Features:OOTDTY1, on the basis of the single microcomputer, ul-small ul-thin design, long: 50 mm wide: 19 mm thick: 14 mm2,wideWorking support, can work in4.2V--30V And with the function of the meter, the size of the input can be measured.3, the ofHigh bright tube , high brightne, more visibility, in a relatively bright envment also can see4, a total of 5 kinds of display(1) only show the for time (2) show only the date (3) only (4) show only the temperature (5) show the temperature for time, temperature, alternatingNote:in alternating display can choose whether to display temperature DD through the degree option Or dd:0 display for time + temperature.Dd:1 degree+ display for time + voltage.Dd:2 display for time + temperature degree5,Temperature display Function, display -30 ~ 60Minimum resolution 0.1 degree And with the temperature error correction function, set the of -5 ~ 5 degree6, with 24 hours timing error correction setting function, set every 24 hours and correction of an error, setting 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 DS1302 and comes with a backup CR1220, off for time to go. And the of 5ppm in high crystal oscillator, accurate timing, small errorSpecifications:Size:long: 50 mm wide: 19 mm thick: 14 mmWorkingColor:Green,,Red (for your choice)5 kinds of displayTemperaturer esolution:0.1℃24 hours timing error correction setting functionfor Time :DS1302Package include:1pc Electronic CloModule
