Abstract
A physical variable sensor with a processor circuit that can be used for any of a number of different applications. The variable sensor is compact and inexpensive to produce. The variable sensor comprises first, second and third substrates. On the second substrate is mounted a sensor component and a first processor circuit to convert the output of the sensor component to a standard electrical signal. A second processor circuit is provided on the third substrate. The second processor circuit includes an amplifier circuit, a digital fuzzy microprocessor and a luminous element to transmit an optical signal to the exterior. A solar cell can be provided on the first substrate to supply energy to the circuits. The first and third substrates are common to all types of sensors, and by modifying the second substrate different sensors to measure different types of variables can be produced.
