Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad(); 1. Limited secondary filtering /* A value can be adjust...[Details]

Floating-point digital signal processing has become a constant requirement for precision technology, often in applications requiring high accuracy in areas such as aviation, industrial machinery, a...[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]

As LEDs continue to improve in almost every aspect of performance and cost, LED lighting is being used in an increasingly wide range of applications, among which LED street lights are a focus of in...[Details]

1 Introduction Solar street lights are mainly composed of four parts: solar photovoltaic cell components, batteries, charge and discharge controllers, and lighting fixtures. The bo...[Details]

Introduction Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]

Battery life is critical for portable applications. For applications such as smoke detectors, security devices, and thermostats, factory-installed batteries need to last for more than 10 years. The...[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]

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]

Overview In spectral measurement, photomultiplier tubes (PMT) and charge-coupled devices (CCD) are often used as photoelectric converters. PMT is used in slow-changing, high-precision spectral...[Details]

1. Disadvantages of choosing too high a voltage level Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]

D5026A is a driver IC designed by Shanghai Debei Electronics for energy-saving LED display screens. Its design concept is energy-saving and compatible with existing solutions, that is, it can be ...[Details]

0 Introduction Ultrasonic waves are mechanical waves with a frequency of more than 20KHz, and the propagation speed in the air is about 340 m/s (at 20°C). Ultrasonic waves can be gene...[Details]

Every time I go home and walk up the stairs, I am always scared. The corridor lights are often broken, and no one changes the bulbs, or they are not smart enough and need to be operated manually. E...[Details]
