DS3231 Real Time Clock Module for Raspberry Pi Arduino โมดูลนาฬิกา มีเซนเซอร์อุณหภูมิในตัว พร้อมแบตเตอร์รี่

DS3231 Real Time Clock Module for Raspberry Pi โมดูลนาฬิกา Real Time Clock ใช้ไอซีเบอร์ DS3231 มีเซนเซอร์อุณหภูมิในตัว พร้อมแบตเตอร์รี่ The DS3231 is a low-cost, extremely accurate I2C real- time clock (RTC) with an integrated temperature- compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains accu- rate timekeeping when main power to the device is inter- rupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line. The DS3231 is available in commercial and industrial temperature ranges, and is offered in a 16-pin, 300-mil SO package. คุณสมบัติ DS3231 Real Time Clock Module for Raspberry Pi Accuracy ±2ppm from 0°C to +40°C Accuracy ±3.5ppm from -40°C to +85°C Battery Backup Input for Continuous Timekeeping Operating Temperature Ranges - Commercial: 0°C to +70°C, Industrial: -40°C to +85°C Low-Power Consumption Real-Time Clock Counts Seconds, Minutes, Hours, Day, Date, Month, and Year with Leap Year Compensation Valid Up to 2100 Two Time-of-Day Alarms Programmable Square-Wave Output Fast (400kHz) I2C Interface 3.3V Operation Digital Temp Sensor Output: ±3°C Accuracy Register for Aging Trim RST Output/Pushbutton Reset Debounce Input Underwriters Laboratories (UL) Recognized
