Instructions for Use

1. Power Supply: Connect the VCC pin to a 5V DC power supply and the GND pin to ground.
2. Trigger Pulse: Send a 10渭s high-level pulse to the TRIG pin to start the ranging.
3. Echo Signal: The module will automatically send out an ultrasonic signal and return a high-level pulse on the ECHO pin. The duration of this high-level pulse is proportional to the distance to the object.
4. Distance Calculation: The distance can be calculated using the formula: [ text{Distance (cm)} = frac{text{Pulse Width (渭s)}}{58} ] Alternatively, you can use: [ text{Distance (inches)} = frac{text{Pulse Width (渭s)}}{148} ]
5. Non-Blocking Operation: Ensure that the sensor is not blocked by any objects directly in front of it during operation.
6. Mounting: Mount the sensor in a stable position with the ultrasonic transducer facing the direction of measurement.
7. Multiple Sensors: If using multiple sensors, ensure they are at least 30cm apart to avoid interference.
8. Software Debouncing: Implement software debouncing to filter out any noise or false triggers.
