Mitigation of catastrophic impacts of exhausted pollutants from conventional based power plants canbe performedby extensively usingrenewable energy-based power plants. One of the promising renewableenergy-based power plants in already maturedtechnology is hydropower. However, large scale hydropower should belocatedon an appropriate site and is not economically effective for isolated and remote small communities. Micro-hydropower plants (MHPPs) canapplied to fulfill the power requirements of suchcommunities due to its inexpensive capital and low maintenance cost. Normally, MHPPs projects are finalized bycivil construction to powerhouse. A simple trash filter is usually located before the intake of the penstock. This simple trash filter usually causes a problem related to trash collection that blocks the water debit into the penstock intake. Thislow capacitymight cause the reduction of turbine's rotation, which in turn downgrade the voltage and frequency. Low voltage and frequency might harm consumers. In this paper,a new control mechanism based on Arduino Mega is introduced forautomatic trash removal.
