In my experience, doing some sensor systems with cheap sensors and expensive sensors, the difference is that cheap ones can be fast or accurate, while good ones can be both.
Using cheap sensors can allow you to validate your hypothesis. This can in turn help you justify the additional expense of calibrated and more precise sensors to accurately describe the relationship observed.
(You can also use spares of the cheap sensor equipment to play games and blow off steam while the experiment is running; Mario Kart anyone?
