Welcome to Monitor One Developer Docs

The Particle Monitor One is an IP67-rated, off-the-shelf gateway built for industrial monitoring and remote asset visibility. Designed to bridge the gap between rugged hardware and flexible customization, it ships as a complete system ready to connect sensors, machines, and infrastructure with reliable cellular, GNSS, and local I/O interfaces. Whether you're doing rapid prototyping or deploying in harsh field conditions, Monitor One is engineered to simplify setup, scale securely, and deliver actionable data.

Monitor One Hero

Overview​

Monitor One includes the Tracker SoM internally, placed in a larger enclosure with space for expansion. It supports internal or external antennas for GNSS and cellular, has on-board lithium battery backup, multiple temperature sensors, and provides connectivity over standard industrial interfaces (like CAN, RS-485, 4-20 mA, 0-10 V). It’s equipped with rugged M12 connectors, external expansion card headers, and mounting options for bolting, strapping, or magnetic attachment. The device is made to operate from 6-30 V DC, with power via VIN or USB, and can be deployed virtually anywhere.

Out of the box, Monitor One includes a reference firmware and Quickstart guide to get your first data streaming in minutes. For custom hardware, you can leverage its expansion capabilities and open firmware.
