Design of temperature control faucet based on STM32

With the development of the times, people are increasingly pursuing the comfort and convenience of life. Water is an indispensable part of people's family life. At this stage, the faucets used in most families adjust the water temperature through manual and mechanical rotation. On the one hand, the adjustment speed is slow. On the other hand, it is often difficult to accurately achieve people's really comfortable water temperature. The water outlet is either hot or cold(Tan 2013). The temperature control faucet designed in this paper is different from traditional products. It takes the STM32 single chip microcomputer as the control core, uses the high-precision temperature sensor DS18B20 to detect the ambient temperature, sends the digital temperature signal output by the AD conversion module to STM32 for processing. It displays the current ambient temperature value and each gear temperature value preset with the key on the LCD display screen. In addition, using the existing voice signal module, we can convert the voice signal into the input signal of single chip microcomputer, and then use PWM to change the speed of stepping motor, so as to control the water flow and temperature more conveniently and quickly.
