⚡ ET SERIES – Smart Data Logger
A Reliable, Intelligent, and Scalable Data Acquisition Solution for Smart Energy and Industrial Systems
Project Overview
The ET Series Data Logger Project is a flagship development by ASW Technologies PVT. LTD., aimed at revolutionizing data acquisition and communication across residential, commercial, and industrial sectors. This project was conceptualized and implemented to deliver simplified data transfer solutions with unmatched reliability and performance.
Designed for compatibility with diverse industrial devices such as energy meters, inverters, BMS, and switchgear, the ET Series ensures seamless data logging and communication over multiple networks — Wi-Fi, RF, LoRa, 4G, and Ethernet. Each device in the ET Series is engineered to operate independently or as part of a large-scale, integrated data acquisition ecosystem.
ET (Energy Transfer) Series of Data Loggers are our newest fleet of data acquisition & concentrator modems that can work in any residential, commercial or industrial data acquisition projects. These modems can perform both in standalone applications or situations where multi-modal networks need to be established. These data-loggers are designed with a view of maximizing efficiency & reducing packet drops in data intensive applications without the need to worry about network or hardware layers that make data acquisition or reception a challenge.
