Cable Length 15m 5m
Protection Grade IP67
SER510R/T Communication Protocol
1. SER510R/T adopts standard DB9 interface, with serial asynchronous communication
mode, baud rate is 9600, start bits is 1, data bits is 8, 1 stop bits is 1, no parity bit.
Pin Description: 2------->TXD
3<-------RXD
5<-----> GND
7------->VDD+5V
2. Data protocols, the sensor will send the brightness and temperature that collected
every second, the formats are as follows:
Header (12 bytes) Effective
Brightness
Brightness Effective
Temperature
Temperature Checksum
E5 B2 41 FF 02 00 0A
00 73 6E 72 3A
1 byte 2 bytes 1 byte 2 bytes 2 bytes
Header is for fixed 12 bytes
Effective Brightness: 01: Effective brightness
00: Invalid brightness
Brightness: High byte front, low byte behind, attenuation coefficient of the cover is about
3.3.
Maximum value of brightness: FFFE, and FFFF means brightness is overflow.
The brightness value of the sensors return multiplied by 3.3 is the current unique
degree of brightness (lx).
Effective Temperature: 01: Effective temperature
00: Invalid temperature
Temperature: High byte front, low byte behind. Integer part of temperature is divide the
value by 10, and the decimal part is remainder. The highest bit is 1 when the temperature
is below zero, and the unit of the temperature is Celsius degrees.
Checksum: Including all the header bytes plus 1.
