What is the role of microcontroller in a sensor based application?
A microcontroller consists of hardware and software components. The sensing data is sent to the microcontroller for processing, and it generates signals for actuators. In this way, the whole system could be controlled to the target state; (4) actuators: these are used to manipulate the environment.
What is AVR in UPS?
Automatic Voltage Regulation (AVR) in line interactive UPS systems stabilizes the incoming AC signal to maintain output power at a nominal 120 volts by controlling high and low voltages without resorting to battery power.
What are the advantages of microcontroller?
Advantages of the microcontroller: The low time required for performing the operation. It is easy to use, troubleshooting and system maintenance is simple. At the same time, many tasks can be performed so the human effect can be saved. The processor chip is very small and flexibility occurs.
How do you interface a sensor with microcontroller?
The sensor provides fully calibrated digital outputs for the two measurements. The digital signal is fairly easy to read using any microcontroller. Only one pin of the sensor, the pin 2 (Data pin) is connected to the microcontroller, pin 1 connected to Vcc of 3 to 5.5V and pin 4 to ground. Pin 3 is not used.
Is AVR needed?
If you live in an area with unreliable electricity, it would probably be a good idea to have an AVR or UPS. If you live in, say, the United States or Europe, an AVR is not necessary (though a UPS is still good to have; blackouts can occasionally happen anywhere).
What is AVR in marketing?
Ad Value Ratio (AVR) puts advertising performance on the right platform. A ratio of 1 or higher indicates success.
What is a microcontroller for?
The use of a microcontroller to implement the functionality of each subsystem and how to use it in many possible appli- cations is then given. This explains the main reason behind calling our book “Digital System Design” and not “Embedded System Design”; the use of the microcontroller as the processor in the system.
What is the difference between ARM microcontroller and AVR microcontroller?
ARM microcontrollers are manufactured by different companies like NXP Semiconductors, STMicroelectronics, Microchip Inc., Atmel etc. AVR microcontrollers are common among hobbyists and students. AVR microcontrollers are developed by Atmel, later acquired by Microchip.
What is Digital Input Output (I/O) in AVR?
Digital input output (I/O) is the basic feature supported by AVR micro controller. To facilitate digital input output, three registers are associated with each port of the micro controller. Data Direction Register– This register determines which of the pins will act as an output port, and which of them as input.
How to configure data direction register in AVR Studio?
In Avr Studio, go to ‘ Project Menu> Configuration Options> General ’. Here you can choose your device model and its operating frequency. As I’ve previously discussed, The Data direction register must be set up before doing any input/output operation. The LEDs connected to Port B blinks with 3 second time period.
