Each of the four courses in the specialization focused on one aspect of a home project with a Raspberry Pi. This one, as the title indicates, focus on the very vital part, Sensors. This specialization is really very special as it really encompasses a wide variety of parts of the a home project. I highly recommend the whole specialization. You can take them in any order as they all go off in deep dives and different aspects of a home project. Thanks to Drew Wilson for a wonderful course and specialization.
This course on integrating sensors with your Raspberry Pi is course 3 of a Coursera Specialization and can be taken separately or as part of the specialization. Although some material and explanations from the prior two courses are used, this course largely assumes no prior experience with sensors or data processing other than ideas about your own projects and an interest in building projects with sensors.
