Summary:
A team from the University of Johannesburg’s School of Engineering worked on a service project to bring clean drinking to a remote village. They believed that by implementing automation and remote monitoring technology they could prevent a “give and forget” effect, where service projects fall into disrepair after a few years. Using two Unitronics PLC+HMI units, they were able to control a solar powered water pump, record data on the pumps performance and report the status of the pump via cellular communications. These versatilePLCs made it easy for the team at University of Johannesburg to ensure that the water pump continued operating at optimal levels long after the initial installation.
