DS3231SN 3 in 1 LED Digital Clock Temperature and Voltage

Details

The latest 3 in 1 module combines three practical functions: clock, thermometer, and voltmeter, using the DS3231 clock chip with TCXO, which offers excellent accuracy and stability. It features an expandable temperature sensor, effectively solving low-temperature recording issues.

It has a wide power supply range, supporting 5 ~ 30V DC.

• Power Supply Voltage: DC5.0 ~ 30V
• Operating Temperature Range: -40 to 120 degrees, resolution 0.1 degrees.
• Voltmeter Operating Range: DC5 ~ 30V. (Clean DC power supply is required, the use of a 24V battery is not recommended due to possible high charging voltage.)
• Dimensions: 40x13mm

Usage Instructions:

You must press the left button to set the time. When the "minute" starts blinking, press the right button to increase and set the range from 00 to 59. Then, press the left button to set the "hour".

After setting the date and month, you can proceed to set the "year". Subsequently, settings for voltage and temperature values are also made.

To change the display content, press the right button. The display will alternate between time, date, temperature, and voltage.

Note: During use, the temperature sensor should be kept away from the board to avoid affecting the temperature measurement.
