Description

The MB1340 XL-MaxSonar-AE4 utilizes advanced ultrasonic time-of-flight (ToF) measurement with a 42 kHz operating frequency to deliver precise, noise-resistant distance data. Its integrated signal processing includes continuously variable gain, real-time waveform signature analysis, and clutter rejection algorithms, ensuring stable performance even in acoustically challenging environments.

Engineered for reliability, the sensor features a compact PCB design with mounting holes for easy integration into robotics, automation, and material handling systems. Its robust firmware provides a virtually non-existent dead zone, reporting objects closer than 20 cm as 20 cm, and offers a high mean time between failure (MTBF) exceeding 200,000 hours.

Key Features

  • High-output acoustic power with a hardware gain of 250 for superior signal integrity
  • Real-time background automatic calibration adapts to changing environmental conditions
  • Advanced noise rejection algorithms for operation near electrical or acoustic interference
  • Narrow beam pattern provides precise targeting and reduces false echoes from surroundings
  • Compact and lightweight module (22.5 x 20 mm PCB) with a 16 mm transducer diameter
  • Designed for indoor use, optimized for detecting larger target objects
  • Low average current consumption (3.4 mA) enables battery-powered applications
  • High-resolution output with 1 cm resolution for detailed distance mapping

Applications

  • Indoor robotics navigation and obstacle avoidance for larger objects
  • Material handling and warehouse inventory level monitoring
  • Proximity sensing and presence detection in automated guided vehicles (AGVs)
  • Liquid level monitoring in indoor tanks and containers
  • Interactive exhibits and security systems requiring reliable, noise-immune detection

Frequently Asked Questions

What is the operating voltage range for the MB1340 sensor?

The MB1340 operates from 3.3 to 5.5 volts DC. This wide range makes it directly compatible with common 3.3V and 5V microcontroller logic levels, such as those found on Arduino, Raspberry Pi, and ESP32 boards, without requiring a level shifter.

What output interfaces does this ultrasonic module provide?

It provides three simultaneous output interfaces: an analog voltage proportional to distance, an RS232 serial (TTL) data stream, and an analog envelope pin for advanced signal analysis. This flexibility allows integration with analog ADCs, direct serial communication, or oscilloscope-based debugging.

Is the MB1340 suitable for outdoor use?

No, the MB1340 is designed specifically for indoor applications. Its performance is optimized for stable indoor environments, and it may be affected by factors like wind, rain, and extreme temperature fluctuations if used outdoors. For outdoor ranging, consider a weather-resistant model from MaxBotix's outdoor product line.

How do I interpret the analog voltage output?

The analog voltage output scales linearly with distance. The exact scaling factor (V/cm or V/inch) is detailed in the product datasheet. You can connect this output directly to a microcontroller's ADC pin and use the provided scaling formula in your code to convert the voltage reading into a distance measurement.

What is the sensor's beam width and detection pattern?

The MB1340 features the narrowest beam pattern in the XL-MaxSonar-AE series, which helps in precisely targeting objects and reducing interference from off-axis clutter. The specific beam angle details are available in the official MaxBotix datasheet, but it is designed for detecting larger targets within its forward-facing cone.
