TZ-TT11
Temperature & humidity Transmitter
User Guide V1.5
1. Product overview
Temperature Transmitter (hereafter referred as TT11) is with one digital temperature
/humidity transmitter, TT11 embedded GSM module, need to inset SIM card use,
built-in 3.7V/4500mAh rechargeable battery and can connect 5V external power for
charging. TT11 is with long standby time and only wakes up when it is
time to send data, or when the user operates it. Other than this, it is in sleep state so
can be used for a longer time to bring you more convenience.
