Temperature And Humidity Recorder PCB

A 2-layer FR-4 PCB built for temperature and humidity recorder devices, with green solder mask, white silkscreen, lead-free HASL surface finish, and 105um (3oz) copper. A 3.20:1 board-thickness-to-aperture ratio is held during fabrication to support the through-hole layout. The thicker copper improves current handling and thermal spreading for the sensor and acquisition front-end, while the 2-layer construction keeps unit cost low for high-volume data-logger applications. The PCB carries the temperature and humidity sensing front end, signal conditioning, MCU, memory, and interface circuitry, delivering real-time readings in environments such as cold-chain logistics, greenhouses, laboratories, server rooms, and pharmaceutical storage. Typical uses are IoT environmental loggers, instrumentation, industrial process monitoring, medical refrigeration, and energy facility monitoring where compact, reliable sensing is the design goal.
