Study sensor signal noise and apply proper hardware techniques to reduce it to acceptable levels. In module 1 you will learn how to specify and use temperature sensors in an embedded circuit. First, ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.

It’s just a simple sensor for detecting ground vibrations, whether they be due to passing trucks or The Big One. [Alex] lives in California, wedged between the Hayward, Calaveras, and San ...
