MICROCONTROLLER BASED TEMPERATURE DATA LOGGER WITH SD CARD STORAGE

Temperature is basically the measurement of how hot
or cold something is, and it is one of the
fundamental entities in any kind of process control.
Temperature is also a measure of the average kinetic
energy of particles in a system. Adding heat to a
system increases the kinetic energy of its particles
and hence an increase in the temperature of the
system. Temperature is easily measured using a
thermometer. Nowadays, thermometers come in all
shapes and sizes. In computer based automated
process control applications where it may be
required to control the temperature of a plant, it
is necessary to interface the thermometer to the
computer. This is usually done either by using
analog temperature sensor devices such as
thermistors, thermocouples, RTD devices etc. and
then converting the outputs into digital format
using A/D converters, or digital sensors, such as
semiconductor sensor chips are used with direct
interface to the computer. This book is about the
design of a microcontroller based multichannel
temperature logging device with SD card storage.
