Specifications

1) Content of communication protocol
 Data format：
 Content description：
a. Data head: 4ms for high level and 8ms for low level;
b. Interval code (high level): 480us;
c. Data (low level): 0 - > 480us, 1 - > 1.44ms; 32 bit data in total;
d. Data transmission sequence: first send data header, then interval code, and then
send data code, each bit of data is followed by an interval code, and the data is
sent in sequence from high to low;
 Frame format: start code + data + check sum, 4 bytes of data in total
a. See data protocol for function and format;
b. Check sum: 1 byte, starting code + function + cumulative sum of data. Only 8 bits
are reserved if more than 8 bits;

Data packet
：
a. Byte0：0x4C
b. Byte1：bit7->The sitting indication ,‘1’ is the sitting state and ‘0’ is the
off seat state
bit6->Automatic flip ,‘1’ is on, ‘0’ is off; it is on by default and restored
by
default after power failure
bit5->air gesture1 is on, ‘0’ is off; it is on by default and restored by default
after power failure
bit4-2->reserved
Bit1->Seat ring status,‘1’ means that the seat ring is open, and the‘0’ position
seat ring is closed
Bit0->Cover plate status,‘1’ is the cover plate open, ‘0’ is the cover plate
closed
c. Byte2：Duty cycle, used to adjust the sensing range（5, 10, 14, 20, 28, 38, 50,
65, 80, 100）
d. Byte3：Check sum（The cumulative sum of byte0-byte2, with 8 bits reserved）
 Special command word：
After receiving this data packet, turn off the microwave induction, do not output the
induction signal, and receive any other signal to resume work.
a. Byte0：0x4C
b. Byte1：0xB0
c. Byte2：0xBF
d. Byte3：Check sum
