DYP Sensor A02 IP67 Waterproof Ultrasonic Distance Sensor With 3 cm Blind Zone For Robot Obstacle-Avoidance, Liquid Level And Parking Applications

The DYP Sensor A02 IP67 waterproof ultrasonic distance sensor is designed for stable non-contact distance measurement in wet, dusty, and harsh environments. It uses a closed waterproof bistatic probe and compact PVC housing, making it well-suited for outdoor sensing, robot obstacle-avoidance, parking-management, object-proximity, and automatic-control applications.

With a 3 cm small blind zone and 3 cm – 450 cm measuring range, this ultrasonic sensor supports reliable short-range and mid-range detection. The 40 kHz ultrasonic sensing element, internal temperature-compensation function, real-time background calibration, and noise-suppression algorithms help deliver stable distance-value output with millimetre-level resolution.

The A02 series supports multiple output-interface options, including UART automatic output, UART controlled output, PWM pulse-width output, switch output, and RS485 output. Its low-power design, anti-static protection, and wide operating-temperature range make it suitable for commercial-grade embedded sensing and automation projects.
