Real-Time Facility Monitoringfor Factories & Workshops
From sensor design to deployed systems - we give you real-time visibility into factory and workshop conditions, equipment behaviour, and anomalies before they become failures.
Custom PCB design, STM32/ESP32 firmware, 4-20mA sensor integration, and real-time dashboards. Built for harsh factory and workshop environments. Delivered end-to-end.

Core Engineering Services
Custom sensor systems, firmware, and dashboards built for factory and workshop environments. Every system is engineer-designed, tested under industrial conditions, and deployed hands-on.
Custom hardware and firmware for continuous, real-time facility condition monitoring. From sensor selection and PCB design to firmware development and field deployment - we own the full stack.
What You Get:
- Detect facility issues before they become failures
- Replace manual checks with continuous 24/7 monitoring
- Receive real-time alerts when readings go out of spec
- Build a historical baseline for predictive maintenance
What's Included:
- ›4-20mA sensor selection and interfacing
- ›Custom PCB design (Autodesk Eagle) - signal conditioning & enclosures
- ›STM32/ESP32 firmware development in C/C++ - interrupt-driven, <100ms latency
- ›Real-time data acquisition and WebSocket streaming
- ›Factory calibration + field validation and deployment
- ›Ongoing technical support and maintenance
Technologies:
Real-Time Monitoring Dashboards
Operational dashboards that turn raw sensor data into clear, actionable intelligence. Real-time facility status, historical trends, and configurable alerts - accessible from the shop floor or the office.
What You Get:
- See facility status at a glance - anywhere, any device
- Identify trends and anomalies before they escalate
- Configurable alert thresholds per sensor or facility zone
Technologies:
Sensor Networks & Multi-Site Monitoring
Deploy monitoring across multiple facility zones or sites from a single dashboard. Scalable wireless sensor networks with secure cloud data ingestion.
What You Get:
- Monitor multiple facility zones from one centralised dashboard
- Unified visibility across separate facilities or production lines
- Cost-effective scaling - add sensors without rebuilding infrastructure

Proof Point: iMining Facility Monitoring System
Deployed Dec 2023 - actively running. A complete hardware-to-dashboard facility monitoring system built from scratch: custom PCB, STM32 firmware, and a real-time web dashboard.
What Was Deployed
"Nduvho built exactly what we needed - a reliable monitoring system that works in our harsh environment. The system caught a pressure anomaly that our manual checks would have missed. Professional, technically solid, and delivered on time."
What Our Clients Say

What Sets Us Apart
Facility managers need systems that work reliably in harsh conditions, not consulting decks. Here is what you actually get when you work with Selah.
Engineer-Led, Not Agency-Run
Every system is designed, built, and deployed by Nduvho - a Wits Electrical & Information Engineering student specialising in embedded systems and PCB design. You deal directly with the engineer responsible for your hardware.
Production Systems, Not Prototypes
The iMining pressure monitoring system has been running continuously since 2024 at 99.2% uptime. We do not pitch concepts - we deploy working hardware into real industrial environments and stand behind it.
Built for Factory & Workshop Conditions
Our hardware is designed for dust, heat, vibration, and continuous operation - not lab environments. Sensor selection, PCB layout, enclosure design, and firmware are all optimised for the realities of a factory floor or workshop.
Hands-On Deployment & Support
We do not drop a box of hardware and disappear. Installation, calibration, field validation, operator training, and ongoing maintenance are part of every engagement. If something needs a site visit, we show up.
Supporting Your Digital Operations
Web Design & Digital Solutions
We build custom websites, landing pages, and web applications to support factories and workshops. This service funds our embedded systems R&D - facility managers understand how business works.
Built with the same engineering discipline as our hardware work: clean code, fast load times, and no unnecessary complexity.
Company Websites & Landing Pages
Professional websites for factories, workshops, suppliers, and service providers.
Custom Web Applications
Internal tools, client portals, and operational web apps built to your specifications.
E-Commerce Solutions
Online stores and product catalogues with payment integration and inventory management.
SEO & Performance Optimisation
Technical SEO, site speed optimisation, and structured data for better search visibility.
