SMART AUTO CALIBRATOR

Smart Auto calibrator is a microcontroller based digital device intended to perform calibration of sensor. Arduino micro controller along with LabVIEW software allows on-site calibration of sensors in automatic manner .This not only save the money and time but makes the system very effective by minimizing the sensing error. This paper discusses the implementation of software technique on comparing the output from the master sensor with the test sensor. Controller compares the value and performs the calibration in a periodic manner with the duration set by the user.
