Download：
1. After downloading the software, double-click to run the application, connect the M5 device to the computer through the data cable, select the port parameters, and click burn to start recording. (When recording M5StickC, set the baud rate to 750,000 or 115200)
2. Currently, EasyLoader is only applicable to Windows operating systems, compatible with M5 systems, and uses ESP32 as the control core host. You need to install the CP210X driver before burning M5Core (if you use M5StickC as the controller, you do not need to install it) [Click here to view the driver installation tutorial](/en/uiflow/uiflow_web# install the serial driver)

Reliable RFID Sensing for Smart Identification Systems
The Radio Frequency Identification Sensor WS1850S MHz is designed for applications that require fast, contactless identification and tracking. Operating in the designated MHz band (depending on the specific configuration), this sensor reads compatible RFID tags quickly and accurately, making it suitable for access control, asset management, inventory tracking, automated check-in systems, and industrial automation. It’s a practical core component for building modern smart systems that need efficient data capture without manual scanning.

Fast, Contactless Data Reading
Using radio frequency technology, the WS1850S sensor can detect and read RFID tags within its supported range without line-of-sight contact. Items or badges only need to pass within the sensor’s field to be identified, significantly speeding up workflows compared to barcodes or manual data entry. This makes it ideal for environments where many items move through gates, conveyor lines, or entrances, such as warehouses, offices, libraries, or production facilities.

Stable Performance with High Recognition Accuracy
Engineered for stable RF performance, the WS1850S offers strong anti-interference capability and reliable tag recognition, even in environments with multiple signals or metal racks. It is designed to minimise missed reads and duplicate reads, ensuring that tracking and logging remain accurate. Consistent performance helps maintain data integrity in systems where every scan is important—like stock counts, access logs, or process control.

Flexible Integration into Existing Systems
The sensor is built to integrate easily with controllers, microcontrollers, industrial PLCs, or embedded systems via standard electrical interfaces (depending on the model). This allows developers and system integrators to incorporate RFID functionality into gates, terminals, kiosks, handheld devices, or fixed readers. Whether used in a standalone unit or as part of a larger automation platform, the WS1850S serves as a solid RFID front-end.

Compact Design for Multiple Installation Scenarios
Thanks to its compact size, the WS1850S RFID sensor can be mounted into tight spaces such as enclosures, panels, machine housings, or small terminals. Its design suits both visible and hidden installations, making it easy to deploy in discrete access systems, hidden tag readers, or embedded devices.

Ideal for Access Control, Logistics, and Smart Management
From employee ID verification and door access to pallet tracking, smart cabinets, tool management, and automated check-out systems, the Radio Frequency Identification Sensor WS1850S MHz provides a powerful foundation for RFID-based solutions. Its combination of accurate reading, stable RF performance, and flexible integration makes it a dependable choice for anyone building or upgrading RFID-enabled applications.
