Tell me the meaning of the code

const int a = sensor1;
const int b = sensor2;
const int c = sensor3;
const int d = sensor4;

if (a == LOW || b == LOW || c == LOW || d == LOW )

What does this code mean?

Int is said to be a read/write data type and constant is a read-only data type.

Sensors 1, 2, 3, and 4 are connected to a, b, c, and d, respectively It seems to mean "when the value of a or b or c or d is outputting the LOW signal (0V).

Actually, I don't know what Arduino is, but I googled it and answered it.
