DYP Sensor A01A IP67 Waterproof Ultrasonic Precision Rangefinder For 28cm ~ 750cm Long-Distance Flat-Object Measurement

The DYP Sensor A01A IP67 Waterproof Ultrasonic Precision Rangefinder is designed for accurate long-distance non-contact measurement of flat objects. With a 28 cm to 750 cm measuring range, mm-level resolution, internal temperature compensation, and IP67 enclosure protection, it is well-suited for outdoor sensing, smart-parking systems, waste-bin fill-level detection, and slow-moving target detection.

This waterproof ultrasonic rangefinder uses a 40 kHz ultrasonic transducer and firmware-filtering technology to improve noise tolerance and clutter rejection. Its long, narrow detection zone helps focus measurement on the intended target, making it useful where stable distance feedback is required in compact embedded-control and automation designs.

The A01 series supports multiple application variants. The A01A series is designed for high-accuracy flat-object distance measurement. The A01B series is designed for stable human-body detection. The A01C series is designed for waste-bin level sensing with a dedicated algorithm to filter bin borders and interfering objects. The A01A model supports flexible interface options including UART auto, UART controlled, PWM auto, PWM controlled, switch, and RS485 output.

Key Features

• Long Measuring Range: Detects flat objects from 28 cm to 750 cm for short-to-long distance sensing.
• 28 cm Dead Zone: Objects closer than 28 cm are treated as 28 cm, supporting stable near-range handling.
• MM-Level Resolution: Provides fine distance feedback for precision ultrasonic ranging applications.
• High Measurement Accuracy: Flat-object measuring accuracy is 1 plus S x 0.3%, where S is the measuring distance.
• IP67 Waterproof Enclosure: Dustproof and waterproof enclosure supports outdoor, wet, and harsh-use environments.
• 40 kHz Ultrasonic Sensing: Uses 40 kHz ultrasonic measurement for reliable distance detection.
• Internal Temperature Compensation: Helps maintain stable measurement performance under changing ambient conditions.
• Multiple Output Interfaces: Supports UART auto, UART controlled, PWM auto, PWM controlled, switch, and RS485 output.
• Wide Input Voltage Options: Supports 3.3 V to 5.0 V and 5.0 V to 12.0 V input-voltage options.
• Low-Power Operation: Average current requirement is 10.0 mA, with standby current lower than 10 uA.
• Firmware Noise Filtering: Improves noise tolerance and clutter rejection in demanding measurement environments.
• Long Narrow Detection Zone: Helps focus sensing on the intended object for smart-parking and level-detection use.
• Compact Lightweight Module: Small and light-weight design supports easy integration into products and projects.
• CE And RoHS Compliant: Suitable for compliant electronic product designs and industrial-use applications.
