Ultrasonic sensor module

YTK-A6 serial ultrasonic ranging module is a high performance, cost-effective non-contact distance sensor module, measuring range of 0.02 ~ 4.00m, accuracy 1cm, measurement without direct contact with the measured object, can clearly show a steady measurement results

• Small, easy to use
  
• low voltage, low power consumption
  
• Wide measurement range
  
• high accuracy
  
• with temperature compensationApplication

Application:

• Applications ranging occasions;
  
• measuring the distance between objects:
  
• Programmable car obstacle avoidance:
  
• robot obstacle avoidance:
  
• teaching apparatus;
  
• security, industrial control

Instructions for use:

• This module will occupy in the use of a microcontroller IO port, connect the power, the modules within the distance once every 50ms, and from the pin OUT one, with four 8-bit data frame format is: 0XFF + H_DATA + L_DATA + SUM
  1. 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)
  Note: H_DATA and L_DATA synthetic 16-bit data, ie the distance in millimeters values.
