Abstract
A tag includes an integrated circuit thereon, including memory, antenna means for RF transmission of data acquired by the integrated circuit, a sensor sensing environmental conditions to which the sensor is subjected, the sensor providing signals based on the environmental conditions to the integrated circuit, a thermistor device of increasing the accuracy of the tag by confining on-board calculation data to a resistance domain and leaving conversion of the data to a temperature domain for an external device once the data is retrieved from the tag's memory.
