Description

This ultrasonic distance sensor module utilizes a time-of-flight (ToF) measurement principle. A control signal triggers a transmitted ultrasonic pulse, and the time delay until the echo is received is measured to calculate distance. The integrated waterproof transducer ensures stable performance in environments with moisture, dust, or light splashing.

The module is designed for straightforward integration into control systems. It requires a simple digital trigger pulse and provides a digital echo output, making it compatible with most microcontrollers’ input capture or timing functions. Its operating temperature range of -20°C to 70°C supports use in varied climatic conditions.

Key Features

  • Waterproof transducer housing for durable performance in damp or outdoor applications.
  • High-precision time-of-flight measurement with 1mm resolution.
  • Wide 3V to 5.5V operating voltage range supports 3.3V and 5V logic systems.
  • Optimized for low power consumption with a 30mA operating current.
  • Strong anti-interference design for reliable operation in electrically noisy environments.
  • Compact form factor (41.3mm x 29mm) for space-constrained installations.
  • Standard 2.54mm pitch pin header for easy connection to breadboards or PCBs.

Applications

  • Outdoor robotics for obstacle detection and avoidance in wet conditions.
  • Industrial level sensing and inspection in non-contact, harsh environments.
  • Security system perimeter monitoring and intrusion detection.
  • Vehicle reversing aid and parking sensor systems.
  • Automated control and object proximity sensing for smart agriculture.

Frequently Asked Questions

What is the operating voltage range for this ultrasonic sensor module?

The module operates from 3.0 to 5.5 volts DC. This range makes it directly compatible with both 3.3V logic systems (like ESP32 or Raspberry Pi) and standard 5V Arduino boards without requiring a logic level shifter.

How do I interface this module with an Arduino or other microcontroller?

Interface requires two digital I/O pins: one for the Trigger (input) and one for the Echo (output). Send a 10µs high pulse to the Trigger pin to initiate a measurement, then monitor the Echo pin for a high pulse. The duration of the high Echo pulse corresponds to the distance to the target.

Is the sensor itself waterproof, or just the module?

The ultrasonic transducer (emitter/receiver) is sealed within a waterproof housing, making the sensing element protected against water and dust. The PCB module should be mounted in a protected enclosure or conformally coated for full outdoor weatherproofing.

What is the minimum and maximum measurable distance?

While exact min/max range is not specified in the provided data, typical modules of this type have a minimum range of 2-3cm and a maximum range of 4-5 meters. Performance can be affected by target material, angle, and environmental conditions.

Can this sensor be used for continuous monitoring?

Yes, the module supports continuous cycle measurement. You must ensure adequate timing between measurement pulses (a recommended cycle period of >60ms) to allow echoes to settle and prevent interference from previous pulses.
