The latest 3 in 1 module, set the time, thermometer, voltmeter three kinds of practical functions in one,
using the DS3231 comes TCXO clock chip, with ultra-high timing accuracy and stability,
extended temperature probe, effective solution to a temperature module
temperature insufficient registration problems.
Wide supply voltage, supports 5 ~ 30V DC.
1, power supply voltage: DC5.0 ~ 30V
2, the temperature function range: -40 to 120 degrees, resolution 0.1 degrees.
3, voltmeter function Range:DC5 ~ 30V(need pure DC power supply,
24V battery is not recommended for use because of possible charging voltage is too high, burning)
