An Overview of Stevens' Approach to Making Communications Simpler, More Flexible and Incredibly Reliable
The power of the cloud’s simplicity, flexibility and reliability are the attributes at the heart of Measurements to Mind®—Stevens’ M2M cloud-based data acquisition vision of shortening the communication path from the sensors to data on-line. What the sensor measures, the mind sees. Products that fly under the M2M banner include Cell-Net, eTracker, SOLO and Stevens Connect.
Here is an overview of three (3) different remote data collection scenarios using Stevens' products that can increase the reliability of your networks, can work with virtually any existing equipment, and are super easy to install, configure and reconfigure (anytime, anywhere). The three (3) are GOES dual telemetry, eTracker and Cell-Net.
Dual Telemetry with GOES

|
|
GOES Satellite one-way transmission system leaves no way of remotely sending any command or control information to your station, such as reprogramming a data logger, obtaining diagnostic reports, or cycling power to resolve possible communications issues. The Stevens SatComm GOES transmitter provides built-in capability of supporting dual telemetry via a cell, Iridium or Inmarsat modems.

Top 9 specs to consider in a GOES transmitter in 2016
1. Option to easily add 2-way telemetry.
2. TCXO frequency controller.
3. Health status data appended to transmissions.
4. Data redundancy.
5. VSWR measurement available on-site after installation
6. Meeting all USGS and Environment Canada specifications.
7. Ability to keep accurate time for up to 28 days without a GPS fix.
8. Free and easily accessible setup software.
9. Ability to request new data right before a transmission.
Coincidentally, Stevens SatComm has all these specs!

Stevens' eTracker - The Instant Hydromet Station: Just add Water
All configuration of sensors, cell network, and communication destination all done in the cloud. The cloud is the primary data logging site with eTracker including all data transmitted on a removable SD card as backup. Stevens’ eTracker is a very simple and efficient cloud-based data acquisition platform for linking sensors directly to data on-line. If:
- you’re looking to get a few sensors up and running quickly and painlessly
- you’d love to expand your network to have more spatial coverage
- you need one or more temporary stations for a specific project
…then eTracker is a great option.

Cell-Net: Reliable Cellular Communications Made Easy
 Cell-Net eliminates the complexity of provisioning and set up while adding features that ensure your data is delivered even if the network performance is unpredictable.
- 3G GSM or 3G CDMA.
- Serial (RS232) interface with any 3rd-party data logger/RTU.
- Simplified configuration for data transmission via FTP, HTTP protocols (or both simultaneously) or IP protocol.
- Intelligent data management, data buffering, and network verification to ensure successful transmission of critical data.
- Approximately 20X typical improvement in power consumption vs. typical cellular telemetry.
