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 "left", "minutes" began flashing, at this time press "right", "minutes" increased,
   and between 59 to 0 cycle.
- After adjust the "minutes",and then press the "left","hours" began flashing,at this time press "right",
  "hours" increased,and between the 23 to 0 cycle.
- After adjust the "hours",and then press the "left",jump to date adjustment,"Colon" out,"days" began flashing,
  at this time press "right","days" increased and between 1 to 31 cycle.
- Press "left" again,"months" bagan flashing,press "right","month" increased,cycle between 1 to 12.
- Press "left" again,display AC:XX,XX value is the temperature need to be corrected,the unit is ℃,
  press "right" to adjust the temperature error correction value,range from -5℃ to 5℃,
  the positive number is increased, negative is reduced.
- After that,press "left" again,enter the "dd" option,at this time display dd:X,press "right" to adjust,range from 0 to 2.
- After set the "dd" option,press "left" again,save all the data,and reture to the normal diaplay state.

2. Switch display mode

Under the state of non adjustment,press "right" 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.
