The RCWL-1605 Ultrasonic Ranging Module is a compact, low-power, and highly versatile distance-measuring sensor designed for Arduino and other microcontroller platforms. Featuring a transceiver-integrated open ultrasonic design, it offers full HC-SR04 compatibility by default, making it an easy drop-in replacement with enhanced performance.

Powered by the advanced RCWL-9625/9623 chipset, the module provides a wide 2.8–5.5V operating range, simplified peripheral circuitry, and multiple communication options, including GPIO, UART, I²C, and 1-Wire. With a 25cm ultra-small blind zone, 4.5m typical max detection range, and only 2mA working current, it is suitable for both battery-powered and embedded applications.

Key Features

  • 25cm ultra-short blind zone for close-range precision
  • Up to 4.5m typical maximum range
  • Ultra-low power consumption: only 2mA working current
  • Wide operating voltage: 2.8V–5.5V
  • Multiple communication modes:
    • GPIO (HC-SR04 compatible default mode)
    • UART
    • I²C
    • 1-Wire
  • Built-in RCWL-9625 / RCWL-9623 professional ultrasonic processing chip
  • 450ms measurement cycle
  • Compact, transceiver-integrated open ultrasonic structure
