DIY Creative Microcontroller Clock Module with Temperature Date Voltage Measurement

DIY Creative Microcontroller Clock Module With Temperature Date Voltage Measurement
Feature:
1. Base on microcontroller, ultra slim and small design,50*19*14mm
2. Wide working voltage support,3.8~30V (note:the lower voltage ,the lower brightness and lower power consumption)
3. Highlight digital tube,high brightness,better visibility,can be seen clearly in the relatively bright environment.
4. Total 5 display mode,
①Display only time
②Display only date
③Display only temperature
④Display only voltage
⑤Interchanging display time,temperature and voltage
5. With Temperature display function,
Display Range: -30℃~60℃
Minimum Resolution: 0.1℃
And also with setting function of temperature error correction,
Setting Range: -5℃~5℃
6. With 24 hours timing error correction setting function,can be set every 24 hours to correct error once,
Setting Range: -9~9 seconds (note:in order to make the function effort,have to 24 hours of continuous power supply)
7. Use DS1302,come with CR1220 backup battery.
Instructions:
1. adjust the time, date, temperature error correction, 24 hours error correction, DD options
– Under normal use, press the inchleftinch, inchminutesinch began flashing, at this time press inchrightinch, inchminutesinch increased,
and between 59 to 0 cycle.
– After adjust the inchminutesinch,and then press the inchleftinch,inchhoursinch began flashing,at this time press inchrightinch,
inchhoursinch increased,and between the 23 to 0 cycle.
– After adjust the inchhoursinch,and then press the inchleftinch,jump to date adjustment,inchColoninch out,inchdaysinch began flashing,
at this time press inchrightinch,inchdaysinch increased and between 1 to 31 cycle.
– Press inchleftinch again,inchmonthsinch bagan flashing,press inchrightinch,inchmonthinch increased,cycle between 1 to 12.
– Press inchleftinch again,display AC:XX,XX value is the temperature need to be corrected,the unit is ℃,
press inchrightinch to adjust the temperature error correction value,range from -5℃ to 5℃,
the positive number is increased, negative is reduced.
– After that,press inchleftinch again,enter the inchddinch option,at this time display dd:X,press inchrightinch to adjust,range from 0 to 2.
– After set the inchddinch option,press inchleftinch again,save all the data,and reture to the normal diaplay state.
2. Switch display mode
Under the state of non adjustment,press inchrightinch to switch the display mode,from ① show only time →② only date
→③ only temperature →④ only voltage →⑤ time,temperature and voltage display in turn,interval of about 4 seconds
(Note:in alternate display mode,Can choose whether to display temperature or voltage by using the DD option.)
dd:0 state display time + temperature + voltage.
dd:1 state display time + voltage.
dd:2 state diaplay time + temperature.
Package Included:
1 X Microcontroller Clock
