Efficient Energy Management System with Smart Grid

Efficient Energy Management System with Smart Grid: Efficient Energy Management System  was inspired by Supervisory control and data acquisition (SCADA). Efficient Energy Management System with Smart Grid  basically controls, monitors loads and power flow. It also provides protection to loads.We usually have some critical and non-critical loads. Critical loads should never be turned off. Non-critical loads ...

Three phase ac power measurement using pic microcontroller

Three phase ac power measurement: three phase watt meter using pic microcontroller is designed to measure three phase ac power of three phase transformer and three phase generator. It can be used to measure either three phase ac power of transformer or three phase generator. As you know AC power or wattage of any three phase ac equipment is difficult to measure with the help of microcontroller due to non li ...

Surrounding Gate Transistors – Price + Size + Performance

Intel co-founder Gordon Moore predicted in 1965 that the number of transistors per silicon chip would double every two years. This came to be known as Moore´s Law which has been proven accurate for the last fifty years. Many scientists argue that the law is soon to be broken because of physical limitations. The end of Moore´s law would mean a stagnation in computer processing and power and could cause econo ...

MMC/SD Card raw data read with PIC16F887 microcontroller

Interfacing MMC/SD card with PIC16F887 This small example shows how to read SD card raw data (bytes, sectors ...). SD card raw data means that there is no use of system files like FAT16 or FAT32. Serial monitor is used to display the data after reading it and here the UART protocol is used. the link below shows a small PIC16F887 MCU UART example: UART Example for PIC16F887 microcontroller using CCS PIC C co ...

Read text files from FAT16 SD card with PIC16F887

Interfacing PIC16F887 with FAT16 SD card After reading raw data (bytes and sectors) from SD card, now I'm going to use FAT16 file system to read and print text file located in 2 GB SD card. Read SD card raw data topic: MMC/SD Card raw data read with PIC16F887 microcontroller UART protocol is used to display the content of the text file. For this project, I used MMC/SD card driver for CCS C compiler which ca ...

Interfacing PIC16F84A with SD card

This topic shows a simple interfacing of 2 GB micro SD card with PIC16F84A microcontroller. I used the PIC16F84A to read the SD card raw data which doesn't require a microcontroller with high RAM or ROM. In this interfacing I used software SPI because the PIC16F84A doesn't have a built-in hardware SPI module. In this example there is no need for file systems (FAT16, FAT32 ...) because we're dealing with raw ...

CH340E, A NEW SMALL SERIAL TO USB CHIP

WCH, a Chinese integrated circuits manufacturer, has just released a new serial to USB chip called CH340E. Unlike other CH340 chips, it doesn’t require an external crystal and also needs less PCB space and BOM. CH340 is a 3x3mm tiny chip comes in MSOP10 package and has 10 pins. Although it is smaller than other alternatives, it is a little more expensive than them. But considering other components and PCB s ...
