摘　　要：提出一种对传感器温度系数的校正新方法——采用二次方程校正法和温度补偿算法相结合的温度校正方法。该算法简单可靠、易实现。将A/D转换器的数字输出量和环境温度T都作为微控制器(MCU)的输入,经MCU处理运算后,获得准确的传感器测量值。A new compensation method for the temperature coefficient of the sensor——the correction method of quadratic equation and the algorithm for temperature compensation is put forward. The new algorithm is concise, reliable, and easily implemented. Both the digital output of analog digital （A/D） converter and the surrounding tempretaure T are sent to microprogram control unit（MCU） system. The accurate measured value can be obtained through the operation based on MCU system.
