Temperature alarm

Overview

Features
include the ability to use modular DS18B20 and DS18B20 transistors
to support high-precision temperature detection (four decimal places).
The alarm device uses a buzzer, which is inexpensive and practical.
Important notes:

Pay attention to chip soldering and component orientation

. Passive
buzzers have
a lower volume, while active buzzers have a higher volume. The source
code is included in the compressed package.
The set temperature is 15 degrees Celsius
and can be changed in the main function of the source code.
If using a DS18B20
transistor instead of a DS18B20 module, a 10K pull-up resistor must be connected to the P37 port of the chip.

Problem downloading program from SEED-EXP430F5529 using IAR via eZ400-FET.
Hello everyone; 1/ After receiving the SEED-EXP430F5529 team, I set SW1 to LDO or eZ430 respectively, and powered it with USB. The program can run, and the screen display and program test are normal.
