Sensor using ultrasound for distance measurement.
Ultrasonic sensor operating in the range from 2 cm to 200 cm with special bracket for mounting. It is powered with the voltage of 5 V. The output is a signal whose duration is proportional to the measured distance.
Ultrasonic sensor from the DFRobot working in the range of up to 7.5 m. It is powered with the voltage from 3.0 V to 5.5 V. The average supply current is 5 mA, and in the rest mode -14 uA. The sensor also has a temperature compensation.
Ultrasonic sensor from DFRobot operating in the range from 5 cm to 500 cm. It is powered with the voltage from 3.3 V to 5 V. Communication is via serial interface UART (RX, TX) and has an analog and frequency output as well as compensation temperature.
Waterproof ultrasonic sensor operating in the range from 20 cm to 450 cm. It is powered with voltage of 5 V. The output is a signal whose duration is proportional to the measured distance. The sensor is compatible with popular sensor HC-SR04, which means that the sample programs and libraries will work correctly for both sensors.
Kit for self-assembly enabling the addition of ultrasonic scanner function to robot. The sensor is able to scan an area of 120 ° in the range from 10 cm to 400 cm. It consists of a servo, ultrasonic distance sensor and mounting bracket.
Module with ultrasonic sensor URM09 and three measurement ranges to choose from 2 to 150 / 300 / 500 cm. It also allows for a temperature measurement. Supply voltage is from 3.3 V to 5.5 V. The measurement frequency can reach up to 50 Hz. It communicates using the I2C interface.
Ultrasonic sensor operating in the range from 2 cm to 400 cm. It is powered with voltage of 5 V. The output is a signal, duration of which is proportional to the measured distance. Unlike the HC-SR04, it has one additional empty pin.
