Development and Evaluation of Efficient Smart Solar Lawn Mower

Abstract

Solar powered lawn mower has offered a more convenient way of trimming the lawn due to the advancement in its technology. As the world gradually moves towards green technology, research has geared towards making solar powered mover readily available, efficient, and economical. However, few reports were available on the effect of grass types on battery voltage drop. In this paper, solar powered lawn mower was structured into phases which include, power supply phase, Arduino phase, motor phase and integration of the components. The 550-motor was sufficient to produce the required torque needed to drive the solar panel mower. The average efficiency of the solar panel was found to be 93 %. The battery voltage drop was investigated upon cutting different types of grasses to determine the rate at which power is dissipated in the solar powered lawn mower. The voltage drop of 0.34 V was recorded when cutting stubborn grass while that of soft grass was found to be 0.17 V. Rain sensor was incorporated to provide the user with a notification via Buzzer whenever raindrops are detected.
