Abstract

The study was focused on the design and fabrication of a microcomputer-based sensor which would measure the changes in the intensity of light through an image processing algorithm. The materials that were used in the fabricating the sensor were Raspberry Pi 2 Model B for data processing, Raspberry Pi camera for the sensing element, micro SD card for data storage, Wi-Fi adapter for wireless program execution and data transmission and Power bank for the rechargeable power supply unit. Three Neutral Density (ND) filters was used to simulate the change in intensity measured by the sensor. Based on the results, it was generally found that using ND filters to increase the intensity of light also increases the intensity measured by the sensor. Also, it can be concluded that the measured values are precise for the percent change in intensity as shown in the trials not having a significant difference in the means. This result suggests that the use of pesticide samples for measuring the changes in intensity can also be investigated to extend the scope of applications of the sensor for pesticide residue detection.
