1.0 Introduction

The purpose of this User Guide is to describe the operation of a LevelSender telemetry system, including programing, installation, and data collection.

LevelSender telemetry is a simple, low cost system designed to wirelessly send data from Solinst dataloggers in the field, via GSM cellular communication, to multiple emails, an SMS (text) recipient, as well as the "Home Station" PC.

Initial setup for each LevelSender remote station is done using the LevelSender PC Software Utility and a USB connection. Each LevelSender is programmed with a "Sampling Rate", the rate at which the LevelSender collects data from the attached datalogger(s), and a "Reporting Rate", the rate at which the LevelSender reports the collected data via email and SMS.

With each report, data is sent as text to the email and SMS recipients. Data is automatically saved to a SQLite database on the Home Station PC, which the user can access for use in their own customized database. Data can also be imported by LevelSender Software at the Home Station, where emails can be viewed and saved as files, and data exported as *.xle files for use in Levelogger Software.

Changes to the sampling and reporting schedule can be done directly through a USB cable and the LevelSender Software. Alternatively, remote schedule changes can be sent to individual LevelSender stations using the LevelSender Software (via email).
