Application of JSN SR04T Water Proof Ultrasonic Sensor Module :
- It is used in horizontal distance measurement.
- It is used as obstacle avoidance or automatic control.
- It is used for object approaches, and there is a perceived.
- It is used for traffic control.
- It is used in artificial intelligence and research.
Basic Working Principle:
- Firstly, using the IO port TRIG trigger location, for the high-level signal of at least 10us.
- Then the module automatically sends 8 40 Khz fang Bo, and it automatically detecting whether signal return.
- Then signal return, a high level is output through the IO port ECHO.
- Then ultrasonic from launch to return.
- The distance will be calculated = (high-level time x speed of sound (340M/S))/2.
- It has an output at the receiving port. An output can drive the timer when this port is low can read the timer value.
- At the time for the location of the time can be calculated distance.
