JSN-04 Ultrasonic Sensor

The JSN-SR04T Version 2 supports up to 3 differnt modes.

Mode 2: R27 = 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: R27 = 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.
