MaxBotix MB7052 XL-MaxSonar-WRM1 Outdoor Ultrasonic Sensor - PVC Housing, IP67, 3-5.5V

The MB7052 provides Analog Voltage, Serial TTL, and Pulse Width outputs simultaneously. The analog pin outputs a scaled voltage relative to distance (Vcc/512 per cm). The serial pin outputs an ASCII 'R' followed by the range in cm. The pulse width pin outputs a signal whose duration corresponds to the measured distance. You can use any one or monitor all three with your microcontroller.

Yes, the sensor is specifically designed for harsh outdoor environments. Its PVC housing is rated IP67, meaning it is dust-tight and can withstand temporary immersion in water up to 1 meter for 30 minutes. Combined with an operating temperature range of -40°C to +70°C, it is built for reliable year-round operation in rain, snow, and extreme temperatures.

The sensor features standard 3/4-inch National Pipe Thread (NPT) fittings on its housing, allowing direct screw-in mounting to compatible conduit or custom brackets. Power is supplied via the V+ and GND pins within the 3.0V to 5.5V DC range. Ensure wiring is secure and consider using the included thread seal tape for a watertight seal if mounting directly into a pipe fitting.

The sensor's firmware performs real-time automatic calibration, continuously adjusting for changes in supply voltage, humidity, and ambient acoustic noise. Advanced algorithms perform waveform signature analysis to distinguish true target echoes from background electrical or acoustic interference, providing stable readings even in noisy industrial or outdoor settings.
