ROGADOR, JENNY LYN V., TORIO, ANNALYN G., Design and Development of Acoustic Wave Soil Moisture Meter. Undergraduate design Project. Bachelor of Science in Electronics and Communications Engineering. Cavite State University, Indang, Cavite. April 2007. Adviser: Engr. Cesar C. Carriaga. <br/>The design and development of acoustic wave soil moisture meters was conducted at Brgy. Bancod, Indang, Cavite. Its main objective is to design, develop and construct a portable soil moisture meter that uses acoustic waves in measuring the amount of soil moisture. The system is composed of two main units: the Acoustic wave source and detector. The source is the frequency acoustic source that sends acoustic waves by means of piezo electronic tweeters. <br/>The detector is comprised of Microphone pre amplifier that detects acoustic wave coming from the source unit, the Analog to Digital Converter, Micro Controller Unit and the seven segment display. The system is powered by two 9V battery. The evaluation of the design was done through monitoring of the data display of the device. The device was monitored for four days that showed a reading ranging from 98-99. Readings using the device were compared to the readings taken using commercially available moisture tester and interpreted as having no significant value for the study. <br/>The frequency of the sound wave used was 5 kHz, which is relatively high, cannot penetrate through solid objects. The higher the frequency, the shorter the wavelength, the slower a signal can penetrate through solid objects.<br/> |
