An embedded system is a special purpose
computer system designed to perform one or a few
dedicated functions, often with real time
computing constraints.
It is usually embedded as part of a complete
device including hardware and mechanical parts.

AT89S52 Microcontroller:
• The AT89S52 is a low-power, high-performance CMOS 8-bit
microcontroller with 8K bytes of in-system programmable flash
memory.
• By combining a versatile 8-bit CPU with in-system
programmable flash on a monolithic chip, the Atmel AT89S52
is a powerful microcontroller which provides a highly-flexible
and cost-effective solution to many embedded control
applications.

Moisture Sensors:
• It can be also called as a
soil moisture sensor.
• Soil moisture is highly
variable. Accuracy from a
single site isn't enough to
run an experiment.

AC motor:• An electric motor uses
electrical energy to produce
mechanical energy.
• Electric motors are found in
household appliances such
as fans, refrigerators,
washing machines, pool
pumps, floor vacuums, and
fan-forced ovens.

TRAIC (BT136):
TRIAC, from Triode for Alternating
Current, is a generalized trade name for
an electronic component which can
conduct current in either direction when it is
triggered (turned on), and is formally called
bidirectional triode thyristor or bilateral
triode thyristor.
