SD Data logger schematic
Ok on the hardware side of the data logger, i leave the schematic for the version using a 4050 to do the level translation to 3.3 V used by the sd. u might noticed i have the 5 V instead of the 3.3 as analog ref, so change code accordingly ( or use 3.3 if u prefer, though the 5 V is better for the moisture sensor
Below ill also leave the cheaper version with resistors as voltage dividers.
