4. INTRODUCTION
 Irrigation is the key to a successful garden.
 Long gone are the days of manual watering
or relying on a friend to water when you
are on vacation or away on business. Op-
amp is configured here as a comparator.
 Two stiff copper wires are inserted in the
soil to sense the weather the soil is wet or
dry .

17. CONCLUSION
 The circuit is more effective indoors if one
intends to use it for long periods.
 This is because the water from reservoir
(bucket, etc.) evaporates rapidly if it is kept in
the open.
 For regulating the flow of water, either a tap can
be used or one end of a rubber pipe can be
blocked using M-seal compound, with holes
punctured along its length to water several
plants.
