Since 2008, DFRobot is dedicated to provide outstanding sensor solutions to more than 200 countries and regions all over the world. And this series of products have been widely applied to various industries. Among them, the URM series of ultrasonic sensors demonstrate excellent performance in ease of use, low-cost maintenance, quick and high accuracy measurement in multiple applications. 

Until now, DFRobot own 6 categories ultrasonic sensors, as shown below:

1.URM37 Ultrasonic Sensor

Product: URM37 Ultrasonic Sensor (SKU: SEN0001)

Brief Introduction: It has rich interfaces and offers various output: analog output, switch, serial (TTL and RS232 level optional), PWM and so on. The module can be used to measure the rotation angle of the servo. Connected with an external servo, it changes into a spatial ultrasonic scanner.

2.URM06 Ultrasonic Sensor

Product:

URM06-RS485 Ultrasonic Sensor (SKU: SEN0149)

URM06-UART Ultrasonic Sensor (SKU: SEN0150)

URM06-PULSE Ultrasonic Sensor (SKU: SEN0151)

URM06-ANALOG Ultrasonic Sensor (SKU: SEN0152)

Brief Introduction: URM06 series ultrasonic sensors have very small detection angles and high detection sensitivity. They perform excellently in the target detection, especially in narrow spaces. And its integrated structure design facilitates the secondary integration and equipment assembly.

3.URM07-UART Ultrasonic Sensor

Product: URM07-UART Ultrasonic Sensor (SKU: SEN0153) 

Brief Introduction: The small URM07 series are the best choices for lightweight applications. With relatively small size and concise hardware design, it is more suitable for applications that are sensitive to power consumption and quality, like micro air vehicles (MAV) and applications powered by the battery.

4.URM08-RS485 Ultrasonic Sensor

Product: URM08-RS485 Ultrasonic Sensor (SKU: SEN0246)

Brief Introduction: URM08 series ultrasonic sensors have relatively large detection angles and high detection sensitivity. It is suitable for obstacle detection and obstacle avoidance applications in the wide area, such as small transport vehicles, trolleys, forklift auxiliary barrier avoidance radar equipment. The all-metal housing is designed to maintain stable detection performance even under complex electromagnetic interference.

5.URM09-I2C Ultrasonic Sensor

Product: URM09-I2C Ultrasonic Sensor (SKU: SEN0304)

Brief Introduction: The URM09 I²C version has a customizable range/sensitivity/measurement cycle configuration that can be applied to different scenarios. The standard I²C bus communication interface can realize the connection of hundreds of sensors.

Product: URM09-ANALOG Ultrasonic Sensor (SKU: SEN0307)

Brief Introduction: The simulation version of the URM09 working operation is based on the real-time automatic ranging. It can convert the detected distance information into an analog voltage output in real time, can control the peripheral circuit solely through the output voltage, and can collect sensor data through various ADC interfaces of kinds of main controls.

6.URM12 Ultrasonic Sensor

Product: URM12 Ultrasonic Sensor (SKU: SEN0310)

Brief Introduction: The URM12 series ultrasonic sensors offer excellent all-round protection from dust and environmental pollution. Its fully shielded interior circuit design, excellent detection sensitivity and very small detection angle enable a stable directional non-contact detection in indoor or outdoor environments.
