Remote control Data makes monitoring easy.

“Our on-farm research work at AgResearch requires ready access to weather data at trial sites which can be several hours drive from the office. Mark developed a very user friendly data logging and communication system for all five weather instruments at a research site. This is programmed to send data to our server daily, but better still, we can obtain current data by ringing up ‘cell phone’ in the field at any
time we like. With the solar panel, this works for months on end without requiring attention!”

Txt controlled for better results.

“For our research on farm dairy effluent we needed to develop a travelling irrigator monitoring and automatic shut-off system. Mark developed a device that senses when an irrigator breakdown occurs and automatically turns off the irrigator pump via a text message. The monitoring system has also enabled farm staff to turn the irrigator on or off remotely using their cellular phones, which is useful when they want to troubleshoot problems with the irrigator. The automatic shut-off capability of the irrigator has also given farm staff the flexibility to operate the irrigator through the night, providing more time to irrigate.”

Wireless Data makes monitoring easy.

"Recently we needed to install a passive night time warming system for our pasture global change ecology research project. The system works on the principal of a fabric cover being pulled automatically across a supporting frame at night to block night-time losses of long-wave radiation, thereby warming the soil and pasture canopy. A local engineering firm built the frames and Mark developed and built the control, data-logging and communication system. We have a total of six frames scattered across a large paddock. Not only does the system have to be activated at night but in order to minimise difference in soil moisture, the covers need to retract when it rains. In addition, to protect the fabric covering, the covers must retract during high wind speed situations. Finally, for all six frames, as well as at six unwarmed areas, soil temperature is monitored. Because the six frames are not located close to each other, communication between them and the meteorology station is wireless. Also, the research site is remote and data from the loggers are sent to a server which we can access via the cellphone network. In summary, Mark has designed and built a very sophisticated yet robust control, data-logging and communication system that we have been very happy with. Mark has been excellent to work with and I would recommend him for this kind of work without hesitation."

Versatile GPS for animal monitoring

“In our research into nitrogen cycling and nitrogen leaching losses from grazed pastures we needed to count and locate all the urine patches created by the experimental cows and sheep. Commercial GPS units were excessively expensive so we contracted Mark to custom-make units for 20 sheep and 20 cows. Being able to use so many GPS units was possible because of the much lower costs of these locally made units.
Further, Mark took our ideas on how we wanted to measure urination events and devised a cheap and very effective means logging the start and end of each event.
The combined output from the GPS and urine sensors has been a world first and has attracted a lot of interest since. Mark, of DataCarter, has worked with us for several years now designing and manufacturing unique pieces of scientific equipment.”

Convenient Data logging via the web

“For our drainage research project we wanted water flow rate data collected remotely from twenty-eight drainage and runoff tipping bucket flow meters. Mark developed an in-field data logger and communication system for allowed all the data to be accessed via the Web. He also provided useful advice on how to setup and access the data online”.
