WHAT WE DO

Engineering capabilities
that move products forward

We combine electronics development, hardware and software design, prototype debugging and engineering validation to turn requirements into a practical development plan.

01
⌁

Intelligent Instruments

Design complete instruments around the measurement range, accuracy, repeatability, response time and operating environment—from sensors and analog front ends through calibration, interfaces and enclosure integration.

Typical work

  • Define measurands, probe conditions, calibration and acceptance criteria
  • Evaluate noise, drift, linearity and temperature effects
  • Design schematics, PCB, firmware, display and data interfaces
  • Build prototype test and calibration procedures
DELIVERABLES Feasibility review, schematics/PCB, embedded software, prototypes and agreed test documentation.

Thermal Imaging & Infrared

Integration and custom development for thermal image capture, temperature mapping and hot-spot detection, including module selection, interfaces, visualization and temperature processing.

Typical work

  • Select modules for field of view, distance, target size and ambient temperature
  • Integrate drivers, image streams and SDKs
  • Build thermal views, area measurement, alarms and data logging
  • Validate emissivity, reflected background and installation conditions
DELIVERABLES Integrated prototypes, device/PC software, interface notes and test records. Specifications depend on the selected components and use case.

Embedded Hardware & Software

Co-design MCU/ARM hardware and firmware around product functions, power, timing and interfaces. We can improve an existing board or develop a prototype from initial requirements.

Typical work

  • Platform selection, power, memory and connectivity design
  • Drivers, state machines, control logic, fault handling and updates
  • Sensor, actuator, display and wired/wireless integration
  • System bring-up, edge-case validation and stability optimization
DELIVERABLES Hardware design files, firmware source, interface/programming notes and prototypes as agreed.

Data Acquisition & PC Software

Build reliable data paths from sensors and instruments to operator terminals, covering communications, timestamps, buffering, visualization and export for field monitoring and analysis.

Typical work

  • Define channel count, sampling rate, accuracy and synchronization
  • Integrate UART, RS-485/Modbus, USB and Ethernet
  • Develop live charts, alarms, configuration and export
  • Handle reconnects, validation, logging and long-duration operation
DELIVERABLES Acquisition hardware/firmware, protocol documentation, PC software and integration records.

ENGINEERING PROCESS

A development plan you can verify

Define targets and constraints before choosing a technical route. Each stage produces reviewable outputs to reduce the risk of discovering field mismatches at the end.

01 · Requirements

Confirm use cases, users, measured objects, operating conditions, available materials and required metrics.

02 · Design Review

Break down hardware, firmware, algorithms, mechanics and software; assess key components, risks and acceptance methods.

03 · Prototype

Build within the agreed scope and integrate against real inputs, loads, interfaces and environmental conditions.

04 · Delivery

Review agreed functions and metrics, then organize design files, software, interface notes and known limitations.

Preparing for a discussion? Share the product purpose, target metrics, field photos or samples, existing circuits/protocols, schedule and budget range. Early ideas are welcome too.
