Modular Industrial IoT Datalogger and Geotechnical Sensor Interface PCB Design
Pain Points (Public)
Industrial and geotechnical monitoring installations (such as dams, tunnels, and mining sites) require logging both standard RS-485 transmitters and specialized resonant sensors like vibrating-wire gauges. Off-the-shelf industrial dataloggers are often bulky, costly, and proprietary, while in-house custom designs struggle with high-voltage excitation, ultra-low power consumption for remote solar deployments, wear-resistant non-volatile storage, and multi-bearer telemetry.
Suggested Approach (Public)
Architect a modular multi-board data-acquisition platform that separates core processing and communications from specialized sensor front-ends. The host board employs an ultra-low-power STM32 microcontroller, high-endurance FRAM for high-frequency logging without flash wear-out, and hybrid LoRa and cellular LTE telemetry, while swappable expansion boards provide tuned excitation and frequency detection circuits tailored for geotechnical instrumentation.

Opportunity assessment PRO
Development brief PRO
- Treat this initially as a high-margin specialized hardware engineering consultancy for geotechnical and structural monitoring clients (such as Safe Instrumentación) rather than forcing an unvalidated standalone off-the-shelf product.
-
- Deliver Altium Designer schematics and 4-layer PCB layout for the main 'Brain' board featuring STM32G0B1RE, SPI FRAM, native USB, RS-485 transceiver, and dual LoRa/LTE-M modem interfaces.
