In early 2002, I started to write a working program for an IC card prepaid electricity meter. The meter used Philips' 8-bit 51-expanded single-chip microcomputer 87LPC764 , and wa...[Details]

Microchip's PIC18F46J50 is a low-power, high-performance 8-bit USB microcontroller (MCU) using nanoWatt XLP technology. The current in deep sleep mode can be as low as 13nA, the operating voltage i...[Details]

All electronic design engineers and scientists have performed electrical signal analysis, or signal analysis for short. Through this basic measurement, they can gain insight into signal details and...[Details]

I. Introduction In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]

Two simple circuits are implemented to drive two LEDs from a battery powered microprocessor. This design is based on a circuit that uses three resistors and a microprocessor I/O pin as an input h...[Details]

0 Introduction With the development of society, people pay more and more attention to security work. Monitoring products have been used in various fields instead of being used only in importan...[Details]

1. Introduction At present, most lighting equipment still uses traditional energy for lighting. Making full use of solar energy as the energy supply for lighting equipment is of great si...[Details]

Microcalorimetry is used to determine energy relationships. Microcalorimetry techniques are often required when performing calorimetric experiments with small sample sizes or slow heating rat...[Details]

A standard cell is an electrochemical cell used as a voltage reference standard in many electrical standards laboratories . If properly maintained, standard cells are very stable. The ...[Details]

Overview: This paper introduces a method of connecting a CAN-bus network with Ethernet to form a medium-sized remote monitoring/data transmission network. CAN (Controller Area Network) is ...[Details]

Many battery-powered systems require a visual indicator to show when the battery needs to be replaced. LEDs are commonly used for this purpose, but they consume at least 10mA of current. This con...[Details]

Printed circuit boards ( PCBs ) are used in most electrical products . If a PCB has low insulation resistance (IR), the performance of the circuits on the PCB will be greatly reduced...[Details]

With concerns about the growing energy crisis, motor efficiency has become an important and timely topic. This is because motors use 63% to 70% of the electricity produced in the United States and ...[Details]

With the rapid development of cities and the improvement of citizens' living standards, the number of various vehicles in cities is growing, and the demand for parking spaces in major commercial an...[Details]

Among the uses of electrical energy, lighting accounts for a considerable proportion. Compared with the earlier ordinary incandescent lamps, the fluorescent lamps and energy-saving lamps we commonl...[Details]
