Tiny AT24C32 I2C Module Precision Real Time Clock Module for Arduino
Tiny AT24C32 I2C Module Precision Real Time Clock Module for Arduino
Save time and high precision addition, also has some other functions that extend the system many additional functions and a number of options. The device integrates a very precise digital temperature sensor, through the I2C interface to access it (as at the same time). This temperature sensor accuracy is ±3°C. On-chip power supply control can automatically detect and manage the main and standby power (i.e. low voltage battery) to switch between the power supply. When the main power failure, the device can still provide accurate time keeping and temperature, the performance is not affected. When the main current repower or voltage value returns within the allowable range, the on- chip reset function can be used to restart the system microprocessor. Module parameters: 1. Size: 38mm (length) x 22mm (width) x 14mm (height) 2. Weight: 8g 3. Working Voltage: 3.3-5.5V 4. Clock chip: high-precision clock chip. 5. Clock Accuracy: 0-40℃ Measuring range, the accuracy is 2 ppm, the error is approx. 1 minute. 6. Calendar alarm clock with two 7. Programmable square wave output 8. Real-time clock generator seconds, minutes, hours, day, date, month and year time keeping and provisioning up to year 2100 leap year compensation 9. Chip temperature sensor with an accuracy of ±3°C. 10. Memory chips: AT24C32 (storage capacity 32K) 11. IC bus interface, maximum transmission speed of 400KHz (working voltage of 5V). 12. Can be cascaded with other IIC devices, 24C32 addresses can be shortened to A0/A1/A2. Package includes: 1 x Clock Module
