and the 1-wire adapter can form a simple read/write device at a cost between $38 and $43. The onewireviewer demo software and SDK can be downloaded free of charge from the website. What are the advantages of iButton over other technologies? When developing an iButton solution, you may think of many complementary technologies. It may be a bar code, RFID tag, magnetic stripe, sensor card, and smart card. Unlike bar codes and magnetic stripe cards, most

The entire book borrowing process did not involve staff or even take the initiative to swipe the card. This is a cross section of university life that demonstrates the integration of modern information technology, modern IoT technology, and virtual reality technology. Now, the "smart campus" has been officially approved by the First National educational informatization pilot Unit of the M

In the BS structure of the program, how to develop a cross-web browser IC card reader program?In general, the use of physical hardware in a BS structure program has many limitations, and the OCX control that is addressed through ActiveX technology is only available on IE and cannot be used in Chrome or Firefox. Friends of my technology to provide RFID reader cloud services to completely solve this problem, he can not only use in IE, but also in the Ch

the wrong information, the reason may be the problem of the code, because the use of wireless transmission to use the protocol stack, and this ZigBee does not run the protocol stack, so wireless transmission will definitely have problems. Using the wireless serial number transmission module CC1101 to debug the discovery or there is a problem, the reason may be the timing problem, if you want to completely solve this problem, there is still a lot of difficulties, the topic is only wired data tra

) devices between the connection. Bluetooth does not have this limitation and is not blocked by walls. The current research direction of IrDA is how to solve the problem of line-of-sight transmission and improve the data transmission rate. NFC Technology NFC is a short-range wireless communication technology standard that is driven by Philips, Nokia and Sony and is similar to RFID (non-contact Radio frequency identification). Unlike

A key challenge for software to define network potential users is to judge the specific value of a particular SDN controller, which, after all, plays a key role as a bridge between network applications and network infrastructures. However, there is no model to standardize SDN, and there is no standard that a SDN controller must comply with. Although the advent of the Linux Foundation's Multi-vendor Opendaylight Project offers hope for the SDN stack required for a unified modular controller arch
