The PCB of the industrial "safety" control system based on Hercules is progressing step by step, and I hope the single board will pass! 99SE's 3D effect...
We know that due to the large voltage gain of the op amp, the open-loop voltage gain of a general-purpose operational amplifier is generally above 80 dB. However, the output voltage of the op amp is l...
I am making a device that uses msp430f2618 to control the illuminance sensor BH1750FVI to measure light. Since I am not familiar with the msp430 I2C module, I guess the program is wrong, and the resul...

For a long time, due to the limitation of hardware conditions, the display devices of traditional small handheld devices such as PDA are usually monochrome LCD, and the user interface is very simpl...[Details]
1 Introduction
Ultrasonic waves have strong directivity, slow energy consumption, and can propagate over long distances in a medium, so they are used for distance measurement. Ultrasonic detec...[Details]
This article will introduce a design method for a distributed control system used in a tracking car, which can perform distributed control of motor modules, sensor modules, and lighting control mod...[Details]
1 Introduction
Ultrasound refers to elastic vibration with a frequency higher than the audible frequency limit (i.e., in the frequency band above 20 kHz). The propagation process of this vib...[Details]
Abstract: In order to realize wireless automatic alarm and monitoring of major safety places, based on the basic principle of pyroelectric infrared sensing, a detector for receiving infrared radia...[Details]
Leakage current is generated by parasitic resistance paths between the measurement circuit and a nearby voltage source. This current can significantly reduce the accuracy of low current measurement...[Details]
In industry, voltage 0…5 (10) V or current 0 (4)…20 mA is usually used as a method for analog signal transmission, which is also a method often used by programmable controllers. So what are the dif...[Details]
Energy conservation and environmental protection are the main directions of current automotive technology research, and power batteries are the key to electric vehicle technology. Research on powe...[Details]
