kkk = Device’s Serial ID. If the DA command is issued without an ID, the response omits this field.
Exception: the S40 family always includes both ID fields, even when a DA command without an ID is
issued.
+nnnn+ee = Main instantaneous gas concentration (for S40 family, this is NO)
ss = Status byte with the following bit map:
