DYP-A21AYYCAW-V1.0 CAN Ultrasonic Obstacle Avoidance Sensor (Object Range 3~500cm)

The DYP-A21AYYCAW-V1.0 sensor operates from a wide 3.3V to 24V DC power supply. This flexibility allows for direct integration with low-voltage microcontroller systems (3.3V/5V) as well as standard industrial 12V or 24V DC power rails without requiring an additional voltage regulator.

This sensor uses a CAN bus (Controller Area Network) interface for communication. You will need a CAN transceiver or a microcontroller with an integrated CAN controller (like many STM32 or Arduino boards with MCP2515 shields) to interface with it. Standard two-wire CAN_H and CAN_L connections are required, following typical 120-ohm termination practices for network stability.

Yes, the DYP-A21 module is fully configurable. Key parameters such as the CAN bus baud rate, the device's node address, the detection angle, and the power supply noise reduction level can all be modified via configuration commands sent over the CAN interface, allowing for customization and multi-sensor network setups.

The module incorporates intelligent acoustic processing technology that identifies and filters out same-frequency ultrasonic interference. This significantly reduces the probability of erroneous readings in environments with multiple ultrasonic sensors or other acoustic noise sources, ensuring more stable and reliable distance data.

Yes, the DYP-A21 sensor is built with a high IP-grade (Ingress Protection) enclosure that is both dustproof and waterproof. This robust construction makes it suitable for deployment in outdoor applications, robotic platforms operating in damp conditions, and industrial environments where exposure to dust or moisture is a concern.
