This ultrasonic time-of-flight (ToF) sensor utilizes the difference in energy of the ultrasonic echo signal on various surfaces to identify materials. Featuring ultra-low power, small size, and light weight, the ultrasonic material detection sensor is specially designed for material identification within a short range of 2-10cm.

The ultrasonic sensor can distinguish hard and soft materials and output information by IO (high/low) or UART. Compact and easy to install, it is mainly suitable for robotic cleaners to identify the floor material and automatically adjust the cleaning strategy according to the recognized ground information, thus achieving intelligent cleaning.
