Sector Engagement

Industries We Serve

Hardware engineering applied to four sectors where Hexcode Plus has the deepest field evidence: hardware startups, industrial manufacturing, medical devices, and agritech.

Direct Answer

Hexcode Plus R&D serves four primary client segments from its Thiruvananthapuram laboratory: hardware startups taking a concept to a fundable prototype, industrial manufacturers retrofitting legacy machinery for IIoT monitoring, medical device OEMs requiring disciplined firmware and secure update pipelines, and agritech operators deploying long-range battery-powered sensor networks. Each engagement is backed by measured field results, not projections.

Engineering, Matched to the Problem You Actually Have

An industrial plant, a Class B medical device and a first-time hardware founder need the same underlying disciplines — PCB design, firmware, systems integration — applied with completely different priorities. The sections below describe how Hexcode Plus adapts engagement, process and evidence to each.

SECTOR 01

Hardware Startups & Founders

First-time and repeat founders need a partner who can absorb ambiguity: an idea that hasn't yet been reduced to a specification, a budget that has to stretch across the entire concept-to-prototype journey, and a timeline tied to a funding milestone or a trade show. Hexcode Plus runs this as a single accountable engagement — schematic, layout, prototype assembly and firmware under one roof — rather than routing the founder between separate PCB, firmware and industrial-design vendors.

  • Concept sketch to manufacturable PCB with working firmware, one engagement
  • KiCAD-based design (open source) so founders are never locked to a single design vendor
  • Client retains full ownership of schematics, layout files and firmware source
  • Structured for fundraising milestones: demonstrable prototype before the next round
Client outcomeConcept sketch → manufacturable PCB + firmware

“As a first-time hardware founder, I needed someone who could take my concept sketch and deliver a manufacturable PCB with firmware.” — client testimonial, about page

SECTOR 02

Industrial Manufacturing & IIoT Retrofit

Most Indian factories run CNC, injection-moulding and packaging machinery with no digital visibility into vibration, temperature or current draw — and replacing that machinery to get it is not economical. Hexcode Plus retrofits legacy equipment with ESP32-based sensor nodes bridging Modbus RTU/TCP to MQTT, giving plant engineers predictive-maintenance signals without a capital equipment refresh.

  • Non-invasive retrofit of existing CNC, injection-moulding and packaging lines
  • Modbus RTU/RS-485 and Modbus TCP to MQTT bridging for legacy PLC integration
  • Vibration (ADXL345), temperature (MAX6675) and current (ACS712) signature analysis
  • Network segmentation for IIoT security on the plant floor
Measured result37% reduction in unplanned downtime

40 machines monitored, 12-month measurement period vs. pre-retrofit baseline. See the industrial IoT deployment guide for the full methodology.

SECTOR 03

Medical Device & Regulated OEMs

Regulated hardware carries a different failure cost than a consumer gadget: a firmware bug in a diagnostic device is not a support ticket, it is a patient-safety event. Hexcode Plus firmware engineering for medical OEMs follows MISRA-C:2012 coding discipline, static analysis, and hardware-in-the-loop validation, with cryptographically verified secure bootloaders for auditable over-the-air updates.

  • Firmware architecture for Class B-adjacent diagnostic devices
  • Secure bootloader: dual-bank flash, AES-256-GCM + RSA-2048 verified OTA updates
  • MISRA-C:2012 coding guidelines with Cppcheck/Clang-Tidy static analysis
  • Documentation support for the client's regulatory submission process
Measured resultZero field failures across 5,000+ units

SECTOR 04

Agritech & Plantation Monitoring

Agricultural and plantation sites are the hardest possible environment for a connected sensor: no mains power, no Wi-Fi, and a maintenance visit that costs a full day. Hexcode Plus designs LoRaWAN sensor nodes on the STM32L0's ultra-low-power modes specifically for this constraint — multi-year deployments on primary AA cells, with 865–867 MHz India ISM-band radios reaching gateway ranges that make rural coverage economically viable.

  • STM32L0 + SX1276 LoRaWAN sensor nodes for soil, climate and irrigation monitoring
  • Multi-year battery life on off-the-shelf AA cells — no solar or mains dependency required
  • 865–867 MHz India-delicensed ISM band, adaptive spreading factor (SF7–SF10)
  • Designed for rural deployment: long range per gateway, minimal maintenance visits
Measured result3+ years battery life, 8–12 km range/gateway

STM32L0 + BME280, 1 transmission/hour; range figure is line-of-sight rural terrain. See the LoRaWAN vs NB-IoT guide for the connectivity trade-off analysis.

Industry-Specific Questions

Do you work with industries you haven't listed here?

Yes. Embedded systems, IoT, PCB design, robotics and firmware engineering apply across almost any sector that touches physical hardware — consumer electronics, automotive, defense, energy and building automation among them. The four sectors detailed on this page are where Hexcode Plus has the deepest documented field results. If your sector isn't listed, describe the problem and we'll tell you directly whether it's a fit.

Can you work under an NDA or with export-controlled requirements?

Yes, NDAs are standard practice before any detailed technical discussion, and Hexcode Plus has experience with defense and regulated-sector confidentiality requirements. Specific export control or ITAR-equivalent obligations should be raised at the initial consultation so the engagement can be scoped correctly from the outset.

For regulated industries like medical devices, do you handle certification?

Hexcode Plus engineers firmware and hardware to support the certification process — MISRA-C:2012 coding discipline, static analysis, hardware-in-the-loop validation, secure bootloaders and auditable OTA pipelines for Class B-adjacent devices. We are not a notified body or a certification authority; regulatory submission and formal certification are handled by the client's regulatory team or a specialist consultant, with our engineering documentation supporting that process.

What is the minimum project size you take on?

There is no fixed minimum, but consulting and advisory engagements (feasibility review, architecture review, component selection) typically start in the low lakhs, and full project-based development (schematic through firmware) is realistic from roughly ₹1.5–2 lakh upward depending on scope. See the pricing and engagement page for indicative bands by engagement type.
