I need a custom-built RFID reader that can reliably pick up standard identification tags in an outdoor setting. The enclosure must withstand sun, rain, and an occasional hose-down while still offering stable read range and low error rates. At this stage I am open about the operating band—LF, HF, or UHF—so long as we can balance range, power consumption, and tag cost. I expect us to discuss the trade-offs early and lock the decision in before PCB layout begins. Here is how I see the work flowing: • Electronic design—from antenna matching through to the microcontroller or SoC that will parse tag IDs and forward them over a simple UART, USB, or Ethernet interface. • Firmware—clean, documented C/C++ code (Arduino, ESP-IDF, or a bare-metal toolchain is fine) that wakes the reader, captures the tag UID, applies basic error checking, and pushes the data upstream. • Weather-resistant enclosure—3D model plus STL/STEP files suitable for injection moulding or rugged 3-D printing. • Prototype build and functional test—photos, short video, and log files proving outdoor reads of at least 95 % success over 500 cycles. Acceptance criteria 1. Reader consistently detects ISO-compliant identification tags at the agreed range. 2. Operates for 72 h on continuous duty in 0 °C-40 °C with no memory leaks or resets. 3. Complete deliverables: schematic, BOM, Gerbers, firmware source, enclosure CAD, and a concise user guide. If you have experience with antenna tuning, low-power RF design, and environmental sealing, let’s talk so we can decide on the frequency and map out the milestones.

I can develop a complete custom RFID reader for outdoor use, including hardware, firmware, PCB, and enclosure design. My approach starts with selecting the most suitable RFID technology (LF, HF, or UHF) based on your required read range, power consumption, tag cost, and environmental conditions. Once finalized, I'll design the RFID front-end, antenna matching network, microcontroller interface, power supply, and communication interface (UART, USB, or Ethernet). The firmware will be written in clean, documented C/C++ (Arduino, ESP-IDF, or bare metal) to read ISO-compliant tags, verify data, and transmit tag IDs reliably. I'll also design a weather-resistant enclosure and provide STEP/STL files suitable for rugged 3D printing or future injection molding. Deliverables include schematic, PCB files, Gerbers, BOM, firmware source, enclosure CAD, and a user guide. The prototype will be tested to verify reliable tag detection, with documentation including photos, a short demo video, and test logs targeting over 95% read success across 500+ cycles. Before starting, we'll confirm the required reading distance, tag type, communication interface, and power source to choose the optimal RFID frequency and ensure the design meets your performance goals.

Hi I can help you develop the complete outdoor RFID reader, including RF electronics, firmware, antenna system, enclosure and tested prototype. My experience includes RFID, antenna matching, low-power RF design, embedded C/C++, PCB layout, microcontrollers, communication interfaces and rugged enclosure development. The main challenge is maintaining a stable read range when rain, enclosure materials, mounting surfaces and temperature changes detune the antenna. I will address this through early LF/HF/UHF trade-off analysis, controlled antenna placement, matching-network adjustment, VNA-based tuning and environmental testing. The electronics can provide UART, USB, or Ethernet output with reliable UID parsing, error checking, watchdog recovery and diagnostic logging. I will design the enclosure with suitable seals, drainage, UV-resistant materials, protected connectors and antenna clearance for outdoor operation. You will receive editable schematics, PCB files, BOM, Gerbers, firmware, enclosure CAD, user documentation, and evidence from the required functional tests. Thanks, Bohdan Question What minimum and preferred tag reading distances are required? Will tags be stationary or moving, and how quickly will they pass the reader? What materials will the tags and reader be mounted on, especially metal or liquid containers? Which ISO tag standards or existing tag types must be supported? What power source and upstream interface are available at the installation site?
