About This Course
The capacitance to digital converter (CDC) are being extensively used in Biomedical diagnostics, Water and level sensing applications in Industrial sector, MEMS sensor interface and plenty of hobby projects by young engineers. Sensor Interface Circuits (SIC) are being built using discrete components and as integrated circuits. The knowledge of the course will help you build the interface circuits to be used with Arduino Uno, Raspberry Pi and Beagle boards too. In this course, you will learn about the following:
1. What is a sensor ?
2. How to design and build a capacitance sensor ?
3. Use a MEMS capacitance sensor in an application.
4. Interfacing an ADC to the sensor and reading out the values.
