Waterproof Ultrasonic Distance Sensor

SKU: SEN0301

This is a high-performance ultrasonic distance sensor (ULA) with an enclosed waterproof probe. Using ultrasonic echo ranging (non-contact, measuring time lapses between pulse send and echo receive), it detects various objects (transparent, non-ferrous, metal/non-metal, liquid, solid, powder). Its unique bell-mouth shell boosts ultrasound directivity and stability. It offers two output modes: RS232 (default, changeable via button) and voltage analog.
