TBS12 Data format
To help keep the individual LoRaWAN transmissions (packets) a
manageable size, two things are done by the TBS12:
firstly, each SDI-12 measurement (combination of A
Measu Measurement number) is sent as a separate
packet
secondly, diagnostic information (battery voltage etc) is sent in a
separate packet. The transmission interval for the diagnostic data
can be set independently of that used by the logged data.
7.1. Battery data format
Format
PB:yy:mm:dd:hh:mm:ss<space>aa.bbb
Data format for battery consists of the following:
a PB header
the timestamp (
YYYY MM dd HH mm ss - year month day hour
minute second
)
the battery voltage.
7.2. Sensor data format
Sensor data is always identified with a P or parameter character and then a
second character which identifies the sensor type.
7.2.1. TBS12S, TBS12B, TBS12SM
The S, B and SM variants all support SDI-12 readings and the packets are
identified with a P for parameter then an S to indicate SDI-12
Format
PS:yy:mm:dd:hh:mm:ss<space><Index><No.
Values><space><sign>aa.bbb
The sensor (tag) data consists of the following:
the PS header
the timestamp (
YY MM dd HH mm ss - year month day hour
minute second
)
