electrostatic wristband

Electrostatic inductionPerimeter detectors are very sensitive sensors. To ensure proper use of the system and give full play to its functions, the project installer must carefully read the product instructions before construction, check the cables, ground wires, power cables, and installation according to the product instructions carefully before determining the fault. Then, the test starts after 5 minutes of power-on:

People in the carpet or sofa stand up, the human body voltage can be as high as 10,000 volts, and the rubber and plastic film industry electrostatic can be as high as more than 100,000 volts. So, why is the voltage of static electricity so high? The following author from the electrostatic generation principle began to analyze. A The principle of electrostatic gen

! By the way, there's a little trick to forget to tell you, perhaps a lot of friends are using the Display protection screen, this device can prevent radiation and electrostatic damage, display protection screen has a leader to export the received static electricity, you can connect the other end of the lead wire just produced in any part of the electrostatic conduction line, Simply cut a small opening of t

Electrostatic sensor perimeter detector debugging: 1. After all devices are installed and connected, power-on is enabled for debugging. 2. debugging is performed according to the operation interface on the detector panel. The details are as follows: 3. Power supply light: After the detector is powered on for V, the power supply light will light up. When the AC power is out of the 187V-242V range, the power supply light will flash. 4. Cable light: when

A while ago a friend said they had a project in which there was a process circuit for ESD protection. I couldn't understand it at the time. But then the more I see the more I understand. Now share with you. is also a contribution to high-tech. The right of the regulator diode plays the role of the control voltage, when the regulator diode conduction, will be in its high over a current, the current through the resistance below, will cause the voltage on both sides of the lower resistance rise, th

In the first year as an electronic engineering student, you've been told repeatedly that electrostatic discharge (ESD) is a phenomenon of electrical transients and poses a serious threat to electronic circuitry. The most common reason for electrostatic generation is that the friction between the two different materials causes the charge to accumulate on the friction surface. The use of handheld and wearable

Electronic products in the CE certification, often need over-radiation interference ( 1. If the low-frequency exceeded, the general is the input power radiation out, to ensure that the use of DC adapter qualified, and then the PCBA board power input processing, usually wire string beads, capacitance to ground and other processing. 2. If it is high-frequency exceeded, the general is a clock (system clock, crystal clock, peripheral chip clock foot) of the multiplier radiation, first determine wh

Failure phenomenon: The small new air series is made of metal shells. When charging, the fuselage has inductance and hemp hand situation very possibly is the metal machine Shell surface Area Bureau's electrostatic charge. Solution: We have been strictly tested, metal fuselage surface electrostatic is less than 0.05mA, far less than the safety regulation of 0.25mA, please feel free to use.

In fact, I do not know what should be called the effect of better, it is called electrostatic effect bar. Effect Chart: 1. Create circular text: 2, the use of circular text lightning and zoom blur effect: 　 　 3, to flatten the layer, apply the gradient effect: 　 　 　 4. Clone bitmap: Note: The zoom blur mentioned in the tutorial is MX2004 version, which involves the Xenofex filter, has been provided many times in the Dream forum downl

StormFly: LikeaPCOnYourWristStormFly is loaded with the operating system and corresponding software, and allows you to wear it on your wrist like a watch for easy carrying. In essence, StormFly is a USB device installed with the Ubuntu Operating

For users of Xiaomi bracelet 2, let's take a detailed analysis and share with you how to set up the number of steps to reach the standard.Tutorial sharing:1. Open the Xiaomi Sports APP, click [smart play], and then select [more]  2. Click "standard

with my friends is more beautiful. My view of things is more comprehensive, and even improves the suffering of my insomnia. When I open a book, I think tomorrow morning I will also take part in "21 days without complaints"-with a purple bracelet. I think I have a good temper and often think about it. I would like to finish this task well. I didn't expect my first day of the morning I was just blinking and complaining: Ah, 10 minutes later, I have to be late and deduct money again. Damn it! And

Computer motherboard static electricity how to do To prevent static electricity, first of all to understand what is static electricity, how electrostatic is produced. Static electricity (static electricity) is an electric charge in a stationary state. and the creation of static electricity, any matter is composed of atoms, the basic structure of atoms are protons, neutrons and electrons. The scientists defined the proton as positively charged, the ne

We will give you a detailed explanation of the steps for upgrading the firmware.Tutorial sharing:1. Open the matching Xiaomi Sports APP, click my at the bottom, and then click the bound wristband device.2. After entering this interface, Xiaomi sports will automatically detect the firmware version number of the wristband. If there is a version that can be updated, a prompt will pop up after a few seconds. Cl
