Automatic energy meter reading, or AEMR, is the technology of automatically collecting consumption, diagnostic, and status data from energy metering devices (electric) and transferring that data to a central database for billing, troubleshooting, and analyzing. This technique mainly saves utility providers the expense of periodic trips to each physical location to read a meter using a microcontroller. Another advantage is that the billing can be based on near real time consumption rather than on estimates based on previous or predicted consumption. This timely information coupled with analysis, can help both utility providers and customers better control the use and production of electric energy, gas usage, or water consumption. AEMR technologies include handheld devices like mobile and network technologies based on telephony platforms (wired and wireless) or power line transmission.
