The use of 24-bit ADCs ensures that there’s no loss of data or interference from noise during transmission and storage. The data from the analog sensors are modified into hi-res digital signals and the heat meters act as digital devices. The digital interface provides easier integration with big data analytics on the cloud thus making it possible to estimate trends and predict faults. Through web ports and APIs, users are able to retrieve the historical data of the smart city which helps make data driven decisions as part of the automation systems in the city’s infrastructure.
