The RCWL-1601 is a compact and reliable ultrasonic ranging module designed for precise non-contact distance measurement. It is widely used in robotics, automation, smart systems, and industrial applications where accurate distance sensing is required. The module features a very small blind spot of only 2-3 cm and supports long-range detection up to approximately 400-450 cm. Its low power consumption and small physical size make it ideal for embedded and portable projects.
This sensor operates using a 40 kHz ultrasonic signal and maintains stable readings even when detecting soft, irregular, or fabric-based objects, which can be difficult for traditional infrared sensors. The RCWL-1601 provides high accuracy with ;2% error, a resolution of 1 mm, and a fast measurement cycle of 50 ms, allowing it to be used in real-time systems. It communicates through a simple GPIO interface and works with standard microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi.
