The SEMAT system represents a holistic package (or "one-stop shop") for environmental monitoring through measuring the following:
These measurements are then transmitted in near real-time to this web site. This information is absolutely crucial in terms of monitoring the effects of environmental change, run-off and pollutants.
Our current monitoring units utilise low-cost micro controllers and networking technologies. Our platform can be adapted for use with virtually any type of sensor and can provide multiple options for data storage, telemetry and power management. 80% of the system has been developed using recycled e-waste components. This makes the system immediately available, cheap to maintain, and adaptable to foreseeable new sensors and technologies.
The low cost associated with the system makes it pervasive. For example, 100 lower cost (potentially less precise; ≤ 5% error) monitoring units can cover a greater spatial area and provide more meaningful data than 10 expensive, highly precise competing units. These could be compared in real-time to few, high accuracy, calibrated devices for data assurance.
Our design is based on "swap and go systems" - an entire monitoring unit, or parts of the unit, can be swapped while out in the field. Technicians are not required to be present in order to deploy a new unit or make changes to an existing deployed unit. This effectively lowers the deployment costs and ensures that any faulty or damaged components can be easily fixed. We have also built in self-cleaning mechanisms for some sensor types to reduce the need for humans to service the unit.
