The challenge
The industrial estate team was relying on manual effort that could not keep up with volume, and every miss had a direct cost.
What we built
A phased rollout: a measured pilot first, then scale-out. The core runs on LoRaWAN with TimescaleDB, integrated into existing systems through MapLibre.
Delivery timeline
Phase 1
Discovery sprint and site survey
Phase 2
Prototype built and tested in the Motera lab
Phase 3
Pilot on site with before/after measurement
Phase 4
Scale-out, training and handover
Highlights
- Documentation, drawings and source handed over at close
- Integrated with existing PLC, ERP or GIS systems — no rip-and-replace
- Operator training delivered in Gujarati, Hindi and English
- Before-and-after measurements agreed with the client up front
