A: solar street lamp controller recovery voltage

We often encounter a customer response, my lamp is normal light a few days before, a few days after the rain, can not work properly, check the normal solar controller indicator, the battery also has 12V voltage, lamp source also bright which directly connected to the battery, what is the problem, replace a controller,then good. Here to understand the solar charging controller has a recovery voltage, the general controller recovery voltage point is 12.5V, only when the battery voltage exceeds the voltage point, the solar street lights can automatically reply

UHF RFID can simultaneously read both near-field and far-field RFID labels. Due to the diversity applications, an UHF RFID reader can more efficiently satisfy read requirements in many operating environments. For example, in large parking lots, such as small and medium-sized trucks, trucks, staff and visitor vehicles, etc., their security access control systems must consider the requirements and restrictions of all vehicles. UHF RFID has the advantages of far-field reading, to meet the needs of different high and low reading position, for example, patrol large range applications (such as university campuses or large hospitals), the long range UHF RFID reader mounted on the patrol car, patrol officers sitting in the car and directly read and verify the electronic tag data.

RFID room automatic guidance system contains remote RFID reader at where it need to place the guide, when the person passing through the card is automatically identified at long-distance (the card can be put anywhere on the player). And system shows the cardholder the location of the room and the electronic map animation guide. The system can also be extended, such as access control, VIP, multimedia player and other functions.

The application of RFID technology in production management helps manufacturers to monitor the operation of production line equipment components and manage the products in and out of warehouses, and manage the warehousing of distribution centers.

According to our customers' feedback from years, the first time using RFID reader device, they often encounter some common problems.

In the early morning of November 10, the official ball of the 2018 World Cup in Russia was created with brand new technology. Called the "Telstar 18" (TV star), the football is printed on a gold-colored Russian World Cup Logo with a gradient mosaic pattern and a built-in NFC chip. Using many new technologies and innovative NFC chips, you can transfer data with your smart phone. Each ball generates a unique identifier that allows the user to unlock exclusive data messages. So what is NFC and what is the difference between RFID and RF technology?

With the development of society and the constant construction of cities, various office buildings, commercial buildings and residential buildings have mushroomed and become the rulers of social development.
