Sensor using ultrasound for distance measurement.
Ultrasonic transducer operating in the range from 2 cm to 200 cm with special fastener for mounting. A power voltage of 5 V. the Output is a signal whose duration is proportional to the measured distance.
Ultrasonic transducer brand DFRobot current up to 7.5 m. Supply voltage from 3.0 V to 5.5 V. the Average supply current is 5 mA, and in standby mode-14 uA. The sensor also has a temperature compensation.
Ultrasonic transducer brand DFRobot operating in the range from 5 cm to 500 cm Power voltage from 3.3 V to 5 V. Communication via serial interface UART (RX, TX) and has an analog output and use, 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.
Ultrasonic sensor operating in the range from 3 cm to 350 cm. It is powered with voltage of 5 V. The output is a signal, duration of which is proportional to the measured distance. The kit includes a cable adapted to Seeedstudio Base Shield v2.0.
