Smart sensor, data rich technology

ATi’s smart, ultra-low-powered, modular M-Node sensors, utilised within our MetriNet and SiteBox solutions, were designed to generate specialist data insights, offering accurate, reliable and continuous data for real-time analysis.

Our pioneering, smart, digital M-Nodes are complete, ultra low-powered, digital water quality sensors that can run autonomously for years at a time on small batteries. Creating a neural network of M-Node sensors delivers true network digitalisation. Designed to minimise water usage and under certain conditions, operate with zero water wastage, M-Nodes can be part of a sustainable, smart water quality monitoring solution.

Used with our MetriNet and SiteBox solutions, along with bespoke solutions developed specifically to meet clients’ requirements, M-Nodes can be connected to any data gathering system, generating reliable and accurate data and communicating on a common RS485 sensor bus using Modbus protocol. Modular in nature, they allow users to assemble a monitoring package that fits individual site requirements, even in the most remote locations.
