Capacitive sensing as a user input medium is no longer a fringe technology relegated to select products. It is now a mature technology employed in thousands of products and millions of units.
Now that we have discussed the theory about the sigma-delta modulator, let us design a simple proximity sensor that will detect an approaching hand and switch on an LED. A 0.5 mm 2 wire, 10 cm long, ...
This chapter covers active sensing of the atmosphere using both ground-based and satellite-borne radars. Owing to the vast expanse of weather, hydrometeors, and atmospheric gases, in situ measurements ...
Active sensing encompasses the use of a transmitter and at least one receiver to measure (sense) the transmission or scattering properties of a medium at radio frequencies. In transmission ...
