40Khz Waterproof Non-Contact Distance Ranging Ultrasonic Sensor Module Detector
Non-contact Ultrasonic Ranging ModuleFeatures:
High performance non-contact ultrasonic distance sensor module with 4 pin: 5V, RX(Trig), TX(Echo), GND.
Water-proof.
Low voltage and low power consumption.
Small dead zone.
30cm to 3m wide detecting range.
It can be applied for measuring the distance between objects, waterproof ranging occasions, programmable car obstacle avoidance, robot obstacle avoidance, security and industrial control, etc.Note:
Please make sure that there is no object within the minimum detecting distance, i.e. 30cm. Or the measuring result will be inaccurate.Specifications:

6, artificial intelligence, and researchThe basic working principle:(1) using IO port TRIG trigger location, to the high level signal of at least 10us;
(2) module automatically sends 8 40KHz Fang Bo, automatic detecting whether a signal return;
(3) a signal return, a high level is output through the IO port ECHO, the time duration of the high level is
ultrasonic from launch to return. The test distance = (high level time * speed of sound (340M/S)) /2;
This module uses the simple method, a control port with a 10US above high level, can wait for high level
output at the receiving port. An output can drive the timer, when this port is low can read the timer value,
this time for the location of the time, can be calculated distance. So constantly cycle test, that can achieve
the measurement of the value of your mobile.Package Included:1 x Ultrasonic Module Distance Measuring Transducer Sensor Waterproof40Khz Ultrasonic SensorWorking voltage:DC 5V
