Design of temperature acquisition and alarm system based on STM32 (source program, schematic PCB, etc.)

When the temperature is lower than the set threshold, the corresponding indicator light lights up and the corresponding relay is closed. The relay can drive the load (fan, refrigeration plate, heating tube, etc.). When the temperature is higher than the alarm value, the sound and light alarm will sound. The keys are setting keys, plus key and minus key. The alarm value and temperature control range can be set, the temperature measurement range is 0 to 99.9 degrees Celsius, and the accuracy is 0.1 degrees Celsius.

Schematic PCB

AC current measurement system based on STM32 (program, circuit information)

The overall structure of this design is roughly composed of a main control module, a current signal sampling module, a power module and a serial port output module. In this article, the main control chip uses a microcontroller model STM32F103RC, which makes the structure as small as possible while ensuring the current sampling accuracy. It is as simple as possible, avoids complex and changeable circuit layout, is more convenient for PCB board production, and is relatively low-cost. Among them, in the design of the sampling conditioning circuit, a current transformer is used to sample the current signal.
