## Description

This item is a high performance, cost-effective ,non-contact distance measurement module, and with temperature compensation;is calculated by distance by 340 m / sec; measuring range of 0.02 to 5.00m, accuracy 1cm, measured with the measured object without direct contact, can clearly show a stable measurement result.

**Instructions for use:**

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 150ms.
 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 65ms high level signal.
