A robust family of smart data loggers capturing measurements from diverse sensors via analog and digital interfaces. Powered by a 32-bit 900 MHz processor and 24-bit ADC with edge computing for AI-based IIoT applications.
Built to Work Together
The Altair ATRH sensor, Rigel 2 module sensor, and XTREME data logger form one bankable monitoring chain — from field to cloud.
XTREME™
Engineered for Industrial Precision
Every capability purpose-built to deliver reliable, accurate data acquisition in the harshest field conditions.

Built for Every Field Condition
From solar farms to industrial plants, XTREME delivers certified performance across the most demanding monitoring environments.
Solar WMS
Simultaneous acquisition from GHI/POA pyranometers, module temperature, ambient T+RH, wind, and soiling sensors — IEC 61724-1:2021 Class A certified.
Wind Metmast
Compliant with IEC 61400-12-1:2022 for wind resource assessment — simultaneous wind profiling, atmospheric pressure, temperature, and anemometer inputs.
Environment Monitoring
Multi-sensor air quality and meteorological logging with OPC particle sensors, PM2.5/PM10, and meteorological parameters — high-resolution 1 Hz sampling.
Energy Management
Modbus TCP and IEC 60870-5-104 integration with energy meters, inverters, and SCADA — real-time performance tracking and alarm management.
Process Monitoring
RS485, RS232, SDI12 serial interfaces and 4G LTE cloud connectivity bring any industrial process into a live IIoT monitoring platform.
Every Interface, One Device
Data Where You Need It
Live3
24×7 cloud data storage with real-time visualisation, automated alerts, and scheduled PDF reports. Access from any device, from anywhere in the world.
DALI
DALI is Aeron's browser-based software for configuring and monitoring the XTREME Smart Data Logger — accessible from any device on the network, no install required.
Activity Log
Every login and setting change is timestamped and audited, so you always know who changed what, when.
All-Protocol Acquisition, One Box
SDI-12, Modbus RTU (RS-485 & RS-232, master and slave), Modbus TCP, and analog channels — collected side-by-side.
Live Data & Live Charts
Real-time table and trend charts refreshing every second straight from the sensors, no cloud round-trip.
On-Device Calculated Parameters
Derive soiling ratio, total solar radiation, and custom maths at the edge, logged like any other channel.
Multi-Cloud Store-and-Forward
Pushes to Aeron Cloud, your own HTTP/MQTT server, and FTP/SFTP at once; buffers locally and back-fills when the link drops.
Flexible Networking & Time Sync
LAN, Wi-Fi, or built-in hotspot (DHCP or static), kept aligned by GPS or NTP.
