Product Descriptions
Supply voltage: 3-5V
Power supply current: 7mA
Wiring:
Red... VCC
Black... GND
Yellow... RC (Half Port UART TTL-Rx/I2C.. SCL)
Self color... TD (half port UART TTL Tx/I2C.. SCL)
The module defaults to serial UART mode and automatically outputs data. When the PS solder joints on the PCB are soldered, it is in I2C mode.
1. Module internal registers:
| 0x00(Reading and writing) | 器件 ID 地址 Device ID address | 1~254;0为广播地址;默认为ID:0xA4，与8位 ⅡC 地址相同，所以该地址必须为2的倍数。 1~254; 0 is the broadcast address; The default ID is 0xA4, which is the same as the 8-bit IIC address, so this address must be a multiple of 2. |
| 0x01(Reading and writing) | 波特率设置 Baud rate setting | 0-7:2400 4800 9600 19200,38400,57600.115200,230400 |
| 0x02(Reading and writing) | 更新速率 Update rate | 0: 1hz;1:2hz;2:5hz;3:10hz |
| 0x03(Reading and writing) | 输出模式 Output mode | 0:连续输出;1:查询输出 0: Continuous output; 1: Query output |
| 0x04(Reading and writing) | 输出格式 Ooutput format | 0:十六进制;1:字符; 0: Hexadecimal system; 1: Characters; |
| 0x05(Reading and writing) | 保存设置 Save Settings | 0x55:保存当前配置;0xAA:恢复出厂设置 0x55: Save current configuration; 0xAA: Factory reset |
| 0x06(Reading and writing) | TO off温度偏移 TO off temperature offset | 0-255，默认值100=0偏移，TO补偿= (TO_off-100)/10 0-255, default value 100=0 offset, TO compensation= (TO_off-100)/10" |
| 0x07(Reading and writing) | E 发射率 E emissivity | 1~100(对应 0.01~1.00) |
| 0x08(Read) | TO(目标温度)高8位 TO (target temperature) high by 8 digits | 0~255 |
| 0x09(Read) | TO(目标温度)低8位 TO (target temperature) is 8 digits lower | 0~255 |
| 0x0a(Read) | TA(环境温度)高8位 TA (ambient temperature) high by 8 digits | 0~255 |
| 0x0b(Read) | TA(环境温度)低8位 TA (ambient temperature) is 8 digits lower | 0~255 |
| 0x0c(Read) | BO高8位 BO high 8 digits | 0~255 额温转换体温值高8位 0-255 forehead temperature conversion with a body temperature value 8 digits higher |
| 0x0d(Read) | BO低8位 BO low 8 digits | 0~255 额温转换体温值高8位 0-255 forehead temperature conversion with a body temperature value 8 digits higher |

| 地址 Address | 功能码 Function code | 数据 Data | 校验和 Checksum |
| 1 byte | 1 byte | N byte | 前字节校验和低8位 The lower 8 bits of the first byte checksum |
2. Module support function code:
| 写单个寄存器 Preset Single Register | 0x06 |
| 读寄存器 Read Register | 0x03 |
3. Module response time
| 波特率=9600 Baud rate=9600 | 约为 10ms |
| 波特率=115200 Baud rate=115200 | 约为 1ms |
IIC function:
This function requires welding PS solder joints. The IIC address is the value of the 00 register, with a default of 4. The IIC rate needs to be less than 400K.
The number of registers written in a single module is 1. Write the timing sequence as follows, which requires more than 4us of time after sending the device address
| Start | Address | ACK | reg | ACK | Data | ACK | Stop |
| 起始 Start | 0XA4 | 模块 Module | 0x07 | 模块 Module | 0x57 | 模块 Module | 结束 End |
