Smart Monitoring
for Air Dryer Controller
Industrial IoT Gateway designed for Air Dryer Controllers with RS485 connectivity and cloud communication over Wi‑Fi or 4G LTE. The system provides real‑time monitoring, alarm notification, remote diagnostics and industrial telemetry for factory environments.
Powered by ESP32‑S3 with onboard temperature sensing, universal AC 110‑220Vac input and modular LTE support through Mini PCI‑E slot for flexible future upgrades.
Hardware Overview
System Features
Real-time Monitoring
Read up to 15 parameters from the Air Dryer controller over RS485 including pressure, temperature, alarm status, runtime and maintenance data.
Flexible Connectivity
Flexible communication options with Wi‑Fi or interchangeable LTE modem modules through Mini PCI‑E expansion.
Industrial Design
Industrial-ready design with AC 110‑220Vac input support and isolation protection for electrical cabinet installation.
Cloud Integration
Supports MQTT and HTTP API integration for dashboards, SCADA systems, analytics and cloud alert platforms.
Enclosure & Dimensions
DIN Rail Housing
The enclosure concept uses an ABS housing version approved for HB flammability rating according to UL 94, designed for compact industrial cabinet installation on standard 35 mm DIN rail.
