Audio Bio Harmonic With Wt5001 Smartchipusing Solar Cell

Abstract

The design of audio bio harmonic (ABH) with smart-chip WT5001 using solar cell technology in the form of ABH instrumentation with an electricity resource derived from solar energy has been successfully created and tested, which includes (i) testing the peak frequency of sound and sound output, and (ii) emptying and charging tests to determine the effectiveness of the use of the solar cell as the power provider. The ABH system consists of (i) a sound generator device composed of WT5001 sound modules, amplifiers, and horn speakers, and (ii) structured power supply devices for solar cell modules, charge controllers, and batteries for storing power. The test results of the peak frequency for the insect (garengpung) sound files and the output sound of the ABH device indicate a deviation of the peak frequency of 13.46 Hz to 140.81 Hz. The 15 hours emptying test results in on mode with battery charging for 7 hours shows that the use of 10Wp solar cell is effective to provide electrical power in ABH tool operation.

Design and Manufacturing Audio Bioharmonic Technology with Manipulate Peak Frequencies for Crop Field

“…Table 1 shows very small deviations between source sound of mp3 files and output sound of ABH devices ranging from 259, 140, and 172 Hz. This deviation occurs because there are several factors such as the time-domain that is not the same at the time of measurement and the occurrence of errors in the speaker [9].…”

“…Many ABH devices have been created, one of them is using WT5001. ABH design with WT5001 smart chip provides quite good with a small deviation of the measurement results of mp3 files and ABH sound output [9]. Application of ABH Device significantly increases the growth of rubber [8].…”

“…The result can stimulate the opening of stomata wider than without treatment, thereby increasing the effectiveness of the absorption of fertilizer nutrients which are very useful for plant growth [7]. This study uses a sound source from garengpung (Dundubia Manifera) which has been used by many other researchers and can increase the productivity of the crop field [7][8][9]. Besides sound waves can stimulate crop field, the sound wave may also strengthen the immune system of plants from pests and virus diseases [2].…”
