multifunctional clock

Overview

The main functions are as follows: 1. The power supply part uses a charge and discharge management chip based on TP5400 and is powered by a 3.7V lithium battery; 2. The timing part uses a clock chip based on DS1302; 3. The timing range is year, month, day, week, hour, minute and second; 4. Timing The time is displayed on LCD; 5. The button part is designed with four buttons, namely pause, position selection, change, and function selection; 6. The temperature detection is based on the AHT20 temperature and humidity sensor; 7. The temperature detection range is -40℃-85℃. The humidity detection range is 0-100%; 8. The storage function is based on the AT24C02 chip; 9. The liquid crystal display function is based on the LCD1602 module.
