IoT Sensor Designs Push PCB Complexity in 2026

The July/August 2026 edition of Elektor magazine highlights cutting-edge IoT and sensor projects, including a MultiRF dev board and a Wi-Fi-based person detector using ESP32. These designs underscore the growing demand for advanced PCBs such as HDI and multilayer boards to support higher component density and signal integrity.

The new issue also features a modular environmental IoT station for field research and details on 3- and 4-Wire interfaces, reflecting the trend toward more sophisticated sensor networks. Engineers require PCBs that can handle multiple RF bands, high-speed digital signals, and compact form factors, driving interest in HDI, rigid-flex, and ceramic substrates.

As IoT deployments scale, PCB manufacturers are seeing increased orders for these advanced boards. LT CIRCUIT offers a full range including HDI Any Layer, IC Substrate-like PCBs, and heavy copper options to meet evolving design requirements for IoT and sensor applications.
