Up to 400kHz I2C communication

that you can use if you want to make a basic user interface

They tend to draw ~30mA or so in practice but for precise numbers you must measure the current in your usage circuit

Output current up to 5A

Water-proof Ultrasonic Sensor (ULS) Brand_CodeBug Up to 400kHz I2C communicationThis 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
