Product Specification

HG-C40U Ultrasonic Range Finder Sensor & Module Description
? ATmega 8 MCU
? Measures distance from the obstacle and sends the data using UART communication.
? Within 5mm Resolution
? Optional two transmitting mode for various use.
  - Free Run : With a power supply, sensor transmits trigger and burst signal by itself (for basic application)
  - External Trigger : External system(controller or processor circuit) controls the trigger signals – for advance application
? Two types of input power – Low(5V) for processor circuit usage and High(12V) for controllers. ※ Factory Default : 12V
? Various Setting Option
  - Free Run / UART Trigger / External Trigger setting
  - Ring buffer use or not use setting
  - UART communication baudrate setting
  - Free Run Trigger interval
? Output Signal
  - Distance Data using UART(ASCII, mm)
  - Real time ultrasonic wave amplified from actually received ultrasonic.
  - Real time TTL level square signal(Square Wave) of detection signal.
? High performance ASIC Chip for stable transmission and sensitive reception.
? Sensor to PC communication using ‘Interface Board’(RS232, Power regulator)
? Data display using monitor program from PC(Hyperterminal available)
