Treedix 3 pcs DS3231 High Precision Real Time Clock Module Board IIC Temperature Sensor Compatible with Arduino Raspberry Pi

(No ratings yet)

Key item features

Onboard DS3231 high precision clock chip, high-precision I2C real-time clock (RTC) with integrated temperature-compensated crystal oscillator (TCXO).
The module contains a battery input, which can maintain accurate timing when the main power is disconnected. The integrated crystal oscillator improves the long-term accuracy of the module.
The working format of the clock can be 24 hours or 12 hours with AM/PM indication. Provide two configurable calendar alarms and a configurable square wave output. The address and data are transferred serially via the I2C bidirectional bus.
The module also integrates a very accurate digital temperature sensor, which can be accessed through the I2C interface (Just like time). The accuracy of this temperature sensor is ±3°C.
The on-chip control circuit can realize automatic power supply detection and manage the power supply switching between the main power supply and the backup power supply(which is the low-voltage battery). If the main power supply is off, the module can continue to provide accurate timing and temperature.
