Curriculum Design/Graduation Project/51 Microcontroller/Thermometer/Portable Digital Thermometer

Microcontroller chip STC8A8K64S4A12. Package LQFP-64_10x10x05P
Touch switch C318884 and cooperate with MOS tube C85758 to realize power control.
Use a three-digit SMD digital tube to display the temperature with an accuracy of plus or minus 1 degree.
The digital tube is directly driven by the IO port, without an additional driver IC.
Use C70373 to solder a battery holder and insert a CR2032 coin cell battery.
Chip temperature sensor, C177147 , voltage 1.7V to 5.5V.
Design a layer of PCB cover with copper pillars or pin headers installed in the middle to protect the lithium battery and sensor and expose the typical stress-bearing locations for push buttons.
The location of the button battery should be easy to replace.
