MaxBotix MB7092 XL-MaxSonar WRMA1 Ultrasonic Precision Rangefinder Sonar

The MB7092 provides three simultaneous outputs: RS232 serial (9600 baud, 8-N-1 format), analog voltage (scaling is Vcc/1024 per centimeter), and an analog envelope signal for advanced signal processing. The serial output provides direct digital readings, while the analog voltage pin outputs a variable voltage proportional to distance, easily read by an ADC. All outputs are active concurrently, allowing you to choose the most convenient interface for your microcontroller, PLC, or DAQ system.

Yes, the MB7092 is designed for outdoor use with an IP67-rated PVC housing, making it resistant to dust and temporary water immersion. It features standard 3/4-inch electrical PVC pipe threads on its housing, allowing for direct screw-in mounting to conduit or custom brackets. This rugged design and mounting option make it ideal for permanent installation in weather-exposed applications like tank level monitoring or agricultural robotics.

The XL-MaxSonar algorithm is configured to report the distance to the target with the largest acoustic return within its beam pattern. If a large object is behind a smaller obstruction (like a fence), the sensor will typically range the larger object. This feature, combined with small target rejection, helps ignore clutter like grass or raindrops, providing more stable readings for the primary object of interest in complex environments.

The sensor operates from a 3.0V to 5.5V DC supply. Its average current consumption is very low at 3.4 mA, with peak currents during acoustic pulse transmission being higher but brief. This low average draw makes it highly suitable for battery-powered and solar-powered applications where energy efficiency is critical. Ensure your power supply can deliver clean, stable voltage within the specified range.

Yes, the MB7092 supports both free-run and triggered modes of operation. In free-run mode, it continuously measures and outputs data at its 10 Hz rate. By using the dedicated trigger pin, you can command the sensor to take a single, on-demand reading. This is useful for synchronizing measurements with other system events or for further reducing power consumption by keeping the sensor in a low-power idle state between triggered readings.
