"Very simply, this book is for the microprocessor/computer user who wants to use the machine to measure certain conditions, or to control external devices." "This book tells you how to go about it -- how to convert energy produced by pressure, force, position, temperature, etc., into an electrical voltage or current that your microcomputer can deal with." This was an early book on interfacing -- digital methods with analog needs -- and it is timeless in its approach. Highly recommended.
