Jesus G. Dayrit The study was conducted at a semi-indoor facility in Arayat, Pampanga from November 19, 2019 to March 31, 2020. It is to design, fabncate and evaluate the speed of transfer and the credibility of data of an automated monitomng system for fish incubator. The automated system runs with the logic wntten in the Arduino device and triggers stabilizers when the critical values were attained. The system informs in an hourly basis using SMS sent to the phone. Speed of transfer and the accuracy of its data were obtained to produce evaluation of the system. The code used m the systcm was C language and 1s intcgrated with devices that supports Arduimo. The payback penod of the automated system was 0.64 ycar or 7.68 months. Its breakeven puint was calculated to be 0.17 ycar or 2.05 months. The initial cost of the sysicm and its annual net income were P}7, 437.00 and P12, 452.26 respectively.
