Em50 and Em50G Solar Data Loggers
Plug in Sensors, Start Logging Data
Like our standard Em50 and Em50G, these self-contained data-loggers are built to power, read, and log data from five sensors. Our solar loggers use rechargeable nickel-metal hydride (NiMH) batteries and a built in solar panel for extended deployments. Pull the battery tab to power on the logger and the NiMH batteries will charge automatically. The logger case is rated NEMA 4, IP55 for long-term outdoor use. All Decagon sensors work with the Em50 Solar and Em50G Solar without programming.
Like their counterparts, the Em50 Solar and Em50G Solar have 5 sensor ports and one communication port. They are configured by plugging a laptop into the comm port. The included ECH2O Utility software provides setup windows to name the logger, set the logger clock, select the type of sensor on each port, and specify how often you want the sensors to read.
Remote Data Access
The Em50G Solar lets you check in on your data logger from virtually anywhere in the world. Data are transmitted from the logger’s internal GSM cellular module to Decagon's secure server via cellular communication. The password-protected data are available for you to access, monitor, and download at any time. Transmitted data is backed up in the data-logger’s memory to give you an extra layer of data protection. A "confirm data transfer" protocol makes sure data transmission is correct and complete.
See signal strength and connection quality in real time as you pick the best spot for your data logger. This feature lets you test connectivity at your measurement site before you install the logger. If you have any questions about coverage for your deployment site, call us, contact us or request a quote. We are happy to help you determine if this is the right data-logger for your application site.
