Arduino is in charge of the whole system’s operation.
This system is pre-calibrated with criteria that have
known values for various milk parameters. When
all parameters are within normal range, the Green
LED blinks. When all parameters are within normal
range, the Green LED blinks. It means that the milk
sample is fresh or pure milk that is free of toxins.
The RED LED blinks if the sample parameters
are below or above the standard values. It means
that the milk sample has been tampered with or
that it is poisonous or unfit for consumption. The
sample data can be accessed by a mobile device
via the Bluetooth module, which is attached to
this Controller. For each sample, the Real-Time
Clock module produces a real date and time log.
A memory card is used to store the data file. And,
thanks to Bluetooth, each customer can save these
log data to their mobile device. Table 1 shows a milk
analyzer observation table.
