DYP Sensor A22 IP67 Waterproof Ultrasonic Sensor For 2cm~300cm Robot Obstacle Avoidance And Reliable Distance Detection
The DYP Sensor A22 IP67 Waterproof Ultrasonic Sensor is designed for accurate non-contact distance detection in robot-control, obstacle-avoidance, automation, water-surface-cleaning, lawn-mowing, and solar-panel-cleaning applications. With a 2 cm to 300 cm detection range, millimetre-level resolution, and a compact waterproof body, it is well-suited for embedded systems that need stable sensing in compact spaces.
This ultrasonic obstacle-avoidance sensor uses intelligent acoustic-wave processing to identify and filter co-frequency interference. When interference is detected, the module can output FFFE data as a prompt, helping the system improve reliability in complex robot-automation environments. The correct rate can be increased by 80% in co-frequency interference conditions.
The A22 module supports multiple output options, including UART automatic output, UART controlled output, RS485, and IIC. It also supports adjustable baud-rate settings, 5-grade noise-reduction settings, configurable measuring angles, and selectable range levels. Its IP67 waterproof structure and -25 deg C to +65 deg C operating-temperature design make it suitable for indoor, outdoor, wet, dusty, and harsh-use conditions.
Key Features
2 cm Blind Zone: Standard blind area is 2 cm, and the product blind area can reach 1.5 cm minimum depending on configuration and test conditions.
2 cm To 300 cm Detection Range: Supports short-range and medium-range obstacle detection for robotic and automation systems.
Millimetre-Level Resolution: Provides fine distance-detection feedback for stable robot navigation and object sensing.
IP67 Waterproof Protection: Dustproof and waterproof structure supports use in wet, outdoor, and harsh measurement environments.
Wide Voltage Input: Operates from 3.3 V to 12 V, with maximum support up to 24 V as specified.
Adjustable Baud Rate: Default baud rate is 115200 bps, with support for 4800, 9600, 14400, 19200, 38400, 57600, and 76800 bps.
Fast Response Time: Ms-level response supports data output as fast as 13 ms for responsive obstacle detection.
Configurable Range Levels: Supports 4-level farthest-range settings of 50 cm, 150 cm, 250 cm, and 350 cm through instructions.
Selectable Detection Angle: Single-angle detection supports 4-level settings of 30 deg, 40 deg, 50 deg, and 60 deg for different installation needs.
5-Grade Noise Reduction: Built-in noise-reduction settings support battery power, USB power, switching power supply, and large-noise power-supply environments.
Co-Frequency Interference Filtering: Built-in algorithm identifies interference sound waves and automatically performs filtering for more reliable output.
Wide Operating Temperature: Works from -25 deg C to +65 deg C for demanding industrial and outdoor applications.
High Installation Adaptability: Compact reflective construction supports flexible installation in robot-control and embedded-sensing projects.
