Instructions for Use:

1. Connection Setup:

   • Connect the VCC pin to a 5V power supply.
   • Connect the GND pin to the ground.
   • Connect the TRIG pin to the trigger signal input from your microcontroller.
   • Connect the ECHO pin to read the echo signal back into your microcontroller.

2. Operation:

   • To start ranging, send a 10us high-level pulse to the TRIG pin.
   • The module will automatically send out an ultrasonic burst and wait for the echo.
   • The ECHO pin will output a high-level pulse whose duration corresponds to the time taken for the sound to travel to and from the object.

3. Calculation:

   • Distance can be calculated using the formula: Distance (cm) = Time (μs) / 58 or Distance (inches) = Time (μs) / 148.
   • Ensure that the measurement area is free of obstructions to ensure accurate readings.

4. Precautions:

   • Avoid placing the sensor too close to large reflective surfaces other than the target to prevent erroneous readings.
   • Do not expose the sensor to water or moisture as it may damage the internal components.
