Description

The MB7569-100 utilizes a 42 kHz ultrasonic transducer combined with sophisticated firmware algorithms to deliver virtually noise-free distance readings. Its key innovation is the “largest target” detection mode, which prioritizes the strongest acoustic return while ignoring smaller clutter, making it exceptionally reliable for applications like tank level measurement where surface conditions or obstructions may vary.

Engineered for harsh environments, the sensor features internal temperature compensation and a self-cleaning transducer design. It operates across an industrial temperature range of -40°C to +70°C. The sensor’s long, narrow detection zone and 1 mm resolution provide precise ranging, with a virtually non-existent dead zone—objects closer than 30 cm are typically reported as 30 cm.

Key Features

  • Advanced Signal Processing: Real-time waveform signature analysis and noise rejection algorithms ensure stable readings amidst electrical or acoustic interference.
  • Robust Environmental Sealing: IP67-rated PVC housing protects against dust and temporary immersion, suitable for outdoor and industrial use.
  • Integrated Mounting Solution: Housing matches standard 3/4-inch electrical PVC pipe fittings (3/4-inch NPT) for straightforward installation.
  • Triple-Output Interface: Delivers distance data concurrently via analog voltage output, serial TTL interface, and a pulse width output for maximum system compatibility.
  • Continuous Self-Calibration: Automatically calibrates for changes in supply voltage, ambient humidity, and background noise in real-time.
  • Wide Operating Range: Functions from 2.7V to 5.5V, making it compatible with both 3.3V and 5V logic systems.
  • Extended Temperature Operation: Reliable performance from -40°C to +70°C for use in extreme climates.
  • High-Value Build: RoHS-compliant construction with a durable, optimized design for long-term reliability in demanding applications.

Applications

  • Outdoor Tank and Bin Level Monitoring: Ideal for measuring contents in water tanks, grain silos, or chemical storage bins, even with surface icing or condensation.
  • Industrial Process Control: Provides non-contact distance feedback for conveyor systems, robotic palletizing, and material handling equipment.
  • Marine and Harsh Environment Ranging: Used in boat docking systems, tide level monitoring, or flood warning systems due to its IP67 rating.
  • Agricultural Automation: Monitors liquid levels in irrigation reservoirs or feed levels in livestock troughs.
  • Parking Guidance and Vehicle Detection: Suitable for outdoor parking space occupancy systems or vehicle detection at gates.

Frequently Asked Questions

What are the three output types available on the MB7569-100 sensor?

The MB7569-100 provides three simultaneous, real-time outputs: an analog voltage pin where the voltage scales linearly with distance, a serial TTL interface (TX pin) that outputs ASCII characters representing the range in millimeters, and a pulse width (PW) pin where the pulse duration is proportional to distance. This allows you to choose the simplest interface for your specific microcontroller (Arduino, Raspberry Pi, PLC) or system design.

How does the 'largest target' detection feature work?

The sensor's advanced firmware analyzes the return echo waveform and selects the largest acoustic reflection within its field of view. It ignores smaller, closer clutter. If multiple targets have similar amplitude, the closest one is reported. This filtering provides exceptional stability in environments with raindrops, dust, insects, or structural obstructions, making it ideal for measuring liquid or bulk solid levels in tanks.

What is the power supply requirement and how do I wire it?

The module operates from a wide 2.7V to 5.5V DC supply, compatible with both 3.3V and 5V systems. Connect Vin (pin 1) to your positive supply and GND (pin 2) to ground. The three output pins (3, 4, 5) correspond to Analog Voltage, Serial TX, and Pulse Width. No external components are needed for basic operation, but a 100nF bypass capacitor near the sensor's power pins is recommended for noisy electrical environments.

Can this sensor be used for outdoor applications and how do I mount it?

Yes, its IP67-rated PVC housing is designed for outdoor use, protecting against dust and temporary water immersion. The housing has standard 3/4-inch National Pipe Thread (NPT) straight threads, allowing it to be screwed directly into a compatible threaded fitting or adapter. Ensure the sensing face is unobstructed and angled correctly towards the target for optimal performance.

What is the sensor's dead zone and how fast does it update?

The sensor has a virtually non-existent dead zone; objects closer than the minimum 30 cm range are typically reported as 30 cm. The read rate is approximately 0.58 Hz, meaning it takes about 1.72 seconds to complete one full measurement cycle, which includes the ping and processing time. This rate is optimized for stability and noise rejection in industrial level-sensing applications.
