1. PRODUCT OVERVIEW
For Stevens, M2M stands for “Measurements to Mind” and means –
what the sensor Measures the Mind
sees
. Stevens Avo is the gateway between the sensors and online data analysis, visual insight, and control
via the Internet.
Stevens Avo is a complete monitoring platform that operates over cellular data networks, allowing the
configuration and transmission of data from sensors in any location within the cellular service area. Avo
includes a long-life Li-Ion battery pack as well as a MPPT solar charge controller. Data is uploaded
directly to the “Stevens-Connect” web-based program which provides centralized station control and
data management service for display, storage, computation and graphical analysis.
Stevens Avo is a paradigm shift in data acquisition that embraces the rapidly growing IoT (Internet of
Things) where all the configurations, data logging, computations, processing and interaction with the
sensors is online, and accessed anywhere there is Internet connectivity. Avo is part of the cloud-
computing process that is merging sensors, information technology, and communications infrastructure
under one interface experience. This is a shift from isolated configuration, programming, logging and
control of hardware to a centralized, cloud-based platform process.
Avo buffers sensor data ensuring reliability during periods of cellular service interruption. Advanced low-
power modes allow Avo to idle with minimal current draw for use with low-power solar systems. Logging
of sensor measurements can occur up to once per second for analog channels, and transmissions can be
scheduled to occur at a variety of intervals and as often as every 2 minutes. Between logging and
transmitting, the modem will remain in a low-power state to maximize battery life. Avo sensor interface
and reporting is remotely configurable via the “Stevens-Connect” web-based software, to allow the user
to change how often the connected sensor will log their data as well as how often transmissions will take
place.
