The MaxBotix MB1240 XL-MaxSonar-EZ4 is a high-performance ultrasonic distance sensor module offering a 20-765 cm range with 1 cm resolution. It provides three simultaneous output options (Analog Voltage, RS232 Serial, and Pulse Width) for seamless integration with microcontrollers like Arduino, Raspberry Pi, and industrial PLCs.

Features

  • High-performance ultrasonic ranging with a 20-765 cm (7.65 m) detection range and 1 cm resolution.
  • Triple-output interface: Analog Voltage, RS232 Serial (TTL), and Pulse Width (PWM) for maximum compatibility.
  • Advanced noise rejection with real-time automatic calibration for voltage, humidity, and ambient acoustic conditions.
  • Compact, lightweight PCB design (22.5 x 20 mm) with integrated mounting holes for easy installation.
  • Designed for indoor applications requiring reliable detection of larger objects with minimal dead zone.

Description

The MB1240 XL-MaxSonar-EZ4 utilizes a 42 kHz ultrasonic transducer to provide precise, non-contact distance measurements. Its advanced firmware incorporates real-time waveform signature analysis and continuously variable gain to deliver virtually noise-free readings, even in electrically or acoustically noisy environments. This makes it suitable for applications where consistent, reliable data is critical.

Engineered for indoor use, the sensor features a narrow detection beam pattern, the narrowest in the XL-MaxSonar-EZ series, which helps isolate targets and reduce clutter from surrounding objects. The module’s real-time background automatic calibration continuously adjusts for changes in supply voltage and environmental conditions, ensuring stable long-term operation without manual intervention.

Key Features

  • High-output acoustic power with a hardware gain of 250 for extended range and signal integrity.
  • Virtually no dead zone; objects closer than 20 cm are reported as 20 cm.
  • Advanced firmware filtering for superior noise tolerance and environmental clutter rejection.
  • Robust construction with a rated Mean Time Between Failure (MTBF) exceeding 200,000 hours.
  • Low power consumption, averaging 3.4 mA during operation, compatible with 3.3V and 5V systems.
  • Compact form factor (22.5 x 20 mm PCB) with a 16 mm sensor cover diameter.
  • Simultaneous Analog, Serial (RS232/TTL), and Pulse Width outputs provide flexible interfacing options.

Applications

  • Indoor robotics for obstacle avoidance and navigation in constrained spaces.
  • Industrial tank or bin level monitoring for non-contact measurement of bulk materials.
  • People detection and presence sensing for security or building automation systems.
  • Proximity sensing and object detection on conveyor belts or assembly lines.
  • Interactive installations and exhibits requiring reliable, medium-range distance input.

Frequently Asked Questions

What are the output options of the MB1240 sensor and how do I connect them?

The MB1240 provides three simultaneous outputs: a 0-Vcc analog voltage proportional to distance, a TTL-level RS232 serial data stream, and a pulse width (PWM) signal. You can use any one of these interfaces. For the analog output, connect to an ADC pin on your microcontroller. For serial, connect the RX/TX lines to a UART. For PWM, measure the pulse width on a digital input pin capable of pulseIn() functions.

Is the MB1240 suitable for outdoor use or detecting small objects?

No, the MB1240 is designed for indoor use only. Its performance can be adversely affected by environmental factors like wind, rain, and extreme temperatures outdoors. Furthermore, it is optimized for detecting larger objects due to its narrow beam pattern; for small target detection, other models in the MaxBotix lineup with wider beams may be more appropriate.

How does the automatic calibration work, and do I need to recalibrate it?

The sensor performs real-time background automatic calibration, continuously adjusting for changes in supply voltage, humidity, and ambient acoustic noise. This process runs transparently, meaning no user-initiated calibration is required under normal operating conditions. The firmware's noise rejection algorithms help maintain accuracy even in challenging environments.

What is the power requirement and current draw of the MB1240?

The module operates from a 3.3 to 5.5 V DC supply. Its average current consumption is approximately 3.4 mA during operation, making it suitable for battery-powered applications. Ensure your power source can provide clean, stable voltage within this range for optimal performance and sensor longevity.
