Click the above “Mechanical and Electronic Engineering Technology” to follow us A bus, known in English as “BUS”, is very much like a public bus. For instance, the route of a public bus is fixed, and anyone can take the bus to any stop along that route. If we compare people to electronic signals, this … Read more
Nowadays, infrared sensor technology has become very mature, integrating into people’s daily lives and playing a significant role. Before understanding infrared sensors, we should first understand what infrared rays, or infrared light, are. We know that light is a form of electromagnetic radiation, and based on human experience, the visible light spectrum ranges from 400nm … Read more
Smart sensors are sensors with information processing capabilities. They are equipped with microprocessors, enabling them to collect, process, and exchange information. This integration of sensors and microprocessors results in enhanced functionality compared to general sensors. Smart sensors have the following three advantages: high-precision information collection through software technology at a low cost; a certain level … Read more
The pyroelectric infrared sensor is a sensor with significant application potential. It can detect infrared radiation emitted by humans or certain animals and convert it into an electrical signal output. It is a new type of highly sensitive infrared detection component that can detect changes in the infrared energy radiated by the human body in … Read more
1. Bandwidth Generally refers to the range of signals where the sensor output response decreases to the square root of one-half of its maximum response or half of the power. Simply put, it indicates the range that the sensor can sample, and the bandwidth is the indicator of the sensor’s response range to external signals, … Read more
1. Working Principle Sensors are generally composed of four parts: sensitive elements, conversion elements, conversion circuits, and auxiliary power supplies. 1. The sensitive element directly senses the measured quantity and outputs a physical signal that has a definite relationship with the measured quantity; 2. The conversion element converts the physical signal output by the sensitive … Read more

In digital signal processing (DSP) systems, noise issues often arise. To ensure signal quality and improve system performance, many engineers opt for hardware noise reduction techniques. So, do you know how this hardware noise reduction is implemented? 1. Board Structure Domain Line Layout Optimization Use a large area ground plane with the power supply: ensure … Read more
In high-speed digital signal processing (DSP) systems, electromagnetic interference (EMI) is a critical issue that cannot be overlooked. Due to the high-frequency signal processing and complex circuit layouts involved in DSP systems, the electromagnetic environment becomes more complicated, easily leading to signal distortion, system instability, and even functional failure. Therefore, engineers need to understand the … Read more
