Time & Temperature display

Time & Temp. Display (TT display) can display information such as time, date, week, temperature and humidity. It is mainly used in public places such as parks, streets, roadsides, building roofs, building walls, swimming pools, schools, company entrances, hospitals, stations, service halls and other places.

Detailed Description


— Can display: year, month, day, week, lunar calendar, Saudi calendar, time, Celsius temperature, Fahrenheit temperature, relative humidity, etc.;

— Can display temperature (default with meteorological temperature box).

— 4-bit or 6-bit digital format: 88:88 or 88:88:88 or customized.

— Adopt accurate clock chip DS3231SN to give high precision of time.

— Multiple time calibration modes: GPS, NTP, IR remote control, 2-button RF remote control, communications, etc.

— Alarm clock function: support up to 20 alarm clocks; default buzzer alarm sound; settable duration of time.

— Time switch function: set the hour of turning ON/OFF display freely.

— High / low temperature alarm function: set the alarm temperature value freely; default buzzer alarm sound; settable duration of time.

— Alarm control signal output function: the output pin can be connected to an external relay for controlling other equipment.

— Powerful and flexible configuration function: free to define a personalized Time & Temp. Display.

— Power failure does not affect the accuracy of time and date.

— Customized design: different sizes and colors are available.

Some Extended Functions:

— Support extensions to display world time clock, support up to 20 time zones (need to connect more digits).

— Support connection of multiple temperature sensors. Can display multiple temperatures, such as water temperature (requires a special temperature sensor).

— Support alarm sounds from passive speakers, active speakers and music modules (requires an external speaker or voice module)

— Support hourly tell time function. The validity of this function is settable (an external voice module is required).

— Support RGB color display (the digit should be RGB color).

— Support simultaneous displaying for multiple TT displays (multiple TT displays are required networking).
