Resistive Sensor Array for Precision Manufacturing
A precision-equipment project needed to acquire a dense resistive sensor array, visualize the matrix, and produce stable records for calibration and process analysis.
Turn small resistance changes into trustworthy multi-channel evidence
The design had to manage channel density, analog noise, ADC selection, scanning timing, calibration, UI readability, and integration with the customer's equipment.

Present matrix, trend, and export views to equipment users
Co-design acquisition electronics, calibration, and software
ZedIoT combined the sensor interface PCB, 16-bit acquisition path, scanning firmware, calibration workflow, equipment-side application, matrix visualization, and data export.
Acquisition board
Multiplexing, analog front end, ADC, reference, protection, and interface design.
Calibration workflow
Channel coefficients and verification records remain tied to the array identity.
Embedded scanning
Deterministic timing and filtering produce consistent channel frames.
Measurement UI
Matrix, trend, status, calibration, and export views support equipment use.
A working prototype, not a concept-only specification
The project joined custom PCB design, precision measurement, host software, and the production application into one measurement chain.
A traceable measurement path
Sense
The array converts distributed physical changes into resistive signals.
Acquire
The analog path scans and digitizes every channel.
Calibrate
Per-channel corrections produce a comparable matrix.
Analyze
The application visualizes, records, and exports the measurement set.
One integrated sensing subsystem instead of disconnected boards and scripts
The case demonstrates how electronics, firmware, calibration, and application software can be delivered as a coherent measurement workflow.
Dense channel coverage
The 64-channel architecture supported the required sensor-array topology.
Repeatable calibration
Calibration data and operating measurements used the same traceable channel model.
Equipment-ready interface
Operators could inspect the matrix, status, trends, and exported records in one application.
Accuracy and resolution claims depend on the final sensor material, mechanics, cabling, PCB stack-up, environment, calibration reference, and production test method.
resistive sensor array system questions
What did ZedIoT deliver for this resistive sensor array system project?
ZedIoT combined the sensor interface PCB, 16-bit acquisition path, scanning firmware, calibration workflow, equipment-side application, matrix visualization, and data export. The final scope depended on the customer's devices, interfaces, operating workflow, and acceptance criteria.
Can this project pattern be adapted to another product or site?
Yes. The reusable pattern is the way sense, acquire, calibrate are connected. Device protocols, deployment topology, data ownership, and operating rules are validated for each new project.
What should be confirmed before starting a pilot?
A useful pilot starts with representative hardware, interface documentation, real operating conditions, expected users, failure cases, and measurable acceptance criteria. Accuracy and resolution claims depend on the final sensor material, mechanics, cabling, PCB stack-up, environment, calibration reference, and production test method.
