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
