Abstract A circuit detection system which can be used for large-scale multi-purpose temperature measurement to realize the calibration of 90 channels temperature sensor is designed. RS-232 serial communication standard is adopted in the system, the temperature data are collected on the spot by the lower computer (single chip microcomputer), collects three groups of temperature every three seconds, realizes the automatic verification of temperature, and compares with the standard thermometer through the serial port, calculates and distinguishes the temperature data automatically. Grid sensor, and automatically generate verification certificates and verification results notice. Through software design and hardware connection, the calibration of regional automatic weather station temperature sensor is realized.

Key words： metrology temperature sensor standard thermometer verification
