Waterproof Ultrasonic Distance Sensor (27~800cm, ULS) Shipping:4-6 Days It adopts IPS hard screenThis is an ultrasonic distance sensor(ULS) of high performance with an enclosed waterproof probe. The sensor, like many other ultrasonic sensors, based on the principle of ultrasonic echo ranging, determines the distance to a target by measuring time lapses between the sending of a pulse and receiving of the echo without contacting. It can be used to detect transparent or non ferrous objects, metal or non metallic objects, liquid, solid, powder
