The generally used RFID module is RC522 which falls under High frequency Passive RFID system. It is mostly used with microcontrollers likeArduino,PIC,AVRand other microcontrollers that support communication protocols like SPI, IIC or USART. Its interface is simple and has readily built libraries for...

NB-IoT stands for Narrow Band Internet of Things and it is a low-power wide-area (LPWA) technology that works anywhere. NB-IoT allows devices to perform wireless transmission over long distances at a much lower cost while consuming very low power for extended battery life. More importa...
A semiconductor is mainly an insulator. But, the gap of energy is lesser when we contrasted to insulators. The valence band is somewhat thermally occupied at the temperature of the room, while the conduction band is somewhat unoccupied. Becauseelectrical transmissionis openly linked to the number...
Internet of Things-IOT based energy meter reading through the internet is an innovative application of real time embedded systems. Using this project you can avail the facility of displaying (in the format of chart and gauge) units of power consumed and the cost of consumption over the internet...
The resistance can depend on theOhm’s lawwhich is discovered by the German physicist namely “Georg Simon Ohm”. Ohms Law TheOhm’s lawcan be defined as; the voltage across a resistor is directly proportional to the current flow through it. The Ohms law equation is; ...
In practical, this method cannot be used as it requires an extremely large anode voltage to the cathode. Once the voltage is high than the break over-voltage, then it offers extremely huge currents. This may cause harm to the thyristor. So, in most of the situations, this kind of SCR ...
A BAN (body area network) or a WBAN (wireless body area network) is a wireless n/w of the wearable computing device. These devices may be placed in the human body or surface mounted on the human body in a particular position. The growth of attention in wearable technologies such as glas...
In digital signal processing, an FIR is a filter whose impulse response is of finite period, as a result of it settles to zero in finite time. This is often in distinction to IIR filters, which can have internal feedback and will still respond indefinitely. The impulse response of an Nth...
From the equation above, ‘I’ is load current, ‘f’ is i/p frequency of AC and ‘Vpp’ is the minimum ripple that may be acceptable because almost it’s never possible to make this ‘0’ Filter Capacitor Circuit The circuit diagram of the filter capacitor is shown below. In this ci...
