majiayu000 Material Tracking with IoT
Overview
This skill implements IoT-based material tracking systems for construction projects. Track materials from procurement to installation using sensors, RFID tags, GPS, and connected devices.
Tracking Capabilities:
- Delivery tracking (GPS)
- Inventory management (RFID)
- Storage conditions (temperature, humidity sensors)
- Usage monitoring (weight sensors, counters)
- Waste tracking
