Frequently Asked Questions

What is the operating voltage range for the HS-SR04-L module?

The HS-SR04-L module is designed for dual-voltage operation, accepting a supply of either 3.3V or 5V DC. Ensure your power source matches one of these voltages and can provide sufficient current for stable transducer operation.

How do I interface the HS-SR04-L with an Arduino or Raspberry Pi?

Connect the module's PH2.0 connector to your controller's GPIO pins. Typically, you will need to connect the Trigger (input) and Echo (output) pins. The module uses a simple pulse-width timing protocol, with libraries widely available for platforms like Arduino IDE and Python (for Raspberry Pi).

What is the typical measurement range and blind zone of this ultrasonic sensor?

While exact specifications can vary, modules based on the HC-SR04 design typically have a range of 2cm to 400cm. The HS-SR04-L features an optimized design that reduces the blind zone, allowing for more reliable detection of objects very close to the sensor face, often as near as 2cm.
