12V 5-24V Electronic Voltmeter Thermometer Clock for Car Auto LED Monitor Module

Features:

1, on the basis of the single chip microcomputer, ultra-small ultra-thin design, long: 50 mm wide: 19 mm thick: 14 mm

2,wideWorking voltage support, can work in4.2V--30V And with the function of the voltage meter, the size of the input voltage can be measured.

3, the use ofHigh bright tube , high brightness, more visibility, in a relatively bright environment also can see

4, a total of 5 kinds of display mode,

(1) only show the time (2) show only the date (3) only voltage (4) show only the temperature (5) show the temperature time, temperature, alternating voltage (Note: in alternating display mode, can choose whether to display temperature DD through the degree option Or voltage, dd:0 state display time + temperature.Dd:1 voltage degree+ state display time + voltage.Dd:2 state display time + temperature degree )

5,Temperature display Function, display range -30 ~ 60Minimum resolution 0.1 degree And with the temperature error correction function, set the range of -5 ~ 5 degree

6, with 24 hours timing error correction setting function, set every 24 hours and correction of an error, setting range 9 to 9 seconds. (Note: to give effect to the function, must be 24 hours of continuous power supply is every 24 hours to correction of an error)

7. With the timing of the chip DS1302 and comes with a battery backup CR1220, off time to go. And the use of 5ppm in high precision crystal oscillator, accurate timing, small error
