The Bluetooth technology is wireless technology and the main purpose of Bluetooth is used for the exchanging of data in between the two electronic devices. There is a short distance between the two electronic devices and it is built by using the personal area network. This technology is developed by the Bluetooth special interest group and its physical range is from 10m to 100m. The Bluetooth device can connect up to seven devices and it is used in the industry like smartphones, personal computers, and gaming consoles, etc. The IEEE standardized Bluetooth as IEEE 802.15.1, but the standards are maintained for short periods.
The microprocessor is the main important or the heart of the normal computer. Generally, we will use the microprocessors like Pentium, AMD, power PC, or any other brands and types of microprocessors. The microprocessor is also called as a central processing unit. The microprocessor is totally computation engine and it is fabricated on the single chip. The Intel has released the first microprocessor in the year 1971 and it contains the 4-bit microprocessor and having 2300 transistors, 640 bytes of memory addressing modes and with a clock speed of 108 kHz.
Capacitors are used commonly and useful as an electronic component in the modern circuits and devices. The capacitor has a long history and usage with more than 250 years ago the capacitors are the oldest electronic component being studied, designed, developed and used. With further technology, the capacitors are come up with different types based on their factors. In this article, we are discussing the most popular and most useful types of capacitors. The capacitor is a component and it has the ability to store energy in the form of electrical charge produces the electrical difference across its plates and it is like a small rechargeable battery.
To control the speed of a motor, there are different ways. But in this tutorial, we are explaining simple and easy way by using the pulse width modulation (PWM). The modulation is a process of varying the parameter of a carrier signal in accordance with the instantaneous value of the message signal. The modulation process is used to reduce the size of the antenna and increases its efficiency. PWM is a technique used to generate the analog signals from the digital devices like MCU. All the modern MCU’s have dedicated hardware for PWM signal generator.
In the industrial automation, the Temperature Sensor is used to measure the temperature. The temperature sensor uses the converter to convert the temperature value to an electrical value. To read the temperature correctly & control the temperature in the industrial applications the temperature sensor is used more widely. In between the different types of sensors, we can make large peculiarities and the sensors will have the different properties like temperature range, contact-way, sensing element, and calibrating methods. The temperature sensor consists of a sensing element together in housings of plastics or metal. By using the conduction circuit the sensors will reflect the charge of environmental temperature.
