Output format: Output of one module each, with four 8-bit data frame format is: 0XFF + H_DATA + L_DATA + SUM1.0XFF: As a starting data for judgments. 2. H_DATA: From the high 8-bit data. 3. L_DATA: From the lower 8 bits of data. 4. SUM: Data and, for efficacy. The 0XFF + H_DATA + L_DATA = SUM (lower 8-bit only)5. H_DATA and L_DATA synthetic 16-bit data, ie the distance in millimeters values. Note: The module detects minimum distance of 14cm, 14cm inside the object, will receive inaccurate signals.
