RCWL-9610 Ultrasonic Sensor 2022 Version 3 to 5v Ultrasonic Distance Module replace for HC-SR04 with support for I2C, UART and 1-Wire

  HC-SR04 (2022 Version RCWL-9610 Chip)
  ==========================================   
  GPIO Control Demonstration
  ------------------------------------------
  This Arduino sketch demonstrates using the (default) GPIO 
  mode of the HC-SR04 2022 Version to read a distance in 
  centimeters.
  The default configuration of the board is to use GPIO
  but if you have previously used one of the other modes
  ensure that the M1 and M2 jumper are both open 
  (no solder blob).
  -VCC               = 3.3V/5.5V
  -Trig_RX_SCL_I/O   = A5
  -Echo_TX_SDA       = A4
  -GND               = GND

 //  (you can change A4 and A5 to any other unused pins for GPIO mode)

  const int SR04_Echo_TX_SDA = A4;
 // Ensure the pins are in the correct mode

  pinMode(SR04_Trig_RX_SCL,OUTPUT);
 // We need to delay by at least 30ms between readings
 //  so we don't get a false reading

 // Read the distance pulse, 
 // the number of microseconds for a return trip at the speed of sound
  unsigned long microseconds  = pulseIn(SR04_Echo_TX_SDA,HIGH);
 // Sound travels in air at about 343 m/s at 20degrees C
 //  that is 343 / 1000000 m per microsecond
 //  that is ( 343 / 1000000  * 100) cm per microsecond
 // Note thoat we need to "cast" to a float here to calculate correctly
