microcontrollers in PCs are the most visible, they account for just 6% of of the

If the probe to be treated has a great volume ( like drying foods in foodstuff industry or ceramic materials microwave drier ), this multimodal cavity is suitable for a treatment because many parts of the local power distribution are intersecting the probe volume. microcontroller functions while cooking a bag of popcorn in a microwave oven. In this A microwave oven controller takes input from a keypad, displays output on an LCD display and controls a relay that turns the microwave generator on and off. 1. 1. In the partial fulfillment of the course INSTR/EEE 241 – Microprocessor Programming & Interfacing BITS- Pilani K.K.Birla Goa Campus Project by: NAVYA (2011A3PS240G) VAMSI REDDY (2011A8PS346G) OMPRAKASH REDDY (2011A8PS317G) GAUTHAM REDDY (2011A8PS364G) 2. Another example is a microwave oven. A few minutes later, a tone Microwave ovens have been a fixture in domestic kitchens for several decades, thanks to their core-to-crust heating ability, low cost and ease of use.

here, Used in everything from the simplest lawn watering controller to

Some of those applications included microwave ovens, where the keypad, clock, and oven settings were monitored by a microcontroller, and gas pumps, where metering of the gasoline and the starting of the pump were handled by the embedded computer system.

Because the high anodic temperature ( 150 C ), a cooling system ( with cold water and air flow ) is required. The magnetic field of the magnetron is produced in two coils ( L1 supplied from a PWM based constant current source, with max.10A and 20V voltage swing and L2 supplied by a feedback anodic current ).

What happened behind the scenes? The microwaves reflect off the metal interior of the oven and cause the water molecules in food to vibrate.


This is a simple example of a microcontroller application. The firmware is a software translated into a hex code by a compiler [3] or an assembler and stored in microcontroller’s [1] memory by a programming sequence, assisted by the PC and by a hardware programmer [5] board. 3. The user must have a total control for the microwave radiation like: modifying continuously the output power in a large range ( not only the output energy used in almost all home-appliance ovens ) and controlling precisely the treatment period. All supplying algorithm are supervised by microcontroller board (4) with a simple interface user (6) consisting in four functional buttons ( the same buttons have different functions displayed on the second line of the LCD as the program flow chart required) and a large LCD display. We present here, briefly, our design concerning a 5KW magnetron oven with an effective volume of 1 cubic meter, based on continuous wave CK 101 magnetron and driven by a flash microcontroller PIC16F877.

Microcontrollers are used in applications requiring repetitive Microwave ovens heat food using microwaves, a form of electromagnetic radiation similar to radio waves. With wavelength between 30 cm and 3 mm and power between mW and 500 KW they are used practically in all fields from medicine to industry. area network (CAN), and security functions. Microcontrollers are used in applications requiring repetitive operations such as running the traffic light at an intersection. Powersupply and CRT deflection and microcontroller test circuit. Today’s microwave ovens do much more than just heat food. This popular kitchen appliance now handles sophisticated cooking such as baking, steaming, frying and fermenting.

Microcontrollers are available with extra features such as analog-to-digital serial port, input/output ports (I/O) and a clock oscillator. A microcontroller is often small and low cost. 2.The concept In fig.1 is shown the typical structure for our high power microwave oven: Fig.1 Typical high power structure of a microwave oven – A microcontroller is often, but not always, Information about the device's operating system, Information about other identifiers assigned to the device, The IP address from which the device accesses a client's website or mobile application, Information about the user's activity on that device, including web pages and mobile apps visited or used, Information about the geographic location of the device when it accesses a website or mobile application. There are several basic parts that make up a microwave oven, including the magnetron, turntable and electronic control panel. In this application, the microcontroller's sole function is to turn lights on and off at predetermined times. A device called a magnetron inside the oven produces microwaves. Microwaves have three characteristics that allow them to be used in cooking: they are reflected by metal; they pass through glass, paper, plastic, and similar materials; and they are absorbed by foods. operations such as running the traffic light at an intersection. Introduction. typically combining an arithmetic logic unit (ALU), memory, timer/counters,

The CPU loads the program from somewhere. All other parameters like door status ( open or closed ), cooling water pressure, treatment period and output microwave power are also under microcontroller control. The microwave power absorbed in the material, assuming that all microwave power is transformed in warmth, is (equation 2): Any microwave oven is a multimodal microwave cavity in which the incident power ( usual 700W to 70KW at 2.45 GHz ) has a particular distribution . 2.The concept With a vavelenght between 30 cm and 3 mm and a power between 1 mW and 500 KW are practically used in all fields from medicine to industry.
