Automatic meter reading, or AMR, is a technology that automatically collects consumption, diagnostics, and status data from water meters or energy meter devices (gas meters, electricity meters, etc.) and transmits the data to a central database for billing, troubleshooting, and analysis. . This solution uses a high-performance low-power 8051 microcontroller core, which is a wireless AMR design. The receiver in the solution has excellent sensitivity and strong anti-interference ability.
The high-performance, low-power 2.4GHz modular reference solution in this design uses the AES-128's secure coprocessor.
