Compliance
As compliance requirements develop our SuperSmart technology is ready to go. With unlimited cloud-based storage of all your effluent data ready to be shared directly with Regional council if needed.
How the HALO System Works
Each HALO system starts with a Gateway base station, incorporating a GSM data connection. This GSM connection communicates all on-farm data directly to our cloud based servers. Software and system updates are taken care of via this link also.
To include multiple data points across the farm we have created a low cost, high performance radio platform. HALO transmits via a mesh of repeating radio nodes each of which can record and transmit data as required. All data is made available via our secure, online HALO Dashboard.


Future Expansion
The HALO platform has the capacity to work seamlessly with our wider suite of farm management systems. Monitor milk vat storage, primary cooler efficiency, water usage, tank storage, silo level alerts, weather stations and much more.
