摘要： The invention provides a temperature sensing system and method. A chain of repeated sequential communications is made between a temperature sensing device having a first controller which is clocked by a first crystal oscillator and a remote device having a second controller which is clocked by a second crystal oscillator. The environment of the remote device has a less stable temperature than the environment of the temperature sensing device. A time interval associated with the chain of repeated communications is measured and from this a clocking frequency and hence the temperature at the remote device can be derived, based on knowledge of the frequency-temperature characteristics of the second crystal oscillator.

摘要： A sensor tag (10) includes a crystal vibrator (110) and an antenna (102). The antenna (102) is composed of a radiating conductor (121) and connection conductors (122). A crystal vibrator (110) is mounted on land conductors (120) provided at an end portion of the connection conductors (122) on the opposite side to the antenna (121). The antenna (102) is formed in a shape such that an amount of shift (ΔF) of a radiation frequency of the sensor tag (10) falls within an acceptable range in accordance with a resonant frequency (Fxs) and an equivalent inductance (Lxs) of the crystal vibrator (110) and a self-resonant frequency (Fant) and an equivalent inductance (Lant) of the antenna (102).
