Version 3 Operating Modes
Mode 1: MODE = open / no resistor, the basic working principle:
(1) using IO port TRIG trigger range, to a minimum of 10us high letter.
(2) module automatically send 8 40khz square wave, automatically detect whether there is a signal to return;
(3) a signal to return, through the IO port ECHO output a high level, high time is the duration of ultrasound from the launch to the return time. Test distance = (high time * speed of sound (340M / s)) / 2;
(4) module is triggered after the distance measurement, if you cannot receive the echo (the reason exceeds the measured range or the probe is not on the measured object), ECHO port will automatically become low after 60MS, marking the End of measurement, whether successful or not.
(5) LED indicator, LED non-power indicator, it will receive the signal after the module will be lit, then the module is working.
Mode 2: MODE = 47KΩ resistance:
(1) Serial output format for the TTL level, that: 100MS module for the cycle of automatic output distance value, the unit is mm. Serial baud rate: 9600, n, 8,1.
(2)
After the module is powered on, it will enter the working mode directly, and the range will be carried out every 100ms within the module and one frame will be output from the pin TX, including four 8-bit data.
(3)
The frame format is:
0XFF + H_DATA + L_DATA + SUM
1.0XFF: for a frame to start the data, used to judge;
2.H_DATA: the upper 8 bits of the distance data;
3.L_DATA: the lower 8 bits of the distance data;
4.SUM: data and, for the effect of its
0XFF + H_DATA + L_DATA = SUM (only low 8)
Note: H_DATA and L_DATA synthesize 16-bit data, that is, the distance in millimeters
Mode 3: MODE = 120KΩ resistance:
(1) After the module is powered on, the module enters standby mode. The serial output format is TTL level, serial port baud rate: 9600, n, 8,1. When the RX port receives the 0X55 instruction, the module starts a ranging and outputs one frame from the pin TX with four 8-bit data.
(2)
The frame format is:
0XFF + H_DATA + L_DATA + SUM
1.0XFF: for a frame to start the data, used to judge;
2.H_DATA: the upper 8 bits of the distance data;
3.L_DATA: the lower 8 bits of the distance data; 4.SUM: data and, for the effect of its
0XFF + H_DATA + L_DATA = SUM (only low 8)
Note: H_DATA and L_DATA synthesize 16-bit data, that is, the distance in millimeters Description: The module outputs the nearest distance value in the dead zone, and outputs 0 if the module does not measure the data or is out of range. LED indicator, LED non-power indicator, it will receive the 0X55 trigger signal after the module will be lit, then the module is working.
Mode 4: MODE = 200KΩ resistance:
High level (PWM) pulse width automatic output
Under the pulse width PWM automatic output, the module automatically measures at a period of 200ms, and outputs a pulse width high level corresponding to the distance after the measurement. Calculating distance mode reference mode 1
Mode 5: MODE = 360KΩ resistance:
low power consumption (PWM) high level pulse width controlled output
In low-power mode, the module’s shut-down watch dog is disabled. This module is suitable for battery-powered users. The static power consumption is less than 70UA. The working distance measurement method is the same as mode 1
Mode 6: MODE = 470KΩ resistance:
switch output
The module will set a threshold value at the factory, the default is 1.5 meters. The module performs ranging every 200ms. When the detected distance value of the target is less than the set threshold, the Echo pin outputs a high level. The currently detected distance value is greater than the set threshold, and the Echo pin outputs a low power. In order to improve the stability, the factory defaults that the distance detected by the target for two consecutive times is less than the set threshold. Signal, no driving ability. Transistor drive relays should be added during application.
