    Hello,
    I am newbie here and looking for some help in circuit schematics.The idea is to measure sensors which the baseline resistance of the sensors are 100k-100MOhms and the resistance of the sensors can vary in the same distance, for example, sensor with 10MOhm baseline resistance can exhibit a change up to 90% of its baseline. The readout of the resistance should pass to a computer using Arduino/Xbee or other technology. The working voltage of the sensor is 1V.
    Any recommendations for such circuit ?

    Thanks.
