EED (Estreux Electronic Development) is a South African engineering company that designs and builds data acquisition systems, weather stations, custom dataloggers and scientific software for environmental, industrial, agricultural and atmospheric research. We take projects from concept and PCB design through firmware, connectivity and field deployment, and support them for the long term.
| Environmental and atmospheric | Complete weather station systems, air quality and emissions sensors, soil moisture and temperature arrays, and remote solar powered stations for research and climate data. |
|---|---|
| Industrial process intelligence | Robust acquisition for manufacturing, mining and energy: high frequency vibration analysis, temperature and pressure monitoring, emissions tracking and SCADA integration. |
| Agricultural and precision farming | Crop monitoring sensors, irrigation management, farm weather stations and grain storage monitoring for data driven decisions. |
| Custom dataloggers | SDI-12, RS232 and RS485 sensor support; LoRaWAN and Sigfox connectivity; regulated 3.3V, 5V and 12V outputs for sensors; local storage; built for demanding field deployments. |
| Services | Consulting, project management, PCB design, custom software development, and long term support from a local team. |
Real systems we have engineered and delivered for clients across demanding operational environments, from concept through PCB design to field deployment. A short note on how each one works, and the open standards behind them.
A mains-powered industrial weighing and load-balance monitor. It measures the force on a set of load cells, works out the applied weight, and sends it wirelessly to a receiver that displays it and forwards it to a cloud dashboard. A best-of-three reading rejects a faulty cell, and the unit restarts on its own after any power interruption.
LoRaWAN / SigfoxBest-of-3 ReadingCloud DashboardCustom dataloggers paired with radar precipitation sensors for high resolution rainfall measurement. A Doppler radar measures the size and fall speed of individual drops, so rainfall rate and accumulation are derived with no moving parts and none of the maintenance or under-catch of a tipping bucket. The logger handles real time signal processing, local storage and multi protocol telemetry, giving research grade data in remote sites.
Radar SensingCustom LoggerResearch GradeGPS and GNSS satellite tracking units for livestock on large farms and conservancies. Each unit fixes its position from the satellite constellations, then uplinks over a satellite data network so it keeps reporting in areas with zero cellular coverage. Rugged enclosures and long life battery management give real time herd location, geofencing alerts and movement analysis.
GPS/GNSSSatellite UplinkGeofencingVersatile in house dataloggers supporting analog (4-20mA, 0-10V), digital (SDI-12, RS-485 Modbus) and pulse inputs. Industrial grade components, onboard storage and configurable sampling rates suit both research and industrial monitoring. Standard sensor protocols mean a single logger can read almost any field sensor without custom wiring.
Multi-ChannelSDI-12 / RS-485Industrial GradeA lightning detection and early warning system that senses cloud-to-ground and cloud-to-cloud flashes up to about 40 km away, estimates storm distance and approach, and rejects electrical interference. As a storm crosses set distance rings it raises alerts through a dashboard, an indicator and siren panel, and SMS or email.
40 km RangeStorm DistanceEarly WarningWireless silo level and inventory monitoring with self-cleaning level sensors, no moving parts and an IP68 enclosure. Readings are sent over Sigfox or cellular to a cloud dashboard for continuous stock visibility, low-level alerts and logistics optimisation, with optional solar power and SCADA integration.
