MJK Chatter Datalogger

LOGGING DATA TODAY IS NOT JUST PROCESSING DATA SUCH AS OXYGEN, PH OR LEVELS. WE MEASURE AND LOG DATA FROM RESERVOIRS, LAKES, RIVERS, STREAMS, CREEKS, GROUNDWATER, SURFACE WATER, HARBORS AND MANY OTHER PLACES TO HELP ADAPT AND IMPROVE OUR INFRA STRUCTURE.
Logging data far away from urban areas is handled by a battery powered datalogger, that gather information and send the information to a SCADA system, dedicated databases or even as e-mails when its suitable to do so.

Publicly placed dataloggers are vandal protected, and will send a warning when intruders act.

Sending data once a day will provide at battery life time of up to 5 years.

Information on ground water levels and early warning sewer systems in correlation with buildings nearby urban construction can save millions of Euros in damage.
