How the microprocessor uses data from the sensors to control the washing machine?

How the microprocessor uses data from the sensors to control the washing machine?

Sensors. The primary triggers, or input devices, that tell the microprocessor in the washing machine that it is time to act in a certain way are sensors that detect conditions such as water level and temperature. Sensors also detect movement of the machine’s drum and other associated actions.

How are sensors used in washing machines?

Specific sensors can measure temperature, pressure, vibration, proximity and force. While a pressure sensor can monitor water level, a force sensor measures the payload weight at the beginning of the wash cycle. A proximity sensor verifies that the door is closed and latched before start-up.

How does a washing machine temperature sensor work?

A thermistor is essentially a resistor that changes its electrical resistance at varying temperatures. They are used in washing machines Because their electrical resistance at various temperatures is known, it’s easy for the washing machine to monitor a thermistor and detect when certain temperatures are reached.

How does a washing machine control system work?

The washing machine includes a controller communicating with the motor. The controller sends signals to the motor to rotate the basket at selective rotational speeds, and receives electronic signals indicating the power used to rotate the basket at selective speeds.

How the sensors and a microprocessor are used to monitor a process?

Sensors are used to measure physical quantities such as temperature, light, pressure, sound, and humidity. They send signals to the processor . For example: a security alarm system may have an infrared sensor which sends a signal when the beam is broken.

How does a microprocessor control?

A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer’s central processing unit.

What is the sensor in a washing machine?

Magnet sensors or Reed Sensors are used under the top loading door, with a magnet on the door, to stop the washing cycle instantly when the door is inadvertently opened in-cycle. This helps stop the motor and voids causing an accident.

Which temperature sensor is used in washing machine?

Modern machines use thermistors as Temperature Sensors. Thermistors are low-cost temperature-sensitive resistors and are constructed of solid semiconductor materials which exhibit a positive or negative temperature coefficient.

How do you control a washing machine?


  1. Inside the cycle switch.
  2. Inside the cycle switch.
  3. Speed and temperature control switches.
  4. Inside the speed/temperature control.
  5. Water level control switch.
  6. Water level control switch plumbing.
  7. Inside the water level control switch.

What does a control system do?

A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling processes or machines.

How are sensors used?

A sensor is a device that measures physical input from its environment and converts it into data that can be interpreted by either a human or a machine. People use sensors to measure temperature, gauge distance, detect smoke, regulate pressure and a myriad of other uses.

Why the data from the sensor has to be changed before it is read by the microprocessor?

Explanation: It has to be changed, as the temperature being recorded is analogue data, but the microprocessor can only read digital data. Hence, the data has to be changed from analogue data to digital data!

How does the microprocessor in a washing machine work?

It is the central processing unit that sends signals to the rest of the machine so that it operates correctly. The washing machine’s microprocessor tells the washing machine what to do, based on the selections you make for your laundry, such as the wash cycle and water temperature.

How are microprocessors used in a sensor system?

The roll of microprocessors in such a system is that the circuits on the microprocessor manipulate data in a pattern that can be programmed by software to make the sensor pick up their speciality. e.g movement. Q. There are many microprocessor controlled devices in the modern home. Describe the effects of these devices on peoples lifestyle’s.

What are microprocessor controlled devices in the home?

Microprocessor-Controlled Devices in the Home. Microprocessors are tiny little computer chips that are used in electronic devices in order to control something. There are lots and lots of modern devices that we use everyday that are controlled by a microprocessor.

What kind of sensors are in a washing machine?

The low-end MCU handles temperature sensors for both the water and motor safety and the Hall effect sensor input for rotor position as well as water line, final temperature and lid sensors. In contrast, the high-end MCU deals with these same sensors and adds a weight sensor.
