8. An Arduino based bath chair as claimed in claim 1 wherein: the handheld terminal is a mobile phone, and an APP capable of mutually accessing the communication module is additionally arranged in the mobile phone; the model of the Arduino controller is Arduino-Uno; the communication module is NodeMcu; the model of the temperature sensor is MCU-680; the infrared sensor is TCRT 5000; the model of the functional switch is KCD 1-101; the Bluetooth download module is HC-42nRF 52832; the signal indicating lamp is AD16-22 SM.
9. A control method for bathing by using the Arduino-based bath chair as claimed in any one of claims 1 to 8, comprising the steps of:
1) the signal acquisition mechanism sends a sensor signal, the function switch sends a function switch signal: the infrared sensor identifies the posture of a human body, the temperature sensor measures the average value of water temperature, the function switch reads whether the function subswitches corresponding to different functions are pressed down or not, and the read data are transmitted to the Arduino controller through a DuPont wire;
2) arduino controller reads data: the Arduino controller processes the read data and sends the data to the current state of the bath chair of the mobile phone APP through the communication module, when a user wants to take a bath, corresponding buttons on an interface of the mobile phone APP are pressed or the control of the mobile phone APP is selected, corresponding instruction data are sent to the Arduino controller through the communication module, and otherwise, the mobile phone APP does not return any data and only receives the data;
3) the Arduino controller judges whether to self-process: after the Arduino controller processes and transmits data of each sensor, if the data are processed, instruction data from a mobile phone APP are received, a mobile phone APP processing mode is entered, the mobile phone APP is used as a control core at the moment, if different bathing device buttons are pressed, corresponding bathing devices are immediately controlled, and an electric push rod, a shoulder massage motor and a leg mechanical arm bathing device operate according to instructions; if the temperature measured by the temperature sensor is not equal to the preset value, bathing is suspended, and bathing under the condition of overhigh temperature or overlow temperature is avoided; when bathing, the Arduino controller controls the bathing devices in the corresponding areas to work, so that the massage corresponding signal indicator lamps are turned on when the shoulder massage motors controlled by the Arduino controller operate to bath the shoulders, and meanwhile, the Arduino controller controls the corresponding leg mechanical arm bathing devices to turn on the leg bathing corresponding signal indicator lamps; the user can also directly turn on or turn off a certain bathing device through the function switch;
4) after bathing is finished, the Arduino controller controls the electric push rod to rise, a corresponding signal indicator lamp is turned on when a person is lifted, the infrared sensor senses and identifies that a human body leaves an area, the electric push rod slowly and controllably descends to a flat plate state, and bathing is finished.
