The rapid development of smart technology has made our daily life more convenient and comfortable. As one of the smart home products, the smart toilet receives and processes the data from the sensor through the single-chip microcomputer, and then controls the various functions of the smart toilet through the control module to achieve comprehensive control and adjustment of the smart toilet. This article will introduce the detailed application of CW32 microcontroller in smart toilets.

Introduction to the application of CW32 microcontroller in smart toilet
1.Temperature sensing and control
The smart toilet is equipped with a temperature sensor, which can sense the seat temperature required by the user in real time and adjust it according to the user's settings through the processing of the CW32 microcontroller. When the temperature is too high or too low, the microcontroller will send a signal to adjust the heating or cooling of the seat through the control module, providing a more comfortable experience.

2.Intelligent flushing function control
CW32 microcontroller receives the user's operation instructions, carries out flow detection, and accurately controls the work and stop of the water pump according to the user's required water flow size and flushing time.
3.Intelligent power monitoring and energy-saving function
The smart toilet has a built-in battery or power module, and the CW32 microcontroller can monitor the power of the battery in real time and intelligently adjust it according to the power situation. When the power is insufficient, the microcontroller adjusts the power supply through the control module to extend the service life of the battery. For example, by reducing the heating power or reducing the flushing time, the efficient use and saving of electrical energy can be achieved through intelligent power management.
This smart toilet uses Wuhan Xinyuan Semiconductor's 32-bit low-power CW32L083 series, which integrates an Arm Cortex-M0+ core with a frequency of up to 64MHz, up to 256KB Flash, up to 24KBram, up to 87 GPIOs, and a series of enhanced peripherals.
