LSN50V2-D2x LoRaWAN Waterproof, Outdoor Temperature Sensor 12 / 24
2.3 Uplink Payload
2.3.1 Payload Analyze
Normal Upload Payload:
LSN50v2-D2x use the same payload as LSn50v2 mod1, as below.
当对应端口的 DS18B20 没接或者读数出错时,会显示数据为空.下图是只接 Temp_Red 传感器.
Battery:
Check the battery voltage.
Ex1: 0x0D3B = 3387mV
Ex2: 0x0D35 = 3381mV
Temperature_RED:
This point to the RED probe in LSN50 v2-D22/D23 or the probe of LSN50v2-D20
Example:
If payload is: 0103H: (0103 & FC00 == 0), temp = 0103H /10 = 25.9 degree
If payload is: FF3FH : (FF3F & FC00 == 1) , temp = (FF3FH - 65536)/10 = -19.3 degrees.
Temperature_White:
This point to the WHITE probe in LSN50 v2-D22/D23
Example:
If payload is: 0101H: (0101 & FC00 == 0), temp = 0101H /10 = 25.7 degree
If payload is: FF3FH : (FF3F & FC00 == 1) , temp = (FF3FH - 65536)/10 = -19.3 degrees.
Temperature_Black:
This point to the BLACK probe in LSN50 v2-D23
Example:
If payload is: 00FDH: (00FD & FC00 == 0), temp = 00FD H /10 = 25.3 degree
