General Questions
Software
What range does an MEA Radio system have ?
The MEA Radio system uses non-licensed 433 MHz radio equipment. This means that the equipment can be installed anywhere without having to go through the process of applying for a Radio License through the Australian Communications Authority. A requirement of this band however is that transmission distance be limited to reduce the potential for interference. In practice we are achieving a range of 1 to 2km out from the base station. A simple radio survey can be performed to verify the radio path from the base station to the various monitoring sites before you purchase.
What sensors can I use with an MEA Radio system ?
The MEA Radio system is designed for use with a large variety of sensors. A small interface board at the bottom of the Field Station converts the signals from the sensors into a format which can be used by the radio. We have a large number of existing sensor interfaces and can add more if demand is sufficient. The following sensors can be used:
- Gypsum blocks,
- Theta Probe and Profile Probe,
- EnviroSMART and EasyAg,
- A range of irrigation and environmental sensors: water level, flow and depth sensors,
- Any SDI-12 compatible sensor (SDI-12 is an industry standard for connecting sensors to loggers).
What software do I use with an MEA Radio system ?
The MEA Radio system, like the majority of MEA's data logging systems is designed to display data using our Magpie software. Magpie handles communication with the data logger (whether direct or via a telephone interface) along with the display of data in tabular or graphical form.
