RFID Sensor Module WS1850S 13.56MHz High Frequency Identification Sensor

The RFID2 module features a built-in WS1850S chip operating at 13.56 MHz to enable non-contact reading and writing of RF cards through magnetic field induction. It supports multiple card authentication and encoding functions for straightforward integration into electronic verification projects. 1. Constructed from plastic with two standard LEGO compatible mounting holes, the component provides a reading and writing distance of less than 20 mm and functions reliably across operating temperatures from -20℃ to 85℃. 2. The integrated I2C interface delivers a fast mode data rate of up to 400 Kbit/s and a high speed mode rate of up to 3400 Kbit/s, utilizing a 64-byte transceiver buffer while retaining stored data for more than ten years. 3. Compatible with Arduino and UIFlow development platforms using Blockly or Python, the sensor supports ISO14443A, MIFARE, and NTAG card protocols for direct tag recognition and authorization. 4. Suitable for everyday identification workflows, the module applies directly to access control terminals, employee attendance stations, warehouse storage tracking, vehicle entry registration, and smart library shelving systems. 5. The package includes exactly one RFID Sensor Module, with physical design details and printed labels subject to normal manufacturing batch variations that do not impact operational capability.
