AEI's most strategic innovations
Two technologies representing AEI's most significant engineering investment. Each has been designed, prototyped, and validated through real-world testing.
Six capability areas. All solving real infrastructure problems.
AEI's technical capabilities span six domains. Each is supported by deployed hardware and verified project outcomes.
Firmware design, sensor integration, and real-time control systems on ESP32 and Arduino platforms, engineered for environments with intermittent power and limited connectivity.
End-to-end IoT system development: device firmware, cloud backend architecture, real-time dashboards, and mobile application integration for remote monitoring and control.
Solar PV monitoring, smart prepaid energy metering, battery management systems, and GSM-enabled remote energy management. Designed for off-grid and unreliable grid conditions.
Building automation for infrastructure-constrained environments: climate control, occupancy-triggered lighting, energy monitoring, and remote management via SEMS, including offline Bluetooth control when connectivity fails.
RFID and biometric access control systems with encrypted credential management, timestamped audit logging, cloud synchronisation, and electronic lock integration.
AEI's hardware development process
Every AEI project follows a consistent engineering methodology: define the problem precisely, design for the actual operating environment, build and iterate, validate under real conditions, then deploy.
Every system here has been built and tested
These aren't concepts or renders. Each one is a real system that AEI has built and tested.
Energy Systems
Published Research
A smart prepaid energy meter that works over a mobile network. No grid infrastructure required. Remote top-up, real-time monitoring, and automatic disconnection. Published in Acta Scientific AI (2026).
Prototype
A solar panel monitoring system that logs performance data throughout the day and displays it on a live web dashboard. Useful for tracking output and spotting efficiency loss over time.
Field Deployed
AEI's smart distribution board, plus the cloud and app layer around it. Per-channel metering and switching, fire sensing inside the enclosure, schedules, priority load shedding, and Bluetooth control that carries on working after the internet drops.
Automation, Agriculture & Water
Automated soil-moisture-based irrigation controller with manual override, scheduled watering modes, and remote mobile monitoring. Designed for smallholder farms and nurseries.
IoT-enabled water monitoring and distribution control addressing water access and usage efficiency in Nigerian communities. Funded by the V2V Grant (₦1M, 2026). Currently in active development.
HX711 load cell-based LPG weight monitoring with MQ-4 gas leak detection, automatic solenoid shut-off, non-blocking buzzer state machine, and NVS-persisted two-point field calibration.
Security & Digital Infrastructure
RFID card-based ticketing and gate control for large venues. Real-time entry log, grant/deny LED indicators, admin panel, and SD card audit trail. Scalable to multiple gate nodes.
Secure institutional identity management with RC522 RFID, DS3231 RTC-timestamped logging, SD card storage, Firebase cloud sync, and SHA-256 credential security. Field-tested and deployment-ready.
What AEI hardware delivers for your organisation
Documented benefits for clients deploying AEI systems.
Per-circuit energy monitoring identifies waste and informs operational decisions with real-time data rather than estimated consumption.
Digital access control with encrypted credential management and a complete, timestamped audit trail. Provides verifiable records of all access events.
AEI's systems are designed for intermittent power, basic internet, and limited local supply chains. They run on solar, backup batteries, and hybrid setups without expensive proprietary components.
Web and mobile dashboards provide full system visibility and remote control capability from any location.
Every system is designed for difficult field conditions: dusty environments, unreliable power, basic mobile internet, and limited local supply chains.
AEI systems are field-tested prior to deployment. Where applicable, performance is peer-reviewed. The ±2% accuracy of AEI's energy metering systems was independently validated through published field research.
What AEI hardware delivered
The smart home automation system AEI built for us has dramatically reduced our electricity bill. The real-time dashboard gives us full visibility of every device. Something we never had before.
Our SWEP students gained hands-on embedded systems experience they could not get from lectures alone. The AEI team brought real engineering into the classroom.
The RFID access system was exactly what we needed. Reliable, locally supported, and genuinely more secure than what we had before. Documentation and support from AEI was professional throughout.
