6. artificial intelligence, and research

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 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.

uxcell 1-10mm Capacitance Proximity Sensor Switch Detector NPN NO DC 6-36V 300mA 3-Wire LJC18A3-H-Z/BX Lowest new price: $13.49
List price: $13.49
Brand: uxcell
Model: a18031200ux0195

Description:

Note: 1. The Optimum voltage range is 6~36VDC.
         2. It is recommended that the actual detection distance is less than 70% of the detection distance on the name plate.
         3.When wiring, do not energized, strictly according to the wiring diagram.

NOT ALL MATERIAL ARE SUBJECT TO THE 10MM DETECTING RANGE.
3 factors that affect the function of the sensor:

1. Material density. Most of  plastic material is not detectable by a capacitive proximity sensor at a proper distance, sometimes becasue the density is low , sometimes because the plastic is too thin, for example, if you detect an empty 1mm thick plastic bottle, the detecting distance may be less than 2mm , if you fill the bottle with water ,then the detection distance could be longer than 5mm.
2. The Sensitivity, when the sensor cannot work, there is a sensitivity-adjustment screw on the back of the sensor, you can turn it clockwise with a flat head screwdriver  to increase the sensitivity of the sensor 
3. Load Current . High output current can result in prodct failue, Inductive load (for instance, motors which draw high current when started) is not allowed  to be directly connected with this sensor, because this sensor can only provide 300mA current for the load , you can use this sensor to provide a low level signal for a PLC which requires very little current ,or you can control a small relay that requires a coil current less than 100mA.

Detecting Distance is adjustable. Turn clockwise to increase, counterclockwise to decrease. Range:1-10mm.
