• DS3231 Realaus laiko modulis + temperatūros jutiklis

    • 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,  disconnect the main power supply and maintains accurate timekeeping.
      • Integrated oscillator improve long-term accuracy  of the device and reduces the number of components of the production line.
      • DS3231 available in commercial and industrial  temperature ranges, using a 16-pin 300mil SO package.
      • RTC maintains seconds, minutes, hours, day, date,  month, and year information. Less than 31 days of the month, the end date will  be automatically adjusted, including corrections for leap year.
      • Clock operates in either the 24 hours or band / AM  / PM indication of the 12-hour format. Provides two configurable alarm clock and  a calendar can be set to a square wave output.
      • Address and data are transferred serially through  an I2C bidirectional bus.
      • A precision temperature-compensated voltage  reference and comparator circuit monitors the status of VCC to detect power  failures, provide a reset output, and if necessary, automatically switch to the  backup power supply. 
      • /RST pin is monitored as generating μP reset  manually.
      • Save time and high precision addition, DS3231 also  has some other features that extend the system host of additional features and a  range of options.
      • The device integrates a very precise digital  temperature sensor, through the I2C * interface to access it (as the same time).
      • Temperature sensor accuracy is ± 3 ° C. On-chip  power supply control circuit can automatically detect and manage the main and  standby power (i.e., low-voltage battery) to switch between the power supply.
      • If the main power failure, the device can continue  to provide accurate timing and temperature, performance is not affected.
      • When the main power re-power or voltage value  returns to within the allowable range, the on-chip reset function can be used to  restart the system microprocessor.

      • Size: 38mm (length) * 22mm (W) * 14mm (height)
      • Operating voltage :3.3 - 5 .5 V
      • clock chip: high-precision clock chip DS3231
      • Clock Accuracy :0-40 Degree range, the accuracy 2ppm,  the error was about 1 minute
      • Calendar alarm clock with two
      • Programmable square-wave output
      • Real time clock generator seconds, minutes, hours,  day, date, month and year timing and provide valid until the year 2100 leap year  compensation
      • Chip temperature sensor comes with an accuracy of  ± 3 Degree
      • Memory chips: AT24C32 (storage capacity 32K)
      • IIC bus interface, the maximum transmission speed  of 400KHz (working voltage of 5V)
      • Can be cascaded with other IIC device, 24C32  addresses can be shorted A0/A1/A2 modify default address is 0x57
      • With rechargeable battery LIR2032, to ensure the  system after power failure, the clock move any natural normal
      • Wiring instructions (with Arduino uno r3 for  example):
      • SCL → A5
      • SDA → A4
      • VCC → 5V
      • GND → GND
