DFRobot URM13 Ultrasonic Sensor

DFRobot URM13 Ultrasonic Sensor is an ultrasonic ranging sensor with an open single-probe. The URM13 supports TRIG Pulse-triggered ranging (SR04 compatible), UART, and I²C communication protocols. This allows for more possibilities for actual using scenarios. The sensor works well with 3.3V or 5V mainboards like Arduino and Raspberry Pi. It’s easy to use and integrate into various applications with a small and compact body. UART mode employs standard Modbus-RTU protocol and integrates receive/send control output to allow expansion of the RS485 interface using an external RS485 transceiver.
