Research and Design of a Measuring System Based on Planar Capacitance Sensor for the Remainin Amount of Liquid Medicine
This paper introduces a non-contact measuring system of liquid residue based on planar capacitance sensor.The residual amount of liquid medicine is determined by measuring the change of the sensor capacity.Using the I2C communication protocol,the signal is transmitted to the display circuit and displayed in digital form.The re-sults show that the system has the characteristics of non-contact,fast,accurate and low cost,and is suitable for medical and health fields.
