Abstract
A method for determining a value of an environment variable using raw data from an energetically essentially passive remote-access apparatus. A value of a first measurable quantity indicative of the environment variable is obtained from the raw data. The value of the environment variable is determined using calibration data and the value of the first measurable quantity. The accuracy is enhanced by measuring the value of the measurable quantity with a measuring signal of which strength is regulated or by obtaining a value of a second measurable quantity. The second measurable quantity is indicative of the environment variable or measurement conditions of the first measurable quantity. A method for forming calibration data for the measurements. RFID reader devices arranged to carry out the methods and energetically essentially passive remote-access apparatuses for the methods. A database that may be used with the method and a computer product including the database.
