DYP-A05LY4-V1.1 RS485 Ultrasonic Sensor Module - 25-45cm Range, 9-36V DC

The DYP-A05LY4-V1.1 sensor outputs distance data via an RS485 serial interface. It typically uses a Modbus RTU communication protocol, allowing for easy integration with PLCs, industrial HMIs, and data acquisition systems that support RS485. This provides noise immunity and enables reliable data transmission over distances up to 1200 meters.

This module requires a DC power supply between 9 and 36 volts. This wide range makes it directly compatible with common industrial voltage standards like 12V DC and 24V DC systems. The average operating current is less than 35mA, ensuring low power consumption for continuous operation in embedded control panels.

The module integrates four sealed ultrasonic transducers (probes) within its housing, enabling it to measure distances to objects in four distinct directions simultaneously. The sensing dead zone, or blind spot, is less than 25 cm from the sensor face. Objects must be beyond this minimum distance, up to the maximum of 45 cm, to be accurately detected.

Yes, the DYP-A05LY4-V1.1 is designed with integrated waterproof probes, making it resistant to dust and water ingress. This construction allows it to perform reliably in damp, wet, or harsh industrial conditions. However, for full submersion or high-pressure washdown, verify the specific IP rating is suitable for your application.

Direct connection to 5V microcontrollers like Arduino requires an RS485 to TTL converter module (e.g., MAX485). Connect the sensor's RS485 lines (A/B) to the converter, which then interfaces with the microcontroller's UART pins (RX/TX). For Raspberry Pi, a similar RS485 to USB or RS485 to GPIO UART adapter is needed, as the Pi's serial port operates at 3.3V TTL levels.
