SEN136B5B

Seeed Ultrasonic Sensor Seeed ultrasonic sensor is non-contact distance measurement module, which is also compatible with electronic brick. It’s designed for easy modular project usage with industrial performance. Features Detecting range: 3cm-4m Best in 30 degree angle Electronic brick compatible interface 5VDC power supply Breadboard friendly Dual transducer Arduino library ready Specifications Supply voltage Global Current Consumption Ultrasonic Frequency Maximal Range Minimal Range Resolution Trigger Pulse Width Outline Dimension 5v 15 mA 40k Hz 400 cm 3 cm 1 cm 10 μs 43x20x15 mm Practical test of performance, Best in 30 degree angle Page 1 of 2 5/14/2010 Free Datasheet http://www.datasheet4u.net/ Sequence chart A short ultrasonic pulse is transmitted at the time 0, reflected by an object. The senor receives this signal and converts it to an electric signal. The next pulse can be transmitted when the echo is faded away. This time period is called cycle period. The recommend cycle period should be no less than 50ms. If a 10μs width trigger pulse is sent to the signal pin, the Ultrasonic module will output eight 40kHz ultrasonic signal and detect the echo back. The measured distance is proportional to the echo pulse width and can be calculated by the formula above. If no obstacle is detected, the output pin will give a 38ms high level signal.
