Electric Circuit Steadiness and Sensor Selectiom in the Colorimetric Experiment

Many parameters can be measured by light-electricity.The steadiness of an electric circuit and the selection of a sensor in measurement will have a direct impact on the surveying accuracy.Through trial and error,the precision was raised with less error by properly improving circuits and selecting a sensor.The article introduced the function of the circuits and the sensors,pointing out some problems and the causes in common measure,and suggesting some effective methods and steps to solve them.
