor, an adhesive layer and means to separate individual data logger elements from one another.

Claims

1. An article of manufacture comprising a matrix roll of continuous tape sheet material supporting thereupon a plurality of contiguous separable identical RFID data logger modules, as discreet units or segments, which each comprises a cover label on an insulation layer over a flexible printed circuit board, wherein said board also comprises a microprocessor, a power supply, a sensor and an antenna and a peel away release tape having a high temperature removable backing which upon removal exposes the segment for attachment to a surface.

2. A method of manufacture of multiple data logger units which each includes a protective layer, adhesive backing, a bar coded label and a write upon window area, which method comprises forming separate identical loggers on a matrix sheet of tape material;

separating said units from said sheet matrix as separate modules connected by radio frequency; and

thereafter fastening said units to a measurement surface as a linked array to detect and to measure temperature of said surface.

3. A system of temperature management comprising the disposition on a thermal measurement surface of an array of discreet separate multiple identical RFID data logger units connected to one another by radio frequency links and also connected to a common power source, to detect and to measure variation of temperature of said surface;

wherein each of said units comprises a temperature sensor, a power source link, an antenna and a micro processor in a flexible printed circuit board.
