Aiming at the problem of the traditional strain-electric testing method which is widely used in the testing of oil derrick.A wireless strain sensor is designed to test the structure of oil derrick and take CC1110 wireless microcontroller to be the core component.The introduction of the wireless strain sensor’s composition

hardware circuit and software design has been shown.The experiment and calibration about the wireless strain sensor proves that it has the advantages of high measurement precision

small size

low power consumption

reliable transmission

high anti-interference ability and be suitable in the field of testing practice.
