Temperature&humidity Transmitter
User Guide V2.1
1. Product overview
The temperature and humidity transmitter (hereafter referred as TT18) is with built-in
temperature & humidity sensor and GSM module which needs to inset SIM card use.
There are three modes of TT18, turn on, turn off and flight mode. It only wakes up
when it is time to send data or when the use operates it. Otherwise, it is in sleep status.
So that it can be used for a longer time to bring you more convenience.
TT18 can collect the surrounding temperature and humidity with high precision
quickly and transmit them to the server through GPRS. It is widely used in cold chain
logistics, medicine, transportation and other industries.
When using, hang the wall, it can react the peripheral temperature very quickly.

7. Use the GPRS function
You can through the following way to configure the machine :
1. The configuration software
2. SMS
3. The server (the machine must enable ACK function and the server response ACK before
sending you need to set up instructions, otherwise the machine will immediately into sleep. The
default machine already have opened the ACK function, the machine once every send GPRS data
to the server, the server must respond @ACK, Packet index# to the machine, then the machine
will continue to send next GPRS data to the server).
Notes:
1.We have set up all the default command, you only need to insert a GPRS network SIM card,
then the device will send data to our server. (Please kindly refer to the common list below if you’d
like to know the default settings)
2. If you want change the setting, 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

Tzonedigital_TT18 V2.1 Apr27, 2017
Username:
Password:
Step2: Set the server’s IP & PORT
Format: *$$$$$$,015,1,IP,PORT#
For example: *000000,015,1,gateway.gotracking.net,18801#
gateway.gotracking.net is our server’s domain name,18801 is the port.
If client have the server by himself, please make sure the IP and port is correct.
After you send the command of SMS to device, it will reply to your mobile phone
Receive:’015’OK
000000,015,1,gateway.gotracking.net,18801#
If you send the command by USB to device, the serial port tool will shows:
CMD bytes: 2B
*000000,015,1,gateway.gotracking.net,18801#
ComdType:015(SETIPANDPORT)
Mode:01
IP/Domain Name:gateway.gotracking.net
Port:18801
Step3: Set GPRS time interval
Format: *$$$$$$,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

9. Instruction
With the battery in TT18, press the button for 5s, machine running,when TT18
completes initialization, it will go to 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:
1. Please don’t connect the USB cable when the device is sending data to server,
because maybe will affect the data sending and the temperature higher than the actual
temperature
2. Please set the RTC time when turn on the device, otherwise the machine for the
initial time. If sending the data to our server, when our server get yours device data,
the RTC time will auto update. If you have your own server, you can make the
following settings can change the device RTC time .
The server send to device format:
