MB7389 HRXL-MaxSonar-WRMT Outdoor Ultrasonic Sensors from MaxBotix

The MB7389 from the HRXL-MaxSonar-WR line of outdoor sensors is a rugged ultrasonic sensor component module. This sensor comes in a compact and robust PVC housing that meets the IP67 water intrusion standard and matches standard electrical 3/4‑inch PVC pipe fittings (this product has multiple housing options available).

The HRXL-MaxSonar-WR sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones.

The MB7389 is reports the distance to the largest acoustic return while ignoring smaller targets. When targets are of similar amplitude reflections, it gives preference to close targets. This gives users the flexibility to consistently detect larger targets in the presence of clutter and noise.
Features
Internal temperature compensation
Read from all 3 sensor outputs: Analog Voltage, Serial, Pulse Width
Virtually no sensor dead zone, objects closer than 30cm typically range as 30cm
Small, lightweight module
Designed for easy integration into your project or product
Real-time automatic calibration (voltage, humidity, and ambient noise)
Firmware filtering for excellent noise tolerance and clutter rejection
Weather-resistant (IP67)
Matches standard electrical 3/4-inch PVC pipe fittings for easy mounting (3/4-inch National Pipe Thread Straight)
The long, narrow detection zone
Our most advanced weather-resistant, ultrasonic sensor
Additional stability filter rejects anomalous readings
Detects the largest signal return in the field of view
Uses the complete dynamic range of the sensor, if no large targets are present the sensor will select the next smallest target in view
Can be used to range large objects behind small obstructions
The best sensor for bin and tank level measurements
The maximum range of 500 cm (196 inches)
