Product Features

1.5 different display modes:

(1) Show only time (2) Show only date (3) Show only temperature (4) (5) Display only voltage, temperature alternately display

2. Use the DS1302 clock module to provide accurate time. You can set or adjust the time. When the power failure, because the CR927 backup battery.

3. The module can be used as a voltmeter to measure the voltage (input voltage is less than or equal to 7 v).

4. The module can measure the temperature, and its working principle.

5. This module is small and delicate takes up very little space. (Length: 40 mm Width: 13 mm Height: 17 mm)

6. This module can be clearly displayed in bright places because of the good digital tube.

7.24 hours Timing error correction function setting.
