The MB7574 SCXL-MaxSonar-WRST7 is a weather-resistant ultrasonic distance sensor designed for outdoor use. It provides millimetre-resolution measurements from 500mm to 5000mm with a 0.58Hz read rate, and includes three output options: analog voltage, TTL serial, and pulse-width.
Housed in a compact IP67-rated PVC enclosure compatible with standard 3/4-inch PVC pipe fittings, the sensor features a self-cleaning transducer to reduce the impact of condensation and frost. Internal temperature compensation and real-time automatic calibration ensure accurate readings across varying environmental conditions.
Key Features
- Weather Resistant (IP67) – Rugged PVC housing suitable for outdoor and high-moisture environments
- Self-Cleaning Transducer – Reduces impact of condensation, frost, and debris
- 1mm Resolution – High-precision distance measurements with rate-limiting filter
- Three Output Modes – Analog voltage, TTL serial, and pulse-width
- Internal Temperature Compensation – Accurate readings without external calibration
- Real-Time Automatic Calibration – Compensates for voltage, humidity, and ambient noise
- Advanced Noise Rejection – Waveform signature analysis and continuously variable gain for clean readings
- Narrow Beam Pattern – Factory calibrated for long-range, focused detection

Jargon buster
Plain-language definitions for the technical terms used above.
- IP67
- An ingress protection rating meaning the enclosure is dust-tight and can survive temporary immersion in water under specified test conditions. This matters when choosing a sensor for outdoor, wet, or wash-down environments.
- Temperature compensation
- Temperature compensation is when a sensor or instrument adjusts its readings to reduce errors caused by changes in temperature. This matters because a sensor's raw output often drifts as conditions warm or cool, so compensation keeps readings more consistent and accurate over time.
- TTL serial
- A simple serial data connection that uses microcontroller logic-level voltages (typically 3.3 V or 5 V) rather than the higher, inverted voltages of computer RS-232. When a device lists TTL serial, it can usually wire straight to a microcontroller's UART pins or to a USB-to-TTL serial adapter, but it needs a level converter before connecting to a true RS-232 port.
