Description

The MB7388 utilizes a 42kHz ultrasonic transducer paired with sophisticated firmware to deliver precise, noise-immune distance readings. Its real-time automatic calibration accounts for voltage fluctuations, humidity, and ambient acoustic noise, ensuring stable performance in dynamic environments. The sensor’s continuously variable gain and waveform signature analysis provide excellent clutter rejection, making it ideal for applications with multiple or irregular targets.

Engineered for harsh conditions, the sensor operates across an industrial temperature range of -40°C to +65°C. The compact PVC housing is sealed to IP67 standards, protecting against dust and temporary water immersion. This combination of precision, durability, and flexible electrical interfacing makes the MB7388 a premier choice for tank level monitoring, bin filling, robotics, and outdoor ranging systems.

Key Features

  • Millimeter resolution (1mm) for precise distance measurement.
  • Multi-layer target discrimination filters out clutter and noise.
  • IP67 weather-resistant PVC housing with standard pipe fittings.
  • Triple-output interface: Pulse-width, Analog Voltage (Vcc/512 per inch), and TTL Serial (9600 baud).
  • Real-time automatic calibration for voltage, humidity, and ambient noise.
  • Low average current draw of 2.9mA for energy-efficient operation.
  • Wide operating voltage range from 2.7V to 5.5V DC.
  • Robust performance from -40°C to +65°C operating temperature.

Applications

  • Outdoor tank and bin level monitoring in agriculture and industry.
  • Robotic obstacle detection and navigation in unstructured environments.
  • Process control and fill-level sensing in manufacturing and packaging.
  • Vehicle detection and parking assistance systems.
  • Weatherproof distance measurement for marine and outdoor equipment.

Frequently Asked Questions

What are the three output types from the MB7388 sensor?

The MB7388 provides three simultaneous output formats: a pulse-width pin where the pulse length scales with distance, an analog voltage pin that outputs Vcc/512 per inch, and a TTL serial (UART) interface operating at 9600 baud, transmitting 'R' + ASCII range data. This allows direct interfacing with microcontrollers (like Arduino), ADCs, or industrial PLCs without additional signal conditioning.

How does the multi-layer target filtering work?

The sensor's firmware analyzes the amplitude of all acoustic returns. It is designed to report the distance to the target with the largest acoustic reflection, effectively ignoring smaller clutter. If multiple targets have similar amplitudes, it defaults to the closest one. This intelligent filtering provides stable readings of the primary object in environments with rain, dust, or structural obstructions.

Can this sensor be used outdoors in all weather conditions?

Yes, the MB7388 is built for outdoor use. Its PVC housing is rated IP67, making it dust-tight and capable of withstanding temporary immersion in water up to 1 meter for 30 minutes. Combined with an operating temperature range of -40°C to +65°C and internal temperature compensation, it is suitable for year-round installation in tank farms, agricultural bins, and other harsh environments.

What is the power requirement and how do I connect it?

The sensor operates from a 2.7V to 5.5V DC supply, with an average current draw of only 2.9mA, making it suitable for battery-powered systems. Connection is straightforward via the 5-pin header: Pin 1 (PW), Pin 2 (AN), Pin 3 (TX), Pin 4 (+5V), and Pin 5 (GND). Ensure clean, stable power and use the TTL serial output for noise-immune digital communication over longer cable runs.
