DYP Sensor A08A /A08B IP67 Waterproof Ultrasonic Precision Rangefinder For 25cm – 800cm Distance Measurement

The DYP Sensor A08 is an IP67 waterproof ultrasonic precision rangefinder designed for reliable distance and level measurement in outdoor, industrial, and embedded applications. It uses a 40 kHz ultrasonic transducer with intelligent matching technology to maintain stable performance across changing environments.
This ultrasonic precision rangefinder is well-suited for sewer-level monitoring, river-level measurement, narrow-angle horizontal ranging, smart-waste-bin fill-level detection, and height-measurement systems. Its waterproof housing, low-power design, and multiple output options make it easy to integrate into IoT devices, automation systems, and battery-powered products.
The A08 series is available in application-focused variants. The A08A series is mainly used for plane-distance measurement with a stable range of 25 cm to 800 cm and a small beam-angle for long-distance ranging. The A08B series is designed for human-body distance measurement with high sensitivity and a wider detection angle. The A08C series is developed for smart-waste-bin level measurement and includes a built-in frame-filtering algorithm to reduce interference from bin walls and baffles.
Key Features

IP67 Waterproof Design: Suitable for outdoor, humid, and splash-prone environments.
Wide Detection Range: A08A supports stable plane-object measurement from 25 cm to 800 cm.
Centimetre Resolution: Provides easy-to-read distance values for precision-ranging applications.
Temperature Compensation: On-board temperature correction helps maintain stable readings from -15 deg C to +60 deg C.
40 kHz Ultrasonic Operation: Measures distance using ultrasonic reflection for non-contact sensing.
Low-Power Consumption: Static current is less than 5 uA and operating current is less than 15 mA.
Multiple Output Modes: Supports PWM processing-value output, UART automatic output, and UART controlled output for flexible integration.
Smart-Waste-Bin Support: A08C includes frame-filtering logic to filter interference between 30 cm and 80 cm.
High Measurement Accuracy: Plane-object accuracy is +/- 1 + S x 0.3% cm, where S is the measured distance.
Compact And Lightweight Module: Easy to fit into embedded projects, industrial devices, and product enclosures.
RoHS Compliant: Suitable for applications requiring restricted-substance compliance.
