So generally, the reader gives out a 125KHz frequency through its coils, and if a similar 125KHz passive RFID tag is within the frequency field, it gets energized. The working principle of EM18 is about using radio waves to identify a specific RFID tag.

Reading circumference of 10 centimeters depending on tag location.

Wide range of operating temperature of between 0✬ to +80✬.

The EM18 comes with a set of very unique and specific features and specifications. If Low, it uses WEIGANDĭata is communicated through TX via RS232 communication Pin No.Ĭonnects the positive side of the power source to the device The EM-18 bears a nine-pin configuration whereby seven of the pins are connected, and two aren’t. So, if an ID is within a particular range, the reader will sense it and transmit this information to the microcontroller or PC. The RFID reader has a fixed transceiver and antennae to receive the signals. It quickly scans and reads ID tags within a specific radiofrequency. The RFID comes with a tag and a reader, where the EM18 falls in. But with RFID, you do not need to watch whatever you want, as long as it is within the radio wavelength that the RFID is transmitting. For it to work, you need to optically scan the bar in front of a reader to take stock like they do in supermarkets.

To better understand, let’s take a bar code reader instance. To begin with, RFID (Radio-Frequency Identification) is a wireless technology that employs the use of radio waves to identify whether an RFID tag is present. For everyone in the tracking world an d electronics enthusiasts, this will be a complete guide to the EM18. So, this article will highlight more about the EM18 RFID reader.

The usage of RFID is not only limited to companies that have inventory but can also be usable in casino chips and other tracking tasks like pet tracking. RFID tags revolutionized the world of business where it made it simple to keep track of goods and manage data. An RFID is a piece of standard tracking equipment that we can use in our day-to-day life.
