船用温湿度传感器的温度特性研究
The Research of Marine Temperature and Humidity Sensor Temperature Characteristic
摘要
Abstract
According to the background noise and the temperature drift of sensor amplifier circuit are the main factors causing the measurement error of the temperature and humidity sensor,it is proposed to suppress the back⁃ground noise by setting up the filter and using the signal superposition method;the temperature characteristic of amplifier circuit is determined by data fitting technique,the temperature compensation model is established,write temperature calibration software and the temperature drift of the amplifier circuit is compensated. The experiment results show that the measurement accuracy of the temperature and humidity sensor after temperature compensation is significantly improved.关键词
