Description: Ultrasonic distance sensor A02YYUW 3-450cm - waterproof - DFRobot SEN0311.
Ultrasonic distance sensor measuring the distance by measuring the time between sending and receiving a pulse. The A02YYUW is an easy to use, high quality distance sensor that features a much smaller dead zone, a wider measuring angle and resistance to water and dust, compared to other similar sensors. It allows to measure distances from 3 cm to 450 cm. It communicates through a UART serial interface. The module is powered from 3.3 V to 5 V. The sensor is enclosed in a waterproof housing with IP67 protection class.
Ultrasonic distance sensor A02YYUW - cable adapter for BLC female connectors included.
The sensor has been enclosed in a waterproof IP67 casing, which effectively protects it against water and dust, so it can be used in difficult conditions.
