URM13 Ultrasonic Sensor
106 units will be available shortly.
DFRobot URM13 is an ultrasonic ranging sensor with open single-probe. It supports TRIG Pulse-triggered ranging (SR04 compatible), UART, and I2C communication protocols, which brings more possibilities for actual using scenarios. With a small and compact body, the sensor works well with 3.3V or 5V mainboards like Arduino and Raspberry Pi, easy to use and integrate into various applications. Besides, the UART mode employs standard Modbus-RTU protocol and integrates receive/send control output to allow users to easily expand the RS485 interface using an external RS485 transceiver.
The URM13 is positioned to be a professional and advanced ultrasonic sensor. The integration of a new precision circuit design and smart detection algorithms on the sensor makes it much smaller and lighter, while still maintaining excellent sensitivity. At the same time, the URM13 sensor is able to automatically detect ambient and electrical noise, and complete the dynamic adjustment and calibration of sensor parameters in real-time, which ensures its stable performance in various complex application scenarios.
