JSN-SR04T Waterproof Ultrasonic Distance SensorWaterproof Ultrasonic Distance Sensor gives distance value using ultrasonic waves. JSN-SR04T Ultrasonic Sensor can be read using any microcontroller board like ARDUINO UNO, ARDUINO DUE, ARDUINO PRO MINI, ARDUINO NANO, AND OTHER DEVELOPMENT PLATFORMS.
(1) using IO port TRIG trigger location, to the high-level signal of at least 10us; the module automatically sends 8 40KHz Fang Bo, automatic detecting whether a signal return; 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 a 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.
