Arduino Project: pH Temperature Data Logger

pH Temperature Data Logger adalah projek yang membaca pH dan suhu cecair, kemudian menyimpan setiap bacaan nya kedalam SD Card.

Data disimpan di dalam SD Card dalam file .CSV dan disimpan setiap saat. Setiap jam, file baru mengikut tarikh dan jam akan dihasilkan.

Skematiknya adalah seperti berikut.

PCB komponen layout nya adalah seperti berikut.
