4X JSN-SR04T Waterproof Ultrasonic Module Water Proof Integrated Distance Measuring Transducer Sensor for A Beskrivelse

The 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 duration of the high level is ultrasonic from launch to return. The test distance = (high level x speed of sound (340M/S)) /2;
4. 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 for the location of the ,can be calculated distance. So constantly cycle test,that can achieve the measurement of the value of your mobile.
