The Development of Solar Aerator Controlled by Wireless Signal
Keywords:
aerator, solar energy, wireless signal, dissolved OxygenAbstract
This research presents the study and construction of solar aerators that can control motor speed by a wireless signal. The proposed machine used solar panels with 570 watts to generate electricity and collected electric energy with 130 AH battery capacity. The 250 watts DC motor was used to rotate the turbine which could be used with 6 or 8 propeller turbines. The experimental results showed that the constructed machine could be controlled by a wireless signal at the distance less than 100 meters. Furthermore, the comparison between the used current, motor speed and the amount of added oxygen in the water of the aerator had been presented. The results showed that under the same testing conditions, the 6 propeller turbines used a smaller amount of current to drive the motor to spin at a higher speed than the aerator that used the 8 propeller turbine. As a result, a 6 propeller turbine can be used to increase the amount of oxygen in the water more efficiently than an 8-propeller turbine.
