Temperature&humidity Transmitter
User Guide V1.5
1. Product overview
Temperature Transmitter (hereafter referred as TT18) built-in temperature
/humidity transmitter and GSM module, need to inset SIM card use.TT18 is with long
standby time and only wakes up when it is time to send data, or when the use operates
it. Other than this, it is in sleep state so can be used for a longer time to bring you
more convenience.
Temperature Transmitter can collect high-precision temperature/humidity quickly, and
then transmit to the server through GPRS. It is widely used in cold chain logistics,
medicine, transportation and other industries.

6. Use the GPRS function
Notes:
You can set it via SMS or use the same command via serial port tool.
Step1: Set the APN (Access Point Name)
Different network of provider have the different APN at every country, if you
don't know, please refer to the attachment.
Format: *$$$$$$,011,APN,Username,Password#
Notes: The username and password could to be null.
For example: *000000,011,cmnet,,#
Explication: The China Mobile’s APN is “cmnet”, and the username and
password are empty.
After you send the command of SMS to device, it will reply to your mobile phone:
Receive:’011’OK
*000000,011,cmnet,,#
If you send the command of USB to device, the serial port tool will shows:
CMD bytes: 14
*000000,011,cmnet,,#
ComdType:011(SETAPN)
APNnumber:cmnet
Username:
Password:
Step2: Set the server’s IP & PORT
Format: *$$$$$$,015,1,IP,PORT#
For example: *000000,015,1,gateway.gotracking.net,54929#
gateway.gotracking.net is our server’s domain name,54929 is the port.
If client have the server by himself, please make sure the IP and port is correct.

Tzonedigital_TT18 V1.4 June9, 2016
After you send the command of SMS to device, it will reply to your mobile phone
Receive:’015’OK
000000,015,1,gateway.gotracking.net,54929#
If you send the command by USB to device, the serial port tool will shows:
CMD bytes: 2B
*000000,015,1,gateway.gotracking.net,54929#
ComdType:015(SETIPANDPORT)
Mode:01
IP/Domain Name:gateway.gotracking.net
Port:54929
Step3: Set GPRS time interval
Format: *$$$$$$,018,X#
X: the time interval (unit is min),
For example:*000000,018,1#
The device will send GPRS every1 minute and no times limit.
After you send the command of SMS to device, it will reply to your mobile phone:
Receive:’018’OK
*000000,018,1#
If you send the command of USB to device, the serial port tool will shows:
CMD bytes: 0E
*000000,018,1#
ComdType:018(SetGpreInternal)
Interval:1

3
Set the high/low temperature and
humidity alarm function
When the TT11 high/low
temperature and humidity,
TT11 will always send high/low
temperature and humidity alarm
GPRS data to the Preset Server.
the machine can send data
according to the time interval
you have set(003 has priority to
004)
*$$$$$$,003,A,B,C,D,X#
A=[-40~125],high-temperature
threshold(unit:℃,default:100)
B=[-40~125],low-temperature
threshold(unit:℃,default:-20)
A must be bigger than B
if Temperatures exceed [A, B],it
will send alarm data
C=[0~100],high-humidity
threshold(unit:%,default:80)
D=[0~100],low-humidity
threshold(unit:%,default:20)
C must be bigger than D
if Humidity exceed [A, B],it will
send alarm data
X=[1,60],TT18 more than
threshold change into Xmin send a
GPRS data(unit:min,default:1)
4
Set low power alarm
When the TT18 voltage is lower
than the preset value,
TT18 will send one lower power
alarm GPRS data to the Preset
Server.
the machine can send data
according to the time interval
you have set
*$$$$$$,004,X,Y#
X is the low power alarm voltage,
eg: 3.8v,X=380(default:350)
Y=[1~60] Y is the Low power to
send data interval time(unit:min,
default:60, 0 is don’t send data )
For example：
*$$$$$$,004,380,10#
When the battery voltage is lower
than 3.8 V, 10 minutes to send a
GPRS data
5
Set RTC time
*$$$$$$,006,year,mounth,day,hour
,minute,second#
Set the device RTC time .
For example：
*000000,006,16,01,11,10,46,30#
Year:16
Mounth:1
Day:11
Hour:10
Minute:46
Second:30

8. Instruction
With the battery in TT18 , turn on the switch , machine running,when TT18 completes
initialization and sends the first data, it will sleep, Most of the time TT18 is in sleep
mode, with only interval time data, only when connected with serial port tool for
configuration,or it is called / receives SMS command, will it wake up. After this, it
goes into sleep mode again, thus it can work for longer time.
Note:
Please set the RTC time when turn on the device, otherwise the machine for the initial
time.(if send data to ours server, when ours server get yours device data, the RTC time
will auto update).
