Course Structure & Syllabus

For details of standard term assessment timelines and exam structures, visit our Academics page.

Module 1

Temperature sensor based on (a) Resistive Temperature Detector (RTD), and (b) Thermistor.

Module 2

Linearization of Thermistor output, using (a) electronic circuit and (b) using a suitable algorithm

Module 3

Photoplethysmography (PPG): Obtain the PPG waveform at the red wavelength using a suitable optical source and detector, and electronic circuit. Digitize the signal using a microcontroller and transfer it to a PC using RS232/Bluetooth.

Module 4

In the PPG experiment, (a) Introduce a feedback mechanism to normalize the DC component of the signal across the users. (b) Write a program to filter the PPG wave to reduce the noise, estimate the heart rate (HR), and display it. Compare the HR with manual counting.
