GY-MLX90615 MLX90615 Digitale Infrarossi Temperatura Sensore

Product Description

GY-MLX90615 MLX90615 Digital Infrared Temperature Sensor

Serial port to send the command byte:

(1), serial communications parameters (baud default value 115200 bps, can be set by software)

Baud Rate: 9600 bps parity bit: N Data bits: 8 Stop bits: 1

Baud rate: 115200 bps parity bit: N Data bits: 8 Stop bits: 1

(2), the module input commands sent by an external controller to the GY-MCU90615 module (hex)

1, header: 0xa5

Instruction format: header + command + checksum (8bit) (such as automatic read temperature command = 0xA5 + 0x45 + 0xEA)

2, the command instruction:

Continuous output instruction:

0xA5 + 0x45 + 0xEA —————- temperature data (module returns data type 0x45)

Query output instructions:

0xA5 + 0x15 + 0xBA ————— temperature data (module returns data type 0x45)

🙁 Configuration directives take effect after power-down restart)

Baud rate configurations:

0xA5 + 0xAE + 0x53 ————— 9600

0xA5 + 0xAF + 0x54 ————— 115200 (default)

Is powered automatically send temperature data configuration:

0xA5 + 0x51 + 0xF6 ————— output temperature data automatically after power

0xA5 + 0x52 + 0xF7 ————— not automatically after power output temperature data (default)

letter of agreement

Serial port to receive:

(1), serial communications parameters (baud default value 115200 bps, can be set by software)

Baud Rate: 9600 bps parity bit: N Data bits: 8 Stop bits: 1

Baud rate: 115200 bps parity bit: N Data bits: 8 Stop bits: 1

(2), the module output format, each frame contains nine bytes (hex):

Byte0: 0x5A Preamble Flags

Byte1: 0x5A Preamble Flags

Byte2: 0X45 The frame data types (0X45: temperature data)

Byte3: 0x04 amount of data (data 2 the following four groups, for example)

Byte4: 0x00 ~ 0xFF Data 1 high 8

Byte5: 0x00 ~ 0xFF Data 1 low 8

Byte6: 0x00 ~ 0xFF Data 2 high 8

Byte8: 0x00 ~ 0xFF checksum (data accumulation and front, leaving only the lower 8 bits)

(3), data calculation method

Temperature calculation method:

High temperature = 8 << 8 | Low 8 (results for the actual angle multiplied by 100)

Example: Send command: A5 45 EA, received a data:

<5A- 5A- 45- 04- 0C- 78- 0D- 19- A7>

Represent TO (signed 16bit, represents the target temperature): TO = 0x0C78 / 100 = 31.92 ℃

Represents TA (signed 16bit, represents the ambient temperature): TO = 0x0D19 / 100 = 33.53  ℃
