The RCWL-1605 Ultrasonic Distance Sensor Module is a compact and energy-efficient ultrasonic ranging solution designed for robotics and automation systems. Powered by the RCWL-9623 chip, it delivers reliable distance measurements up to 4.5 meters while maintaining a very low operating current of only 2mA. Because it supports a wide voltage range from 2.8V to 5.5V, the module integrates seamlessly with 3.3V and 5V microcontrollers such as Arduino, ESP32, and STM32. By default, it is fully compatible with the popular HC-SR04 timing interface, which makes upgrading or replacing existing modules simple and cost-effective. Moreover, developers can configure UART, I2C, or 1-WIRE communication modes by adjusting onboard resistors, offering greater design flexibility. With a 50ms measurement period and compact design, this module suits both indoor and outdoor sensing applications. Featured By RoboticsBD.
