Water sprinklers are used to suppress the dust in mining field. Water sprinklers capacity used are of 28,000 and 70,000 L. These conventional water sprinklers comprise of 4 kinds of sprinkling thus the operator must choose and actuate any 1 type of sprinkling which is appropriate to suppress the dust. The traditional water sprinkler is worked physically by the operator that is operator turns on the type of sprinkling dependent on the dust seen by him. This technique does not completely suppress the dust and it’s not accurate. Furthermore, water is squandered if the dust density is according to the directions given by central pollution control board. Supportive to the above background, it is necessarily essential to actualize the water sprinkling system automatically which measures the dust density contained in mine atmosphere and likewise module will consequently actuate the sprinkling so as to suppress the dust in the environment.
