Description

The LDRobot STU-22L Ultrasonic Material Detection Sensor operates on the pulse-echo principle, emitting ultrasonic waves and analyzing the reflected signal to determine both distance and material properties. This allows it to differentiate between material types within its 2-6 cm range, a critical function for sorting and quality control.

Engineered for industrial environments, the sensor provides a stable 100Hz update rate via its UART or configurable digital I/O interface, ensuring real-time feedback for automation processes. Its robust design supports reliable operation in varied conditions, making it a core component for precise material handling systems.

Key Features

  • High-Speed Ultrasonic Sensing: 100Hz sampling frequency enables real-time material detection and distance tracking.
  • Material Differentiation Capability: Advanced signal processing distinguishes between different material types based on acoustic reflectance.
  • Dual Communication Interface: Offers both UART (serial) and configurable digital I/O for compatibility with a wide range of controllers and PLCs.
  • Compact & Lightweight Design: Ultra-small 14mm x 11mm footprint and 1g weight allow for integration into compact robotic grippers and machinery.
  • Focused Detection Field: 45° field of view provides precise, localized sensing to minimize false triggers from peripheral objects.
  • Wide Storage Temperature Range: Rated for -30°C to 70°C, ensuring reliability during shipping, storage, and non-operational periods.

Applications

  • Robotic gripper material identification and proximity sensing in pick-and-place systems.
  • Precise level monitoring and material presence detection in compact dispensing machines.
  • Object recognition and sorting based on material type in automated assembly lines.
  • Short-range obstacle detection for small AGVs (Automated Guided Vehicles) and drones.
  • Quality control checks for material presence and correct positioning in micro-assembly.

Frequently Asked Questions

What is the operating voltage for the STU-22L sensor?

The provided specifications do not list an operating voltage. Typically, similar LDRobot ultrasonic modules operate at 3.3V or 5V DC. You must consult the official product datasheet or wiring diagram for the exact voltage requirements and pinout before connecting to your power supply to prevent damage.

How do I communicate with the sensor using UART?

The STU-22L provides a UART (Serial) interface. You will need to connect the sensor's TX and RX pins to your microcontroller's corresponding RX and TX pins. Communication parameters (baud rate, data bits, parity) are typically defined in the product's protocol documentation, which must be referenced for proper command structure and data parsing.

Can this sensor differentiate between metal and plastic?

Yes, the STU-22L is designed for material differentiation. It uses ultrasonic reflectance characteristics to distinguish between materials like metal, plastic, and wood within its 2-6 cm range. The specific output for material type (e.g., a digital code or serial string) will be detailed in the sensor's communication protocol.

What is the meaning of the 'IO' interface option?

The 'IO' interface refers to a configurable digital Input/Output mode. In this mode, the sensor can output a simple digital signal (e.g., a high/low logic level) to indicate a condition like material detection or a threshold distance breach, simplifying integration with basic digital logic or PLCs without requiring serial communication.
